Anaerobic Respiration

# The respiration process, which uses oxygen as its terminal electron acceptor, is called  aerobic respiration and while in anaerobic respiration terminal electron acceptor is not oxygen. # Anaerobic respiration refers to the special type of respiration, which can take place without oxygen.   Anaerobic respiration is the oldest form of cellular respiration that is carried out by single celled organisms, especially in anoxic environments such as riverbeds, lake mud, bio-gas plants etc. # It is a process of oxidation of molecules in the absence of oxygen, which results in the production of energy in the form of ATP. This process is relatively less energy yielding than the aerobic respiration process like for example in alcoholic fermentation or the anaerobic respiration two molecules of ATP are produced for each glucose. # Bacterial anaerobic respiration is one of the most ancient and essential metabolism processes, which have characteristics of both  flexibility ...

Microbial Nutrition

A nutrient is a element or chemical substances that nourishes or promotes growth and repairs the natural damage of organic life. Organic and Inorganic compounds are included as nutritional requirements. Organic nutrients include carbohydrates, fats, proteins and vitamins. Inorganic chemical compounds such as dietary minerals, water and oxygen etc. Nutritional requirements: * The biomass of microorganisms can be measured by determining the fresh weight or the dry weight, the fresh weight contains about 80-90 % water and remaining is dry matter.The dry matter  is composed of 50% proteins, 10-20% cell wall materials, 10% lipids, 10-20% RNA, 3-4 % DNA. * Microbial nutrients are further classified as Macro Nutrients and Micro Nutrients depending upon the amount required. Macro Nutrients ( C, O, H, N, S, P, K, Ca, Mg, Fe) :- #  There are 10 macro nutrients present, because they are required by micro organisms in relatively large      ...
