The effect of pyridoxine deficiency on fat metabolism was studied using mutant strains of Aspergillus nidulans requiring pyridoxine for growth. Under pyridoxine deficiency the mutants exhibited increased levels of total lipid, sterols, phospholipids, and triacylglycerols. Total fatty acids were found to decrease with pyridoxine deficiency. An increase in saturated fatty acids and decrease in unsaturated fatty acids were seen with deficiency. Pyridoxine deficiency also increased lower carbon chain fatty acids. A possible involvement of pyridoxine in the elongation of fatty acid chain and in the desaturation of fatty acids in Aspergillus nidulans is suggested.
