Fatty acid composition of Turbatrix aceti and its culture medium

Abstract

1. 1. Turbatrix aceti propagated axenically at 30°C contained about 24 per cent lipid on a dry weight basis of which slightly over one-half was fatty acids. 2. 2. Of the 31 fatty acids identified oleic plus vaccenic acids, present in equal quantities, accounted for 25–34 per cent of the total fatty acids, and stearing plus linoleic accounted for another 24 per cent. 3. 3. About 65 per cent of the total amount of fatty acids was unsaturated. 4. 4. Beef liver extract in the medium was the major source of dietary fatty acids of which only two, 16:1 ω7 and 18:3 ω3, were present in sufficient quantities to account for the amounts of these fatty acids occurring in the nematodes; the major fatty acids of liver extract were palmitic, stearic, oleic and linoleic.
