Pholipomycin, a new member of phosphoglycolipid antibiotics. I. Taxonomy of producing organism and fermentation and isolation of pholipomycin.

Pholipomycin is a new member of the phosphoglycolipid family of antibiotics. Taxonomic studies of the producing organism revealed that it has morphologically characteristic aerial mycelia in which two to three spores are borne usually on short and clavate side branches. The species name, Streptomyces lividoclavatus, has been proposed. Pholipomycin is produced mainly in the solid residue of the fermentation culture broth and is isolated by methanol extraction of the mycelial cake followed by purification on ion-exchange resin and silica gel chromatography.
