Biomass is a renewable energy source derived from living organisms that can be used to generate electricity or produce heat through combustion, torrefaction, pyrolysis, and gasification. It has advantages like being renewable, providing rural employment, and potentially being cleaner than coal, but also has disadvantages like having a lower energy content than fossil fuels and higher transportation and storage costs. The document discusses various methods of converting biomass into energy sources like ethanol, methane, biodiesel, and heat.
Biofuels can now be produced using bacteria with recombinant DNA rather than crops. Different types of bacteria can produce ethanol, diesel, or electricity. To produce these biofuels, genes are taken from plants or other bacteria and inserted into bacteria. These genes allow the bacteria to break down biomass like cellulose and convert the sugars into the desired biofuel. If developed further, bacterial biofuels could replace fossil fuels and reduce dependence on oil.

Biogas forms during the decomposition of organic wastes from sources like livestock manure, food scraps, and plant materials. It has advantages as a clean and renewable fuel that reduces greenhouse gas emissions. However, challenges remain in simplifying and lowering the cost of biogas production technologies. The government of Pakistan is promoting biogas use, especially in rural agricultural areas, by providing biogas plants to villages to help overcome electricity problems and develop renewable sources.
Geothermal energy can be harnessed by running pipes deep underground to take advantage of the earth's consistent temperature. This allows for efficient heating and cooling of homes without heavy reliance on weather-dependent solar panels. Researchers are also working on improving solar cell technology using quantum dots and multi-exciton generation to capture more solar energy. Additionally, some universities are developing methods to produce renewable hydrocarbon fuels using bacteria, sunlight, and carbon dioxide to potentially reduce greenhouse gas emissions and dependence on fossil fuels. Small everyday practices like short showers, collecting rainwater, and reusing water can also help conserve resources.

All living things require energy and nutrients. Producers, like plants, make their own food through photosynthesis, while consumers obtain energy and nutrients by eating other organisms or their byproducts. Energy flows through organisms from the environment and is never recycled, only flowing in one direction before being lost as heat. All organisms sense and respond to changes internally and externally to maintain homeostasis. DNA carries hereditary information that guides development, growth, reproduction, and is inherited, leading to similarities and variations between individuals and species.
This technical presentation discusses bio batteries. Bio batteries use enzymes to break down glucose from sources like human blood to directly produce energy, which is then stored in the battery. Bio batteries consist of an anode, cathode, electrolyte and separator.

Genetic Engineering, Biofuels and the Environmentwizon23
This document discusses using genetic engineering to increase the efficiency of producing biofuels from lignocellulosic biomass and algae. Researchers have genetically modified bacteria and algae to more effectively break down plant cell walls and convert the materials into fuels like ethanol and diesel. One approach involves modifying lignin synthesis in plants to make cellulose more accessible for breakdown. Other work focuses on engineering cyanobacteria and E. coli to directly produce hydrocarbon fuels from carbon dioxide and sunlight. These genetic techniques aim to develop renewable fuels that can replace fossil fuels and address environmental issues.
This document discusses how biotech tools are helping to convert carbon dioxide into useful products through genetic engineering of microorganisms. Several companies are engineering cyanobacteria and other microbes to produce fuels and chemicals like ethanol directly from CO2. One company has genetically modified Synechococcus cyanobacteria to overexpress enzymes to produce ethanol from CO2. Another company is using Clostridium bacteria optimized through directed evolution to produce ethanol from waste gases from steel plants. These approaches aim to provide carbon capture and utilization at smaller scales than traditional chemical approaches.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
