Simultaneous Saccharification and Fermentation of Watermelon Waste for Ethano...Ratnakaram Venkata Nadh
As the world oil reserves are draining day by day, new resources of carbon
and hydrogen must be investigated to supply our energy and industrial needs. An
extensive amount of biomass is accessible in many parts of the world and could be
utilized either directly or as crude material for the production of different fuels. The
motivation behind the present research is to find an appropriate strain for the fermentation
of watermelon waste to get ethanol. Saccharification and fermentation (SSF)
of watermelon waste were carried out simultaneously in the presence of A. niger and
S. cerevisiae (toddy origin and baker’s yeast). Toddy originated S. cerevisiae culture
is found to be more active than that of baker’s yeast. For the ethanol production, the
optimized conditions for different parameters like temperature, time, strain and pH
are finalized.
Cassava Retting Water An Alternative Source for Industrial Cellulase EnzymeYogeshIJTSRD
Cassava fermentation is one of the teaming businesses in almost all the tribes of Nigeria. Among all the methods of cassava processing to food, fermentation is the most used. This produces foul smelling waste water that causes environmental pollution to man and animals. The retted cassava water was checked for cellulase enzyme activity to see if it can be a source of cellulase for used in food, paper, textile and other industries. The aim of this work is to seek a way of utilizing the waste water as source of enzymes as this will reduce the importation of these enzymes and make them available always. Cassava tubers were peeled, cut into cylindrical portions of about 3 5 cm and washed. Two hundred grams of the washed tubers were soaked in 5 liters of water and allowed to ret. The retting water was analyzed daily for titratable acidity, cyanide content, pH, cellulase activity and the microbial flora were isolated and identified. Results showed that titratable acidity rose from 0.20 to 2.76 mg g and cyanide content increased from 0.28 to 4.69 mg ml while pH fall from 7.2 – 6.0 tending acidic. Retting started on the 2nd day and complete retting was achieved on the 4th day. ß glucosidase activity rose from 0.05 to 8.0 µ mol, Filter paper activity increased from 0.06 to 7.5 µ mol and carboxyl methyl cellulase CMC activity increased from 0.05 to 7.7 µ mol. Ten organisms Aspergillus fumigatus, Rhizopus stolonifer, Bacillus subtilis, Candida utilis, Citrobacter sp, Enterobacter aerogenes, Lactobacillus coryneformis, Saccharomyces cerevisiae, Staphylococcus aureus, Streptococcus feacalis were isolated from the retting water. Daily increase in the enzyme activities showed that cassava retting when done in a large scale can yield large quantity of enzymes. This will reduce the importation of industrial enzymes and reduce the environmental pollution caused by the waste water. Umeh, S. O. | Nwiyi, I. U. | Dimejesi, S. A. | Ikele, M. O. | Ugwu, C. H.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. WASTE:
It is any unwanted, undesirable, discarded or intended to be
discarded material left over the
Completion of a certain process.
Also referred to as rubbish, garbage, trash or junk.
Food processing industry are divided in to many divisions and
among them an important industry is tuber industry.
3. Tubers
Enlarged structures
storage organs for nutrients
used for the
plant's perennation (survival of the
winter or dry months)
to provide energy and nutrients for
regrowth during the next growing
season
As a means of asexual reproduction
Common plant species with stem
tubers include potato and yam
Examples of modified lateral roots(root
tubers) are sweet potato, cassava,
and dahlia.
4. Potato processing
Potato processing waste leads to pollution
Peeling leads to removal of some starch
along with peels
Integrated production of bioethanol and bio
manure
1step:Ethanol production from potato peel
and mash waste by employing co-culture of
Aspergillus niger , Saccharomyces cerviciae
at various incubation time (24–120 h) instead
of application of enzymes.
The solid state fermentation of potato peel
and mash inoculated with co-culture,
resulted in bioethanol production of 6.18%
(v/v) and 9.30% (v/v) respectively.
In the second part of the work, the residue
obtained after ethanol production was
inoculated with seven different
microorganisms (Nostoc
muscorum, Fischerella
muscicola, Anabaena variabilis, Aulosira
fertilissima, Cylindrospermum
muscicola, Azospirillium
lipoferum, Azotobacter chroococcum) and
mixture of all the organisms in equal ratio
for nitrogen (N), phosphorous (P) and
potassium (K) enrichment.
Among them, A. variabilis was found to
enrich N, P and K content of the residue by
nearly 7.66, 21.66 and 15 fold than that of
the initial content, ultimately leading to
improved N:P:K ratio of approximately 2:1:1
7. Cassava industry
Low value cassava waste have been converted to bio-
sorbents which can remove toxic and valuable metals
from industrial waste water.
Distilled alcoholic beverage with acceptable quantity of
cyanide can be produced from the effluents of cassava
industry.
Cassava starch powder can be utilized as an alternative
for solidyfying agents such as agar-agar.
13. Cocoyam tubers
• The amount of starch is used for production of ethanol and vinegar
• 2 steps:
• 1. alcoholic fermentation: Saccaromyces carlbergensis
• 2. acetic acid fermentation: Acetobacter sp
• Saccarification of gelatinized mash involves 2 stage enzyme hydrolysis
• Bacterial and fungal alpha-amylase to produce fermentable sugars
14. Protein enriched yam powder
• Conventional sources of protein are becoming inadequate for protein-based food supply.Solid state
fermentation (with and without ammonium sulphate) of yam peels was carried out for 96 h,
using Saccharomyces cerevisiae .
• Samples from fermented biomass were collected at 24 h interval for 96 h, oven dried at 60 °C, cooled,
milled and assayed for chemical and amino acid composition.
• The crude protein, true protein, fat and ash contents increased significantly from 6.60%, 4.38%,
1.12% and 4.45% to 15.54%, 13.37%, 2.09% and 8.02% respectively when fermentation reached 96 h
in the presence of ammonium sulphate.
• High protein content with good amino acids profile (leucine, valine, lysine and threonine as essential
amino acids) was recorded in ammonium sulphate supplemented peels fermented for 96 h.
• Remarkable increase in protein and amino acids suggested that ammonium sulphate supplement
influenced the biomass protein yield and quality.
15.
16. Sweet potato
• Rich in carbohydrates and minerals
• 90% of carbohydrate & 60-70% of starch
• Alcoholic beverages, ethanol, flour etc
• Mostly wastes are not utilized
• Vines, leaves are major wastes
• Uganda uses sweet potato to a maximum as food-
83%.
• China-53% as feed
• US-95% food;3.6%as feed
