Industrial processes which uses bacteria

Question

What are various industrial processes which use bacteria?

Answer 1

Bacteria are employed by industry in different ways. There are vaccines made up of attenuated pathogenic bacteria or of antigens existed in bacteria. One of the most olden uses of bacteria is the fermentation of milk to make yogurt, cheese and curd (that is, even before the knowledge of the presence of bacteria such microorganisms were already employed in the making of such products). Some techniques of antibiotic production comprise bacteria. The recombinant DNA technology (or genetic engineering) permits the industrial production and commercialization of human proteins, such as insulin for diabetics, synthesized by mutant bacteria. Many bacteria can generate fuel, such as methane gas.
