| Chemical Properties | Back Directory | [Definition]
An antibiotic isolated from products of Strepto-
myces halstedii when grown in suitable media
by the deep-culture method. It inhibits growth of
certain gram-positive bacteria such as staphylo-
cocci, pneumococci, and hemolytic streptococci.

A selected strain of Streptomyces halstedii was cultivated in an aqueous
nutrient medium under aerobic conditions and the resulting broth containing
carbomycin antibiotics was filtered. The solutions was extracted twice at pH
6.5 with one-quarter volume of methyl isobutyl ketone. The combined extracts
were concentrated to one-tenth volume under vacuum, and the antibiotics
were extracted into water adjusted to a pH of about 2 with sulfuric acid. After
adjusting the separated aqueous solution to pH 6.5, the antibiotic was
extracted into benzene and the solution was concentrated to a small volume.
Addition of hexane resulted in the separation of a solid product containing the
benzene complexes of carbomycin A and carbomycin B, present in the
fermentation broth. | [Therapeutic Function]
