55 results about "Micromonospora" patented technology

Micromonospora is a genus of bacteria of the family Micromonosporaceae. They are gram-positive, spore-forming, generally aerobic, and form a branched mycelium; they occur as saprotrophic forms in soil and water. Various species are sources of aminoglycoside antibiotics with spellings that end with -micin, such as gentamicin, unlike most other aminoglycoside names that end with -mycin (e.g. neomycin and streptomycin and are produced by Streptomyces spp.).
