Abstract The metabolism of fatty acids and methyl ketones by Penicillium roqueforti was studied in phosphate buffered solutions and buffered solutions with added soluble casein. It was found that casein enhanced the metabolism of fatty acids and the quantity of methyl ketones produced. Methyl ketones were also found to be metabolised by P. roqueforti in phosphate buffered solutions. The addition of fatty acids inhibited the metabolism of the ketones. The inhibitory effects of the fatty acids were nullified in the presence of casein hydrolysate.
