Microorganisms used refers to a broad set of microscopic organisms—bacteria, yeasts, molds, algae, and some viruses—that are harnessed for practical purposes. They are valued for rapid growth, metabolic versatility, and the ability to operate under relatively mild conditions.

In food and beverage production, Saccharomyces cerevisiae converts sugars to ethanol and carbon dioxide, enabling bread making and fermentation of beer and wine. Lactic acid bacteria ferment dairy and vegetable products, producing lactic acid and distinctive flavors. Filamentous fungi such as Aspergillus and Penicillium generate enzymes and aroma compounds used in cheese, soy sauces, and citric acid production.

In biotechnology and medicine, microorganisms are used to produce proteins, enzymes, antibiotics, and vaccines. Recombinant bacteria and yeasts express human insulin, growth factors, and therapeutic antibodies. Model organisms such as Escherichia coli and Saccharomyces cerevisiae underlie much of molecular biology research and biotechnology development.

In agriculture, nitrogen-fixing bacteria such as Rhizobium form symbiotic nodules on legume roots, supplying usable nitrogen. Other bacteria and fungi promote plant health through nutrient solubilization or biocontrol of pests and diseases.

In environmental and industrial applications, microorganisms support bioremediation by degrading pollutants, and participate in wastewater treatment through microbial consortia. Anaerobic digestion uses methanogenic microbes to produce biogas, while microbial enzymes enable greener chemical processes.

Safety and regulation emphasize containment, risk assessment, and standardized quality control, reflecting the variable properties of different microorganisms and their potential impacts on health and ecosystems.
