Answer:
Useful Microorganisms include:
1. Saccharomyces cerevisiae: winemaking, baking, and brewing since ancient times.
2.Aspergillus oryzae: used for waste management and biotransformations in addition to its industrial uses, such as production of citric acid and extracellular enzymes.
3.L. plantarum:used as a starter and adjunct cultures in fermentations of raw materials from plant and animal origin, where it contributes to enhance sensorial quality and shelf life of the fermented products.
4. Thiobacillus ferrooxidans: Thiobacillus, widespread in marine and terrestrial habitats, oxidizes sulfur, producing sulfates useful to plants; in deep ground deposits it generates sulfuric acid, which dissolves metals in mines.
5. Corynebacteria.used for very important industrial applications, such as the production of amino acids, nucleotides, and other nutritional factors.
6.Rhizobium; helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development.
7. yeast: used to cause fermentation and leavening. The fungi feed on sugars, producing alcohol (ethanol) and carbon dioxide; in beer and wine manufacture the former is the desired product, in baking it is the latter.
8. lactobacillus: used for diarrhea, including infectious diarrhea and diarrhea in people taking antibiotics. Some people also use lactobacillus for general digestion problems, irritable bowel syndrome
9. penicillin: Acts as antibiotics
