Abstract
Improved process for the isolation of laidlomycin from a fermentation broth includes increasing the pH of the fermentation broth and centrifuging the pH adjusted fermentation broth, resulting in an aqueous layer and a wet solid layer containing laidlomycin. After the aqueous layer is removed, the wet solid layer containing laidlomycin is dried. The process provides an efficient and high yielding method.
