Question

In the world many industries totally depend upon microbial activities. For example, Oxalic acid is the fermented product of fungi Aspergillus niger. Name any two bacteria used in the industry with their product.

Answer 1

Industrial microbiology is a branch of applied microbiology in which microorganisms, such as medicines, chemicals, fuels, and energy, are used in industrial processes.

Complete answer:
There are different kinds of microorganisms that are used to make industrial products on a wide scale. Some of the examples we are talking about below are:
Xanthomonas, a form of bacteria, is capable of producing the acidic exopolysaccharide commonly sold as xanthan gum, used in foods and cosmetic ingredients as a thickening and stabilizing agent to prevent separation.
The amino acids that Corynebacterium glutamicum produces include the amino acid glutamic acid, in particular. As a common additive in the manufacture of food, glutamic acid is used.
Because of the enzymes and molecules, they generate that allow them to maintain life in extreme climates, including very high or low temperatures, extremely acidic or simple solutions, or when they are exposed to other harmful factors, including radiation, Archaea species are of particular interest. Unique enzymes that have been isolated for industrial purposes and used.

Note: Microbes are also useful in following fields:
ANTIMICROBIALS/ANTIBIOTICS: Microorganisms may be modified using conventional genetics or recombinant DNA techniques to increase the yield or action of antibiotics and other antimicrobial agents.
VACCINES: To protect humans and animals from microbial diseases, vaccines are important. For example, the hepatitis B vaccine.
AGRICULTURE: In order to boost microbial inoculants that act as fertilizer supplements by fixing atmospheric nitrogen to enhance plant yields and to serve as plant pest controls, conventional, recombinant DNA and monoclonal antibody techniques are used.
