~Streptomyces Griseus Basic information
So you wanna know more about Streptomyces Griseus, eh? Well, most likely you don't. But this is actually a fairly interesting bacteria, so sit down and read this for awhile!
Basic Information~
Streptomyces griseus is a gram-positive bacteria with a spirilla-like structure. It is spore-forming (that's how it reproduces), and it has no flagella. In depth, reproduction is basically sending out speciallized aerial branches which form the spores. The spores are paracitic of the colony (they live off of the colony). Streptomyces griseus is fairly fungi like and eats decaying material in the soil such as leaves and nutrients and is heterotrophic. It is aerobic and non-motile. Now brace yourself for a long thing about order and classification: Bacteria > Actinobacteria > Actinobacteria > Actinomycetales > Streptomycinae > Streptomycetaceae > Streptomyces > Griseus. And there you have it! It's melting point is twelve six degrees celsius and it's growing point is twenty-six degrees celsius, which means it can only grow as a liquid. It's biohazard level is 1, which means it is not that dangerous to humans (highest biohazard level is 4). It is found in the soil, busy eating decaying material and making the soil fertile. And tah-dah! Streptomyces in a nutshell!
History~
Streptomyces griseus has existed for around 450 million years ago, but it hasn't been noticed much until recently. Streptomycin is a very important antibiotic produced by streptomyces griseus. It was first isolated by scientist by the name of Albert Schatz on October 19, 1943. ISchatz was a graduate student in a labratory of Selman Abraham Waksman at Rutgers University. He also discovered many other antibiotics such as actinomycin, clavacin, streptothricin, and many more. This drug was the first drug able to work against tuberculosis, and its production was managed and dominated by Merck & Co. under George W. Merck.
Uses~
Streptomyces griseus is a very helpful bacteria. Streptomycin is probably its most important antibiotic. To view more information on streptomycin, you may want to click this link. Another important substance is streptocin. This is an anti-cancer drug. Its name comes from "strepto" meaning twisted and "mukes" meaning fungus (Greek).
