Most bacteria are beneficial to mankind and play some economically important roles.
Biotechnology and bacteria
Biotechnology is defined as the application of organisms such as bacteria, fungi and algae to the manufacturing and services industries. These include:
Fermentation processes, such as brewing, baking, cheese and butter manufacturing, Bacteria, often Lactobacillus in combination with yeasts and molds, have been used for thousands of years in the preparation of fermented foods such as cheese, pickles, soy sauce, sauerkraut, vinegar, wine, and yogurt.
Chemical manufacturing such as ethanol, acetone, organic acid, enzymes, perfumes etc. In the chemical industry, bacteria are most important in the production of enantiomerically pure chemicals for use as pharmaceuticals or agrochemicals.
Pharmaceuticals, such as antibiotics, vaccines and steroids.
Energy, in the form of biogas.
Food products, such as beverages, dairy products, amino acids and proteins.
Agriculture, such as animal feed, composting processes, pesticides, nitrogen fixation, plant cell and tissue culture.
Microbial mining, which is the bacteria and other microorganisms are cultured in container and then used to bring these processes e.g., copper extraction.
