Fatty Acid Analysis of Anaerobic Ruminal Fungi Neocallimastix,Caecomyces and Orpinomyces

This study aimed to explore the fatty acid composition of the isolated ruminal fungi Neocallimastix, Orpinomyces and Caecomyces. Fatty acids of carbon chain lengths ranging from 12 to 24 were analyzed as methyl esters. Neocallimastix and Caecomyces had oleic acid (c18:1) as the major fatty acid, while Orpinomyces had equal concentrations of oleic (c18:1) and palmitic acid (c16:0). All fungal isolates had similar amounts of myristic (c14:0) and stearic acid (c18:0), although they showed various profiles for lauric (C12:0) and nervonic (C24:1) acids. © 2010 Friends Science Publishers
