Microbiology - A branch of biology, that deals with all members of the microbial world Classes of Microbiology - Bacteria, Fungi, Protozoa, Algae and "viruses." Beneficial Bacteria - The majority of the bacteria are beneficial. Only about 3% are harmful. Examples of benefits we get from bacteria and fungi include - Bacteria and fungi decay organic matter. Most antibiotics are made by bacteria and fungi. Normal flora contribute to health. Intestinal bacteria are involved in pr...
