    Lactobacillus spp and other bacterial species carry out a similar anaerobic fermentation of harvested grass to produce silage. The acid waste products of this fermentation preserve the grass, so it can be fed to farm animals even when grass is not available to graze. This is particularly important in areas of the world with cold winters or very dry seasons. Respiratory substrates…

    Secondary sewage treatment promotes the biological transformation of dissolved organic matter to microbial mass and carbon dioxide. They remove 75-95% of the BOD and many bacterial pathogens are removed by this process which will ultimately increase dissolved oxygen. Under some toxic conditions, the dissolved organic matter will be transformed into additional microbial biomass plus carbon dioxide. When the microbial growth is completed, under ideal conditions microbes will aggregate and form a stable structure which can then be removed (Cooke, n.d.).…

    Renewable Energy

    In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

    The manure also creates perfect conditions for the growth of fecal bacteria, like E. Coli (Indiana Water). “To prevent pollution from livestock operations, CAFOs and the manure they generate should be barred from sensitive areas like floodplains and cave country, where minute amounts of pollution can trash essential underground aquifers” (Indiana Water). Although there are many ways to prevent pollution from CAFOs, farmers do not always follow the protocol and precautions recommended for safe storage and removal of chemicals and manure. “The huge basins or “lagoons” where CAFOs store manure by the tanker truckload should have to be leak-proof and set back a safe distance from homes and waterways. And if there are spills, good inspection, enforcement and penalties should ensure that polluters pay a price” (Indiana Water).…

    * In this experiment carbohydrate catabolism was first tested under aerobic conditions. We began this by drawing three sections on the bottom of the petri plate, dividing it into three sections. Using a sterile loop, we streaked a single line of each culture Bacillus subtilis, Pseudomonal aeruginosa, and Escherichia coli, to each of the separate sections. The plate was incubated until the next lab period, where we then flooded the plate with Iodine and were able to observe and record starch Hydrolysis. (Table 1)…

    Oxygen in the body is depleted by aerobic organisms; creating an ideal environment for the new creation of anaerobic organisms. Anaerobic organisms from the gastrointestinal tract and respiratory system transform carbohydrates, lipids, and proteins yielding organic acids (propionic acid, lactic acid), and gases, (methane, hydrogen sulphide, ammonia). The process of microbial proliferation within a body is referred to as putrefaction and leads to the second stage of decomposition.…

    Introduction: Enzymes are “specialized proteins made by living cells that serve as biological catalysts.” (eScience Labs, LLC, 2013) These enzymes “allow certain industrial processes to be carried out at normal temperatures and pressures, thereby reducing the amount of energy and expensive equipment needed.”(BBC, 2012) Enzymatic activity can be affected by three factors, pH, salt, and temperature. In this project, we will be seeing how acidic fluids will affect the enzymatic reactions. Furthermore, this experiment will answer the following questions: What level of pH there must be in order for the reaction to slow down, or speed up? Are there specific levels of ph levels that speed up enzymes? Seeing that enzymes tend to do great on themselves, my hypothesis is that acid fluids (low pH levels) will actually hinder the enzymatic reaction. My reasoning behind this is that the substrate will take a longer time to mix with the fluid acids, and thus much of the time will be wasted when the enzyme makes contact with the combined substances.…

    Many types of bacteria respire anaerobically. In other words, they can go through the process of respiration without oxygen present. Instead of using oxygen to help them burn the energy in their food, these types of bacteria use other naturally-occurring chemicals to create chemical reactions and release the energy they need. Common naturally-occurring chemicals used include nitrates, sulfates and carbon dioxide. Anaerobic respiration in bacteria generally creates many byproducts. Many of these byproducts can be toxic or dangerous to human beings and include ethanol and hydrogen. Here is a deeper explanation.…
