ANTIBIOTICS The growth of microorganisms in nature might be influenced by the presence of other microorganisms. When the influenced is unfavorable or harmful, it is known as antibiosis. Substances produced by microorganisms that inhibit the growth of other microorganisms at very low concentrations are called antibiotics. Antibiotics have been put to good use controlling the activities of harmful bacteria.
