title: [Fatty acid makeup of Escherichia coli cells with repressed and derepressed phosphohydrolase biosynthesis].
abstract: Fatty acid composition of the cells of Escherchia coli wild strains K-10, and K-12 and the mutants of the regulatory genes for alkaline phosphatase was studied in conditions of repression and derepression of biosynthesis of phosphohydrolases. Derepression of phosphohydrolases was not accompanied with specific changes in fatty acid composition of the cells. An increase in the content of cyclopropanic acid in conditions of phosphorus deficiency and a decrease in the level of unsaturated fatty acids are related to deceleration of growth of the cells in these conditions.
