[Lipid composition of certain predatory species of fungi of the genus Arthrobotrys].

The aim of this work was to study the effect of the composition of the medium on the biosynthetic activity of fungi belonging to the genus Arthrobotrys, the content of different lipid fractions in them, and their fatty acid composition. The following fractions typical of the majority of microbial species were found in the lipid composition of these predaceous fungi: phospholipids, monoglycerides, diglycerides, sterols, free fatty acids, and triglycerides. The fungi were capable of accumulating from 2.

[Age changes in the lipid fatty acid makeup of cultures of the family Entomophthoraceae].

The rate of biosynthesis of lipids and their fatty acid composition were studied in four cultures of microscopic fungi belonging to the family Entomophthoraceae in the course of their growth. The cultures synthesized from 23% to 43% of lipids. The lipids comprised fatty acids containing from 9 to 24 carbon atoms in the chain.
