Streptomyces griseus
Tweet ThisStreptomyces griseus is a member bacterial species of the genus Streptomyces and are commonly found in soil. It is also called Actinomyces griseus. It produces Streptomycin, which is an antibiotic drug, the first of a class of drugs called aminoglycosides to be discovered, and was the first antibiotic remedy for tuberculosis. And it is in our soil.
It’s function in the soil is to aid with fungi to identify fungi that can infect root hairs with beneficial hyphen.
A-factor homologs that have a γ-butyrolactone structure have receptors that are highly specific to aid in discriminating signals received from neighboring organism thus allowing the cell to recognize the neighbor as a member of its own species or not. This system is also useful in the survival of in the ecosystem because A-factor produced by a cell is received by several hyphen and can result in rapid sporulation of whole populations. The A-factor and its receptor system acts as a crucial switch for physiological and morphological differentiation.
