  • Lipid composition of Aspergillus niger in citric acid accumulating and nonaccumulating conditions
    Jernejc, Katarina ; Vendramin-Pintar, Mateja ; Cimerman, Aleksa
    A comparative study of the lipid composition of Aspergillus niger mycelia was done. The amount of total lipids in mycelia grown in the presence of maganese was up to two times higher than in ... conditions favoring citric acid accumulation (Cu [up]2+ present). Among individual lipid classes, the amounts of phospholipids and neutral lipids were lower under manganese deficiency. Regarding phospholipid composition, phosphatidylethanolamine and diphosphatidylglycerol prevailed under citirc acid accumulating conditions, whereas under restricted citric acid biosynthesis, phosphatidylcholine was present in larger amonts. Regarding the fatty acid composition, unsaturated acids predominated in all mycelial samples tested. The ratio of saturated to unsaturated acids was always lower in accumulating conditions. There was more linoleic acid and less palmitic and stearic acid when citrate was accumulated.
