Streptomyces griseus is a species of bacteria in the genus Streptomyces commonly found in soil. A few strains have been also reported from deep-sea sediments. It is a Gram-positive bacterium with high GC content .
Cycloheximide is a naturally occurring fungicide produced by the bacterium Streptomyces griseus.Cycloheximide exerts its effects by interfering with the translocation step in protein synthesis (movement of two tRNA molecules and mRNA in relation to the ribosome), thus blocking eukaryotic translational elongation.
Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. [3] Over 700 species of Streptomyces bacteria have been described. [ 4 ] [ 5 ] [ 6 ] As with the other Actinomycetota, streptomycetes are gram-positive , and have very large genomes with high GC content .
Streptomyces griseofuscus is a bacterium species from the genus of Streptomyces which has been isolated from soil in Japan. [ 1 ] [ 2 ] Streptomyces griseofuscus produces azinomycin A , azinomycin B , bundlin A , bundlin B , moldicidin A , physostigmine , fungichromin and pentamycin .
As human and bacteria both have ribosomes, streptomycin has significant side effects in humans. At low concentrations, however, streptomycin inhibits only bacterial growth. [18] Streptomycin is an antibiotic that inhibits both Gram-positive and Gram-negative bacteria, [19] and is therefore a useful broad-spectrum antibiotic.
Farinamycin is a quinazoline metabolite that has been isolated from Streptomyces griseus. It is the first known metabolite to be produced by S. griseus that is not a phenoxazinone antibiotic. Farinamycin is formed from the condensation of 3-OH-anthranalite and 3,4-AHBA building blocks that later combine with Enaminomycin C biosynthetically.

In this phylum, Streptomyces is the largest genus of bacteria, and are often associated with MHBs. [1] Streptomyces have been a model organism of study in biological research on MHBs. In one study, it has been reported that Streptomyces are responsible for increasing root colonization, plant biomass growth, mycorrhizal colonization, and fungal ...
