The composition of the fatty acid profiles of Cl. perfringens type A, grown on media with initial pH values from 5.5 to 9.0, was determined by the method of gas-liquid chromatography. The fatty acid profiles are stabilized in 18- to 24-h cultures. Hydrogen ions stimulate the synthesis of cyclopropane carboxylic fatty acids and "desaturase" activity; hydroxyl ions inhibit these processes. The content of saturated fatty acids in the bacteria is regulated by the initial acid-alkaline conditions of the medium. An increase in biomass accumulation under the influence of hydroxyl ions is coupled with a decrease in the energy supply of the bacteria. Possible mechanisms of the development of resistance to hydrogen and hydroxyl ions during the cultivation of Clostridia on a period growth medium are discussed.
