Racemization of lysine by a pseudomonad.
The recent paper by Huang and Davisson (J. Bacteriol., 76, 495, 1958) on the distribution of lysine racemase in bacteria reports its occurrence in only a few species of Escherichia and Proteus. Various other bacteria including 22 strains of various genera of the Pseudomonadaceae did not possess such activity. I wish to report evidence for the occurrence of lysine racemase activity in a Pseudomo...
متن کاملPhenazine biosynthesis by a pseudomonad.
The acidophilic bacterium Pseudomonas phenazinium (N.C.I.B. 11027), isolated from soil by virtue of its ability to grow on L-threonine as sole source of carbon and nitrogen (Bell et al., 1972), was observed to produce the water-insoluble purple pigment iodinin (phenazine-l,6-diol 5,lO-dioxide) during growth on L-threonine or glycine media (Bell & Turner, 1973). Evidence was obtained that iodini...
متن کاملMetabolism of imidazole by a pseudomonad.
Intermediates formed during the microbial degradation of imidazole, namely 4(5)-imidazolone, formiminoglycine, and possibly glycine, are similar to those formed during metabolism of imidazole derivatives.
متن کاملDegradation of triphenyltin by a fluorescent pseudomonad.
Triphenyltin (TPT)-degrading bacteria were screened by a simple technique using a post-column high-performance liquid chromatography using 3,3',4',7-tetrahydroxyflavone as a post-column reagent for determination of TPT and its metabolite, diphenyltin (DPT). An isolated strain, strain CNR15, was identified as Pseudomonas chlororaphis on the basis of its morphological and biochemical features. Th...
متن کاملThe metabolism of nitrilotriacetate by a pseudomonad.
1. An organism that grows on nitrilotriacetate as sole source of carbon and energy was isolated in pure culture and was identified as a pseudomonad. 2. Cell-free extracts of the nitrilotriacetate-grown pseudomonad contain an enzyme that catalyses the NADH-and O(2)-dependent oxidation of nitrilotriacetate to iminodiacetate and glyoxalate. This enzyme is absent from extracts of glucose-grown cell...
