Methanogens can produce methane using different organic and inorganic compounds such as carbon dioxide, acetate etc. Methanogens can also utilize the waste products of different bacteria to produce methane. Methane production can be used by the Methane production is a very versatile process which can utilize various
Then, tests are performed to determine if the products of aerobic and anaerobic respiration are present in the flasks.The citric acid cycle consists of a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of ATP (Biology). The tests detect the presence of carbon dioxide and ethanol. Carbon dioxide should be present irrespective of the type of respiration taking place, but ethanol is present only if fermentation has occurred. Another factor that can indicate whether fermentation occurred or cellular respiration occurred is the amount of glucose utilized during incubation.Fermentation uses more glucose because the process of fermentation is much less efficient than cellular respiration in terms of energy production per molecule of glucose used. The open flask (control) and the closed
Hydrogen is very important in producing water. On the other hand, methane is mainly used in heating buildings and producing electricity. 4- Anaerobic digestion: This process involves using certain organic compounds such as municipal bio-solids like sewage and animal wastes in creating methane. 5- Fermentation: This is the last method. It involves fermenting and distilling cellulose (an organic compound used in creating paper) and carbohydrates from a trees, grasses and corn.
Intrinsic and Engineered Bioremediation: A review A Aarthy(14BBT0093) firstname.lastname@example.org Vishal Joshi (14BBT0097) email@example.com Abstract: With the rise in waste production, we need methods to tackle them. The conventional methods just transfer the waste from one site to another. Bioremediation is one of the solutions for waste management which is environmental friendly, efficient and cost effective. It depends on the ability of living organisms to degrade the contaminants. Though intrinsic bioremediation processes are present, it is slow and has some drawbacks.
Biomass is not directly converted to electrical energy but several modes of conversion and extraction apply first before the main product. Here are the modes of conversion: 1. Chemical conversion There are many chemical processes that are used to convert biomass sources of energy to other forms to get electrical energy. The most known method is gastification where pressure is fed into the vessels containing energy from the solid wastes and causes combustion. The products of combustion are mixed combustibles gases such as carbon monoxide, hydrogen and other methane bonding.
A few type of bacteria, collectively called, diazotrophs (di = two, azo = nitrogen, troph = feeder}, can use nitrogen from the atmosphere, but plants can not. The most important factor possessed by diazotrophs is the enzyme nitrogenase, the key enzyme which converts dinitrogen to ammonia, coded by a cluster of genes called nif. This process requires energy which amongst diazotrophs in cyanobacteria is supplied by
Tanning industry. By analysing current potent and catalytic activity of the lipase enzyme, these are considered to be of great use in the class of industrial enzymes. After proteases and amylases which have a great use in industry, the lipases are regarded to have the third volume sales up, up to billions of dollars, showing their application flexibility and potent. They are also most chosen biocatalysts due to their unique characteristics such as chemo-, region- and enantioselectivities. These characteristics allow us to produce drugs, agroproducts and fine chemicals.
Although algae have been historically used for the domestic wastewater treatment especially for nutrients like phosphorous and nitrogen removal, phycoremediation is relatively a new term used for abatement of contaminated sites by algae and their potential for wastewater treatment is however much wider in scope than its current role. Recently, various techniques are being developed to make the process more efficient through immobilization and transgenesis of algae. Immobilization of microalgae, as part of a global trend of immobilizing microbial cells in an assortment of matrices has a wide scope in biotechnological applications. Transgenesis in algae is a complex and fast-growing technology. The present work will focus on significant role and potential of algae in pollutants removal from the wastewater and gives a brief review of recent development in the field of phycoremediation.
Many improvements have been made in manufacture the body structure of biogas digester such as change of materials to build the structure of the digester and make innovations in some or the other ways to make the digester be more efficient to produce methane gas. Biogas plants are widely used in various countries of the world after humans knew the application of methane gas. Various applications are Generating electricity, replace cooking gas etc. For example in India, the biogas plants are widely used to
The anaerobic conversion of organic matter to methane in the rumen involves a consortium of rumen microorganism with final step lead by methanogens. However, methanogens do not produce fibrolytic enzymes they enhance the energy efficiency and extend the fiber digestion by other microbes. The nature and rate of fermentation of carbohydrates influence the proportion of individual VFA formed and thereby the amount of CH4 produced in the
