Popis: | Data are presented showing that a large proportion of the fatty acids of Bdellovibrio bacteriovorus grown intraperiplasmically are derived unaltered from the fatty acids of its substrate organism. Those fatty acids of the bdellovibrio not homologous with those of the substrate organism are derived mainly by metabolic alteration of preexisting fatty acids in the latter. De novo synthesis from acetate occurs only to a small extent. These characteristics of bdellovibrio physiology are in part responsible for its minimal energy expenditure for intraperiplasmic growth. The data presented also indicate that B. bacteriovorus is capable of hydrogenating unsaturated fatty acids, of beta-oxidation of fatty acids, and of regulating the proportion of saturated and unsaturated fatty acids in the lipids. |
