title: [Effect of limitation of bacterial growth with carbon, sulfur and iron on the synthesis of cytochromes, development of cyanide-resistant respiration and super-synthesis of metabolites].
abstract: The work is concerned with the effect produced by limiting the growth of various bacteria with carbon, sulfur and iron on cytochrome synthesis, development of cyanide-resistant respiration and oversynthesis of metabolites. The cessation of bacterial growth due to the exhaustion of a carbon source was shown to be accompanied with the development of cyanide-resistant respiration though the oversynthesis of metabolites did not occur. If the growth was limited by a sulfur or iron source, the concentration of cytochromes a, b and c fell down as compared with that when the growth was limited by a carbon source, and metabolites were produced and accumulated in the medium. In that case, the respiration of virtually all the bacteria was inhibited by cyanide to a great extent. As was demonstrated for Pseudomonas aeruginosa, the development of cyanide-resistant respiration was inhibited when metabolites accumulated and then the respiration became completely resistant to cyanide as soon as the oversynthesis ceased. Apparently, whatever limits the bacterial growth, the process of oversynthesis inhibits cyanide-resistant oxidase.
