4. DNA Digital Data Storage
By: Neha Sijwali (BCE IIIYear)
DNA digital data storage refers to any scheme to store digital data in the base sequence of DNA. This
technology uses artificial DNA made using commercially available oligonucleotide synthesis machines for storage
and DNA sequencing machines for retrieval. This type of storage system is more compact than current magnetic
tape or hard drive storage systems due to the data density of the DNA. These features have led to researchers
involved in their development to call this method of data storage "apocalypse-proof" because "after a hypothetical
global disaster, future generations might eventually find the stores and be able to read them." It is, however, a slow
process, as the DNA needs to be sequenced in order to retrieve the data, and so the method is intended for uses with
a low access rate such as long-term archival of large amounts of scientific data.
The idea and the general considerations about the possibility of recording, storage and retrieval of information on
DNA molecules were originally made by Mikhail Neiman and published in 1964–65 in the Radiotekhnika journal,
USSR, and the technology may therefore be referred to as MNeimONics, while the storage device may be known as
MNeimON (Mikhail Neiman Oligonucleotides). On August 16, 2012, the journal Science published research
by George Church and colleagues at Harvard University, in which DNA was encoded with digital information that
included an HTML draft of a 53,400 word book written by the lead researcher, eleven JPG images and one
JavaScript program. Multiple copies for redundancy were added and 5.5 petabytes can be stored in each cubic
millimetre of DNA. An improved system was reported in the journal Nature in January 2013, in an article lead by
researchers from the European Bioinformatics Institute (EBI).
Over five million bits of data, appearing as a speck of dust to researchers, and consisting of text files and audio files,
were successfully stored and then perfectly retrieved and reproduced. Encoded information consisted of all 154 of
Shakespeare's sonnets, a twenty-six-second audio clip of the "I Have a Dream" speech by Martin Luther King, the
well known paper on the structure of DNA by James Watson and Francis Crick, a photograph of EBI headquarters
inHinxton, United Kingdom, and a file describing the methods behind converting the data. All the DNA files
reproduced the information between 99.99% and 100% accuracy.
The main innovations in this research were the use of an error-correcting encoding scheme to ensure the extremely
low data-loss rate, as well as the idea of encoding the data in a series of overlapping
short oligonucleotides identifiable through a sequence-based indexing scheme. Also, the sequences of the individual
strands of DNA overlapped in such a way that each region of data was repeated four times to avoid errors. Two of
these four strands were constructed backwards, also with the goal of eliminating errors. The costs per megabyte were
estimated at $12,400 to encode data and $220 for retrieval.
However, it was noted that the exponential decrease in DNA synthesis and sequencing costs, if it continues into the
future, should make the technology cost-effective for long-term data storage within about ten years.
The long-term stability of data encoded in DNA was reported in February 2015, in an article by researches
from ETH Zurich.
By adding redundancy via Reed–Solomon error correction coding and by encapsulating the DNA within silica glass
spheres via Sol-gel chemistry, the researchers predict error-free information recovery after up to 1 million years at
-18 °C and 2000 years if stored at 10 °C. By adding the possibility of being able to handle errors, the research team
could reduce the cost of DNA synthesis down to ~$500/MB by choosing a more error-prone DNA synthesis method.
In a news article in the New Scientist the team stated that if they are able to further decrease the cost they would
store an archive version of Wikipedia in DNA.
The above methods of DNA storage had the disadvantage that the whole strand of synthetic DNA has to be
sequenced in order to retrieve only one of several data sets that were previously encoded. On April 2016 researchers
at the University of Washington published an encoding, storage, retrieval and decoding method that enables random
access of any one of the data sets.

Artificial Blood or Synthetic RBC
By: Tarun Pant (BCE IIIYear)
Artificial blood is a product made to act as a substitute for red blood cells. While true blood serves many
different functions, artificial blood is designed for the sole purpose of transporting oxygen and carbon dioxide
throughout the body. Depending on the type of artificial blood, it can be produced in different ways using synthetic
production, chemical isolation, or recombinant biochemical technology. Development of the first blood substitutes
dates back to the early 1600s, and the search for the ideal blood substitute continues. Various manufacturers have
products in clinical trials; however, no truly safe and effective artificial blood product is currently marketed. It is
anticipated that when an artificial blood product is available, it will have annual sales of over $7.6 billion in the
United States alone.
BACKGROUND
Blood is a special type of connective tissue that is composed of white cells, red cells, platelets, and plasma. It has a
variety of functions in the body. The white blood cells are responsible for the immune defense. The red cells in
blood create the bright red color. These cells are responsible for the transportation of oxygen and carbon dioxide
throughout the body. Currently, artificial blood products are only designed to replace the function of red blood cells.
History
The first successful human blood transfusions were done in 1667. Unfortunately, the practice was halted because
patients who received subsequent transfusions died.
In 1868, researchers found that solutions containing hemoglobin isolated from red blood cells could be used as
blood replacements. In 1871, they also examined the use of animal plasma and blood as a substitute for human
blood. Both of these approaches were hampered by significant technological problems. First, scientists found it
difficult to isolate a large volume of hemoglobin. Second, animal products contained many materials that were toxic
to humans..
In 1966, experiments with mice suggested a new type of blood substitute, Perfluorocarbon (PFC). These are long
chain polymers similar to Teflon. It was found that mice could survive even after being immersed in PFC. This gave
scientists the idea to use PFC as a blood thinner. In 1968, the idea was tested on rats. The rat's blood was completely
removed and replaced with a PFC emulsion. The animals lived for a few hours and recovered fully after their blood
was replaced. Research in this area was further fueled in 1986 when it was discovered that HIV and hepatitis could
be transmitted via blood transfusions.
Design
The ideal artificial blood product has the following characteristics. First, it must be safe to use and compatible
within the human body. It means that artificial blood can be processed to remove all disease-causing agents such as
viruses and microorganisms. Second, it must be able to transport oxygen throughout the body and release it where it
is needed. Third, it must be shelf stable. Unlike donated blood, artificial blood can be stored for over a year or more.
This is in contrast to natural blood which can only be stored for one month before it breaks down. There are two
significantly different products that are under development as blood substitutes. One is based on PFC, while the
other is a hemoglobin-based product.
6. The Biochemica Genesis 4
Perfluorocarbon (PFC)
PFC are biologically inert materials that can dissolve about 50 times more oxygen than blood plasma. They are
relatively inexpensive to produce and can be made devoid of any biological materials. This eliminates the real
possibility of spreading an infectious disease via a blood transfusion. From a technological standpoint, they have
two significant hurdles to overcome before they can be utilized as artificial blood. First, they are not soluble in
water, which means to get them to work they must be combined with emulsifiers—fatty compounds called lipids
that are able to suspend tiny particles of PFC in the blood. Second, they have the ability to carry much less oxygen
than hemoglobin-based products. This means that significantly more PFC must be used.
Hemoglobin Based Products
These hemoglobin products are different than whole blood in that they are not contained in a membrane so the
problem of blood typing is eliminated. There are also problems with the stability of hemoglobin in a solution. The
challenge in creating a hemoglobin-based artificial blood is to modify the hemoglobin molecule so these problems
are resolved. Various Strategies involves either chemically cross-linking molecules or using recombinant DNA
technology to produce modified proteins.
The Future
Currently, there are several companies working on the production of a safe and effective artificial blood substitute.
The various blood substitutes all suffer from certain limitations. For example, most of the hemoglobin-based
products last no more than 20-30h in the body. This compares to transfusions of whole blood that lasts 34 days.
Also, these blood substitutes do not mimic the blood's ability to fight diseases and clot. The current artificial blood
technology will be limited to short-term blood replacement applications. In the future, it is anticipated that new
materials to carry oxygen in the body will be found.
7. The Interview
Dr. Manoj Kandpal (2002-06)
Its our great pleasure to have an interview with Dr. Manoj Kandpal,
a graduate in B.E. in Biochemical Engineering from Kumaon Engineering
College (BTKIT) Dwarahat, currently working as a Post Doctoral Fellow in
Fienberg School of Medicine, Northwestern University USA.
Please tell something about your professional journey from KEC to onward and challenges you have faced?
After my BE from KEC, I did my M.Tech in Bio-chemical from IT-BHU, Varanasi and PhD from National
University of Singapore. I personally did not apply for any job after B.E. so I cannot comment on challenges
faced during job search. However, due to our undergraduate major being biochemical engineering, one of the
problems that most of our batch’s student faced was lack of practical knowledge in the field of genetics or
molecular biology or chemical engineering. It gave other students from biotechnology or chemical background a
competitive edge during interviews, or during their coursework for MS/PhD.
Please mark some highlights about your job profile.
Although I am still in biological domain, my research field has changed from biochemical engineering to
data-analysis to bioinformatics. Nowadays, I process and analyze next generation sequencing data from various
public domains and research collaboration. Though I have worked on data from various disease sources, my focus
is on cancer informatics.
After your B.E. you are contributing toward research as a PG student and now as a researcher. What
would you like to say about the R&D and our relations with industries during academic research?
Although research experience and publications at UG could be huge plus points in career, I have noticed that UG
is more about learning (not research), especially in India. Knowledge gained at UG helps you to get into higher
institution or job. However, if one is really interested, summer internship at companies is the best way through
which one can get a hand-on experience of various tools and techniques that are used in industries but are
unavailable at college. Having such experience could provide advantage during interviews for jobs or higher
education.
What is your scenario about impact of higher studies degree to make our career in industrial and academic
job?
I think that unless you have determination and good patience you cannot survive long in the core area after your
bachelor’s degree. Your growth will be very slow and salary would be much less for quite some time (compared
to your IT placed batch-mates). Plus, there will be very high completion from BSc and MSc candidates at entry
level. Higher degree helps you to enter at upper level position and you can grow much higher. A technical degree
will help you in core research while a management will take you to administrative roles in biotech/pharmaceutical
companies. If you want to have a career in academics (in reputable institutes), higher education and good
publications are essential requirements.
The Biochemica Genesis 5
8. The Biochemica Genesis 6
What do you think about current job market and specialized fields for a fresh biochemical engineers?
To be honest, I do not have much idea about current Biochemical markets. However, I can say that Biochemical
Engineering market is not same as it used to be about couple of decades back when its graduate could have got
core jobs in European markets, and the main completion was from Fermentation technology and Environmental
engineering researchers. The market has broadened a lot. Most of the top companies are indulging into their own
research and developments taking advantage of genetic engineering, data analysis and bioinformatics as well.
During college days what was your scenario regarding BCE department career prospects?
During our time (before 2006) there was no active T&P section and as far as I remember campus placement was
nil for all branches. Many students used to target CAT, GRE, or GATE.
What are current research fields and interesting projects in biochemical engineering?
As mentioned earlier, biochemical engineering research field has broaden a lot so one can choose from a wide
variety of research topic related to enzyme engineering, biomaterials, process optimization, drug delivery etc.
However, because the basic job of a biochemical engineer is to make chemicals in an environmentally friendly
way, I would suggest (to those who wants to remain in core) green and clean biology research e.g. biodegradable
plastics, fuel cell, environmental remediation etc.
What is your idea on role of biochemical engineering and current ongoing biochemical/biotechnological/
chemical work in “Make in India” concept?
With the current “Make in India” concept, India could soon become one of the major production houses of the
world (similar to China). However, becoming a major producer with the help of rapid industrialization could
worsen the enormous problem of air, water and land pollution. Along with setting up and operating production
plants, biochemical engineers can also help in minimizing the environmental loss.
You had enjoyed life at KEC, at prestigious institutes IT-BHU, NUS Singapore as a student and in other
prestigious universities as a research professional. What you think about implementations should be make
in KEC culture and mindset of students for success of KEC family?
Always remember that there is no shortcut to success. If you want to excel in your field, you will have to
outperform others. I am not saying that one should compromise with your fun time at college; however, it is very
important to keep a study-life balance. Further, even if you wish to work in wet lab environment try to learn basic
programming in R/python.
You are continuously working in foreign. What you think about your career and research interest in India?
So that you could contribute in Indian R&D and economic development. Because one-side morals say each
person should contribute in its nation's development.
From the very first day of moving out I have plans to return back and work in India. Working outside India has
provided me exposure to latest research along with lot of experience (I am still learning). Once I feel that I have
gained enough research experience and I could get a good opportunity in India, I would love to come back and
contribute in the best way possible.

Bispecific Monoclonal Antibody Market
By: Mohit Singh Rana (BCE IV Year)
Since the development of the first monoclonal antibody (Orthoclone OKT3) in 1975 and licenced in 1986
for its commercialization, this class of biopharmacuitical product has grown significantly in order to treat crucial
diseases and provide therapies at molecular level. The global market for monoclonal antibodies for cancer is
expected to grow to $33 Billion by 2017. Still in traditional FDA approved monoclonal antibodies, there is some
market barriers by virtue of its functioning, lack of efficacy and consequently by cost. Due to such market
competition, technology obsolescence and economic issues the respective industries are keep on looking on
Improvements and modification in traditional monoclonal antibodies for their better existence. In this line of
continuous research and development 55 years ago Nisonoff and Rivers introduced first bispesific monoclonal
antibody. Nevertheless the concept was restricted up to academic/ research level. Bi-specific monoclonal
antibodies (bsMAb) are unique and artificially engineered macromolecules with two distinct binding
specifiocities, and are capable of binding two different antigens non-covalently. However, the traditional
methods of diagnosis such as virus or bacterial isolation, and PCR amplification are quite expensive and time
consuming. Bispecific monoclonal antibodies (BsMAb) are versatile, and can increase the specificity and
sensitivity of detection in the suspected individuals. Therefore, immunodiagnostic assays using bsMAb are less
expensive, and a large number of clinical samples could be analyzed at a faster rate for the detection of
pathogens within a stipulated time. To exploit these advantageous properties of BsMAb industrialists and
researchers keep striving hard and the first demonstration of potential of using bispecific antibodies to retarget
effector cells toward tumor cells was done in the 1984. Through the results of consequent hardwork the first
BsMAb Catumaxomab (Removab®) was approved in 2009 and another was in December 2014. Due to a huge
potential in the diagnostic assays for the early detection of pathogens of human infectious diseases such as
severe acute respiratory syndrome (SARS), chikungunya (CHIKV), tuberculosis (TB) and dengue around 40
different competing formats of BsMAb are under development up to till date. These are listed in Table 1. 8-9 are
expected to be launched by the end of this decade. The BsMAb market is in growing phase. By 2024, the
BsMAb are expected to be valued at USD 5.8 billion per annum in global market.

10. The Biochemica Genesis 8
In the following years it would be obvious that BsMAb can be used to redirect immunological effector cells or
molecules toward tumor cells. Targeting an immune response to the tumor site has evolved as an attractive
concept since it recruits many effector cells and obviates several drawbacks connected with classical antitumor
responses. Industries and scientists are currently focusing on exploitation of BsMAb in crucial areas like; cancer
therapy, inflammatory diseases, and immunodignastic assay. The major goal is to address simultaneously
different targets involved in pathophysiological processes and thereby increase therapeutic efficacy. Cancer is
one of the leading causes of death worldwide, affecting approximately 13 Million people in 2012 and is expected
to grow to 17 Million by 2020. The dramatic increase in the cancer affected population reflecting the need to
highly effective and lifesaving biopharmaceuticals like BsMAb. Such a large cancer treatment market prompted
investors to invest in the oncology sector with major focus on BsMAb. By 2023, the bispecific antibodies market
is estimated to be worth USD 4.4 billion. Oncology dominates the field of bispecific antibodies. In the line of
advancement another most successful and market oriented BsMAb is Bispecific T-cell engager antibodies
(BiTEs), having ability of engaging T-cells for tumor cell elimination. Bispecific T-cell engager antibodies
(BiTEs) are single chain antibodies designed for polyclonal activation and redirection of cytotoxic T-cells to
tumor cells.
Flexibility in its desigining is helpful in genereting various BsMAb formats. BsMAb is more specific and
efficient targeting. It has optimal selectivity for activator/down-regulatory molecules. It makes high interaction
and supportive in tissue peneteration. BiTEs have increased specificity and affinity toward adoptive cellular
therapies. These special features show its huge market potential. Companies such as Trion Pharma, Amgen,
AbbVie, Ablynx, Affimedand MacroGenics, Elli lilly and company are involved in BsMAb production.
Different types of
BsMAb are being produced on the basis of chemical crosslinking, hybrid hybridomas, with the latest being
recombinant techniques. About 68% of the industry sponsored molecules are being directed against oncological
diseases; with almost two-third of them targeting solid tumors. The global oncology drugs market is expected to
reach at $111.9 billion by 2020 registering a CAGR of 7.1% from 2014 to 2020. Patent expiration of key
oncology medicines such as Herceptin, Erbitux, Rituxan and Avastin, is expected to boost the growth of cancer
biosimilars market by 2020. Going further, the biological therapies are expected to dominate the cancer market
by 2020, due to their high efficacy, target specific action and less toxicity. A number of different BsMAb based
on different technologies are in pipeline and their market can be assured on the basis of overall bio-therapies
market. Particularly, the global market for biological therapies for cancer was worth $37.9 billion in 2009 and
$53.7 billion in 2014. This number increased at a compound annual growth rate (CAGR) of 7.2%. The U.S.
market for biological therapies for cancer was worth $17.7 billion in 2009, down from $18.8 billion in 2008 and
expected to reach $23.9 billion in 2014 at a compound annual growth rate (CAGR) of 6.2%.The market for
biological therapies for cancer in Europe and the rest of the world was worth $15.6 billion in 2009, down from
$17.6 billion in 2008. This number is
expected to increase at a compound
annual growth rate (CAGR) of 7.8%
to reach $22.8 billion in 2014. An
overall previous and expected market
status is depicted in Fig. 1. North
America accounted for about ~38%
share in the overall oncology drugs
market in 2013 owing to the heavy
investments in immune therapeutics,
bio-based drugs. Similarly, Asia- Pa-
cific market is expected to grow at the
promising CAGR of 8.7% during the
forecast period.

Algal Fuel
Double Singh Karayt (BCE: III Year)
“Algal fuel” is a term used for a marine source of Omega-3 fatty acids not
extracted from fish, a source of Docosahexaenoic acid used as a dietary
supplement. Algae fuel or algal biofuel is an alternative to liquid fossil fuels that
uses algae as its source of energy-rich oils. Several companies and government
agencies are funding effort to reduce capital and operating cost and make algal
fuel production commercially viable. Like fossil fuels, algae fuel release CO2
when burnt, but unlike fossil fuel, algae fuel and other biofuel only releases CO2
recently removed from the atmosphere via photosynthesis as the plant or algae
grew. The energy crisis and the World food crisis have ignited interest in
algaeculture for making biodiesel and other biofuel using land unsuitable for
agriculture. Among Algal fuels attractive characteristics are that they can be
grown with minimal impact on fresh water. Resources can be produced using saline and wastewater, have a high
flash point and are biodegradable and relatively harmless to the environment if spilled.
Algae cost more per unit mass than other second generation biofuel crops due to high capital and operating costs
but are claimed to yield between 10 and 100 times more fuel per unit area.
The United States Department of Energy estimates that if algae fuel replaced all the petroleum fuels in the US, it
would requires 15,000 sq. miles (39,000 km^2), which is only 0.42% of the US map, or about half the land area of
Maine. This is less than 1/7 the area of corn harvested in the US in 2000.
According to the head of the algal biomass organization, algae fuel can reach price parity with oil in 2018 if
granted production tax credits.
Algae can be converted into various types of fuels, depending on the technique and part of the cells used. The
lipid, or oily part of the algae biomass can be extracted and converted into biodiesel through a process similar to
that used for any other vegetable oil , or converted in a refinery into “drop-in” replacements for petroleum based
fuels.
Example of Algae fuel :-
Biodiesel :- Biodiesel is a diesel fuel derived from animal or plant lipids (oils and fats). Studies have shown that
some species of algae can produce 60% or more of their dry weight in the form of oil. Because the cells grown in
aqueous suspension, where they have more efficient access to water, CO2 and dissolved nutrients, microalgae are
capable of producing large amount of biomass and usable oil in either high rate algal ponds or photobioreactors.
This oil can then be turned into biodiesel which could be sold for use in automobiles.
Biobutanol:- Biobutanol can be made from algae or diatoms using only a solar powered biorefinery. This fuel
has an energy density 10% less than gasoline, and greater than that of either ethanol or methanol. In most gasoline
engine, with no modifications. In several tests, Butanol consupstion is similar to that of Gasoline, provides better
performance and corrosion resistance than that of ethanol E85.
