5.Microbes are used to reduce pollution. For example, decomposers such as bacteria and fungi break down dead bodies and excreta to form inorganic compounds, which plants can absorb.
6.Microbes also play an important role in the preparation of medicines. Antibiotics are chemicals produced by microorganisms to kill bacteria. Penicillin is an antibiotic made from Penicillium.
7.Bacteria in our intestine helps in proper digestion and release vitamin B, absorbed by the intestine.
