Notes:
Abstract Vegetable oils promoted mycelial growth ofVolvariella volvacea. Ethyl esters of major components of saponified fatty acids (palmitic, stearic, oleic and linoleic acid) from vegetable oils were stimulatory. The stimulatory effect of these fatty acids varied with concentration and degree of unsaturation; relatively high concentrations being inhibitory. Mycelial growth appears to be promoted by low concentrations of fatty acids. Supplementation of growth medium with sunflower oil altered membrane permeability and this resulted in an increased uptake of glucose. The total mycelial lipids accounted for only 30% of consumed lipids, the remainder being metabolized. The failure of the fungus to adjust the degree of unsaturation in membrane lipids when it was transferred to 0°C may partially explain its susceptibility to chilling injury.
