Anaerobic phycomycete fungi were found in gut and faecal samples from sheep, cattle, goat, sika deer, Japanese serows, the musk ox, horses and ponies. The population size of the fungi estimated by the roll tube method was of the order of 103/ml for the gut samples and 102/g for the faecal samples. A Neocallimastix sp. and a Piromyces sp. were isolated from sheep rumen samples and a Caecomyces sp. from horse faecal samples. The chemical composition of these isolates was examined: there were no distinct differences in amino acid and fatty acid composition among the three isolates, and the amino acid composition was similar to that of rumen protozoa. The fatty acid composition of the isolates was rich in long-chain fatty acids, especially in oleic acid, which amounted to 45% of total fatty acids (w/w) in the lyophilized samples of the Piromyces sp. The isolates all contained chitin ranging from 3.4% (Piromyces sp.) to 4.3% (Caecomyces sp.).
