Antibiotics and Antibiotic Resistance

MICROORGANISMS PRODUCING ANTIBIOTICS

Antibiotic is one of the most important commercially exploited secondary metabolites produced by bacteria, fungi and Streptomyces and employed in a wide range. Most of the antibiotics used today are from the microorganisms that live in soil. Bacteria are easy to isolate, culture, maintain and to improve their strain. The main producers of the microbial metabolites, the actinobacteria, fungi and other filamentous bacteria, represent inexhaustible sources for the future.
