They produce over two-thirds of the clinically useful antibiotics of natural origin (e.g., neomycin, cypemycin, grisemycin, bottromycins and chloramphenicol). The now uncommonly used streptomycin takes its name directly from Streptomyces.treptomyces is the largest antibiotic-producing genus, producing antibacterial, antifungal, and antiparasitic drugs, and also a wide range of other bioactive compounds, such as immunosuppressants.
Streptomyces and related bacteria are characterized by their large genomic size and the presence of numerous regulatory genes. Streptomyces coelicolor A3(2) is known to posses 65 RNA polymerase sigma factors.n S. coelicolor after spore germination, which takes about 4 h at 30 Â°C, a branched network of hypha develops in the agar and on its surface, giving a colony of about 1 mm diameter after 48 h. At this stage, the colony is somewhat bald and shiny.
