The principle behind this test is to use enzymes native to the organism to create a colored product in the presence of foreign molecules. The chemical 5-bromo-4-chloro-3-indolyl-beta-D-galactoside is used in the test because N. lactamica can hydrolyze it with the production of β-galactosidase, turning the
Microbial pesticides, usually a virus, bacterium, or fungus are used to control pest populations in a more specific manner. [6] The most commonly used microbe for the production of microbial bio-pesticides is Bacillus thuringiensis, also known as Bt. This spore forming bacterium produces a delta-endotoxins in which it causes the insect or pest ...
Scientists have also exploited their knowledge of microbes to produce biotechnologically important enzymes such as Taq polymerase, [27] reporter genes for use in other genetic systems and novel molecular biology techniques such as the yeast two-hybrid system. [28] Bacteria can be used for the industrial production of amino acids.
Industrial fermentation can be used for enzyme production, where proteins with catalytic activity are produced and secreted by microorganisms. The development of fermentation processes, microbial strain engineering and recombinant gene technologies has enabled the commercialization of a wide range of enzymes.
Enzyme denaturation is normally linked to temperatures above a species' normal level; as a result, enzymes from bacteria living in volcanic environments such as hot springs are prized by industrial users for their ability to function at high temperatures, allowing enzyme-catalysed reactions to be operated at a very high rate.
Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira and Nitrococcus. These bacteria get their energy from the oxidation of inorganic nitrogen compounds . [ 1 ]
In comparison, microbial amphiphillic compounds have robust a tendency to stay functional in extreme environments such as areas with high heat or extreme ph. all while being biodegradable and less toxic to the environment. This efficient and cheap method of production could be the solution to the ever increasing global consumption of surfactants.
Microorganisms are used for many commercial and industrial purposes, including the production of chemicals, enzymes and other bioactive molecules, often through protein engineering. For example, acetic acid is produced by the bacterium Acetobacter aceti , while citric acid is produced by the fungus Aspergillus niger .
