[Production of extracellular higher fatty acids by yeasts grown on hexadecanoic acid]. / Obrazovanie vnekletochnykh vysshikh zhirnykh kislot drozhzhami pri roste na geksadekane.

Production of exocellular higher fatty acids by Candida yeasts was studied during their growth in a mineral medium with hexadecane. The qualitative and quantitative composition of exocellular higher fatty acids was investigated during cultivation of Candida lipolytica VCM Y 2378(695) under the conditions of different aeration (5 and 80% saturation of the medium with oxygen). Palmitic (C16:0), palmitooleic (C16:1), oleic (C18:1) and linoleic (C18:2) acids predominated among other higher fatty acids. The overall amount of fatty acids increased and the content of unsaturated fatty acids decreased when the yeast growth was limited with oxygen.
