✦ Synopsis
Incorporation of organic compounds into cell protein by the obligate chemolithotrophs Nitrosomonas spec., Nitrosococcus oceanus, Nitrosococcus mobilis, Nitrosovibrio tenuis, Nitrosolobus spec., and Nitroso~pira spec. was studied. In the presence of ammonia as energy source organic substrates were supplied. Distribution of I4C into cell amino acids arising from 14C-labelled glucose, Napyruvate, and Na-acetate was investigated. While carbon from glucose was distributed unrestricted, carbon from pyruvate preferably entered into the amino acids of the pyruvate and glutamate family and from acetate mainly into leucine and the glutamate family. Among the strains examined, slight differences were observed, but all should be included under group A of the scheme of Smith and Hoare (1977).
