Peculiarities of the fatty acid composition of Bdellovibrio.
The fatty acid composition of twelve Bdellovibrio strains isolated upon the growth on bacteria of various taxonomic groups was studied. A dependence of the lipid composition of bdellovibrios on that of bacteria they were parasitizing on was shown. Data pointing to the selective incorporation of fatty acids of host bacteria by bdellovibrios were obtained. Bdellovibrio membranes were shown to contain monounsatured fatty acids with different positions of double bonds indicating that there are at least two alternative mechanisms of synthesis of these acids in the parasites.
