Abstract
A chloroform extract of the mycelium of Fusarium oxysporum Schl. em. Sny. et Hans, was analyzed for sterols; three major components were identified as ergosterol, ergosterol peroxide, and cerevisterol. The ratio of ergosterol to ergosterol peroxide formed was variable. Palmitic, stearic, oleic, and linoleic acids were identified by gas–liquid chromatography as the principal fatty acids of this organism.Fusaric acid, a phytotoxin previously obtained by other investigators from a number of forms of F. oxysporum, was isolated from the culture medium.
