title: Production of cyclochlorotine and a new metabolite, simatoxin, by Penicillium islandicum Sopp.
abstract: Production of the hepatotoxin cyclochlorotine by Penicillium islandicum was studied under a variety of fermentation conditions. The best system for production was agitated red wheat. A thin-layer chromatographic method was developed for the detection of this cyclic polypeptide. These experiments have resulted in the isolation of a new toxic metabolite, which we call simatoxin.
