FASCINATION ALGAE - an enourmous potential
It is estimated that there are between 250 thousand to several million dif-ferent algae species. Thereof only 35 000 species have been scientifically recorded so far.
There are around 5 thousand algae species available from culture collec-tions around the world. However, only round 20 species are currently utilized for commercial applications.
Given the commercial applications of today have been achieved with only a few microalgae species, the thousands of still undiscovered and unu-tilized species present a huge potential for further economic exploitation.
A TEXT BOOK : Complete and comprehensive inputs in Learning about Biogas and Biogas digestors:We have tried to take the mystery away from biogas.
Biogas is a renewable energy source with many different production pathways and various excellent opportunities to use.
One main advantage of biogas is the waste reduction potential. Biogas production by anaerobic digestion is popular for treating biodegradable waste because valuable fuel can be produced while destroying disease-causing pathogens and reducing the volume of disposed waste products.
Biogas burns more cleanly than coal, and emits less carbon dioxide per unit of energy. The carbon in biogas was recently extracted from the atmosphere by photosynthetic plants. Releasing it back into the atmosphere adds less total atmospheric carbon than burning fossil fuels.
Thus, biogas production kills two birds with one stone: it reduces waste and produces energy. In addition, the residues from the digestation process can be used as high quality fertilizer. This closes the nutrient cycle.

Generally, biogas is a renewable fuel. In any country, for cooking or heating purposes biogas can be used as a low-cost fuel. Biogas can be used as a fuel in stationary and mobile engines, to supply motive power, pump water, drive machinery (e.g., threshers, grinders) or generate electricity. It can be used in both spark and compression (diesel) engines. The spark ignition engine is easily modified to run on biogas by using a gas carburetor.

ENV330 Module 4 AVP Transcript
Title Slide
Narrator: In Module 4, we will consider the impact of food production and distribution and sustainable
food production. The total amount of food grown and produced for humans has increased dramatically
over the past 50 years to meet the growing demands of our human population. Agricultural production,
meat production and fish catch, both wild caught and aquaculture have all increased dramatically. The
world’s three largest grain-producing countries are China, the United States, and India.
What kinds of stresses has this placed on the natural capital and ecosystems of the world?
Slide 2
Title: Impacts of Food Production
Slide content:
[image of a desert]
Narrator: The impacts include loss of biodiversity, soil degradation, wasting and pollution of scarce water
resources, increased greenhouse gas emissions, depletion of fish stocks in the oceans, and human
health problems. According to a 2002 study by the United Nations, nearly 30% of the world’s cropland
has been degraded to some degree by soil erosion, salt buildup, and chemical pollution, and 17% has
been seriously degraded.
There are serious soil erosion problems on every continent of the world, and marine biologists say that
we’ve “fished out” much of the oceans.
Slide 3
Title: Dust Bowl in 1930’s
Slide Content:
[black and white image of a dust cloud taking over a town]
Narrator: Overgrazing, poor agricultural practices including salinization from irrigation can cause erosion,
desertification and dust storms. Deforestation of hillsides can also impact agriculture and ecosystems.
Once a hillside has been deforested for timber, fuelwood, livestock grazing, or unsustainable farming,
water from precipitation rushes down the denuded slopes, erodes precious topsoil, and can increase
flooding and pollution in local streams. Such deforestation can also increase landslides and mudflows. A
3,000-year-old Chinese proverb says, “To protect your rivers, protect your mountains.”
Waste of water is one of the major environmental problems associated with agriculture. The most
efficient (90-95%) way to get water to the roots of crops is through drip irrigation, or Low Energy Precision
Application (LEPA), which you will learn about in this module.
During the Dust Bowl in the US in the 1930’s, terribly unsustainable agricultural practices in the Midwest
breadbasket led to such dire conditions that millions of starving people migrated away from the farmlands.
Many children died from inhaling the dust. The situation got so bad that during a Senate hearing on the
issue in DC, dust from a dust storm leaked into the conference room!
A few inches of top soil is all that keeps civilization from starvation – we need to protect this vital natural
capital.

Kevin Litwiller - Director of Business Develoment for Lystek International presents the changing trends and landscape of wasterwater biosolids and residuals management. The key points made include:
1) We must view biosolids as a resource not waste
2) Agriculture 3.0 - a shift to small, family farms to much larger sophisticated operations - demands the nutrient rich, organic matter in biosolids be safely recycled to meet the needs of sustainability
3) Concerns about biosolids odours and pathogens are contributing to a shift toward advanced treatment/technologies - Class A Solutions
Removing carbon out of the air by bioenergy crops compressedEmiliano Maletta
Growing biomass with regenerative agriculture approaches becomes a solid and commercially mature opportunity by providing biofertilizers and a carbon negative solution and green energy, animal feed and biomaterials access to reduction costs. A growing bioeconomy in next 30 years becomes also influenced by carbon bonds reaching prices between 25 and 75 USD/tCO2 captured and/or sequestered. Biochar production and bio-coal filtering products take value added products between 400 and 2000 USD/ton and feedstock costs range 30 to 120 USD/ton. Coupled thermal applications are part of the system therefore allowing developers to process several fossil based products such as steel, cement or plastics into a lower footprint alternatives. Commercial applications are feasible and available in most markets with high level of demonstration (high Technology Readiness Index).

Photobioreactors for laboratory cultivation of microalgae.
Subitec‘s cultivation technology is based upon a specially shaped and cost-effective plate reactor. The patented and uniquely designed photobioreactor induces a circular flow of the suspension by aerating with air/CO2, continuously moving algal cells trough zones of diverse light intensity.
Commercial Microalgae Cultivation in Industrial Scale with Subitec Flat Panel Airlift Photobioreactors
The patented Flat Panel Airlift (FPA) photobioreactor was designed for industrial scale production of microalgae biomass. Unlike many other reactor types the FPA is capable of utilizing very high light intensities without the need for shading and algae are efficiently transferred to light. The Subitec FPA reactor is an excellent choice for industrial cultivation application. Excellent productivity, high culture density and high process integrity are key features of the Subitec FPA reactor.
Industrial Microalgae Cultivation Artificial Lighting of High-Density Flat-Panel Airlift Photobioreactors
In this short-communication on artificial lighting, I will give you insights into our activities and findings. regarding the lighting of systems for the indoor production of photosynthetic microorganisms.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
