Abstract
The molds Aspergillus nidulans, Penicillium frequentans, and Fusarium lycopersicum were tested for lipid production when grown on a deproteinized whey medium. F. lycopersicum produced highest total lipid (38.56%) followed by A. nidulans LC‐1 (16.90%) and P. frequentans (10.53%). Triglycerides and phospholipids were the predominant components in the neutral lipid fraction followed by partial glycerides, free fatty acids and nonsaponifiable matter. Phospholipid content was highest in P. frequentans. Palmitic, stearic, oleic and linoleic acids were the major fatty acids and their relative concentrations varied among the three fungi. Lower chain fatty acids were absent.
