    Geotrichum candidum 4013: Extracellular lipase versus cell-bound lipase from the single strain

  • Original language description

    Two types of lipases (extracellular and cell-bound) were produced by Geotrichum candidum 4013 in liquid medium and were used as biocatalysts in blackcurrant oil hydrolysis. Reaction products were analysed for the degree of conversion from which enzyme activity was evaluated, and the composition of free fatty acids was compared to the composition of oil substrate. The enzyme activity was measured also before and after the reaction in SC-CO2. The fatty acid composition of the acids liberated from oil by hydrolysis suggests a specificity of the cell-bound and extracellular enzymes from Geotrichum candidum 4013. The extracellular lipase displays low selectivity to the polyunsaturated fatty acids, and the cell-bound lipase possesses selectivity to the saturated fatty acids. Enantioselectivity of the tested processes achieved with both induced enzymes was high (from 43 to 242). The activity of all enzymes has markedly increased after their exposure to SC-CO2. The treatment of enzymes by SC-C
