Isolation, Production and Purification of Antibiotics Isolation from Microbes from Soil
Abstract: A chemical compound acting against life is called antibiotics. The term “antibiotic” literally means “against life”. The term appeared as early as 1928 in the French microbiological literature as antibiosis. The phenomenon of antagonism between living organisms was frequently observed even since 1877, when Pasteur and Joubert noticed that aerobic bacteria antagonized the growth of Bacillus anthracis. However, the world in its present restrictive meaning, “a chemical substance derived from …
