The lipopolysaccharides of Rhodospirillum rubrum, Rhodospirillum molischianum, and Rhodopila globiformis

Archives of Microbiology, 1990
The cell wall lipopolysaccharides from three phototrophic species of the alpha1-group of Proteobacteria, Rhodospirillum rubrum, Rhodospirillum molischianum, and Rhodopila globiformis were isolated and chemically characterized. Sodium deoxycholate polyacrylamide gel electrophoresis patterns revealed that the lipopolysaccharides of all three species ...

Chromatophores of Rhodospirillum rubrum

Nature, 1952
THE pigments of pbiotosynthetic bacteria are not localized in chloroplasts, and appear upon microscopic examination to be evenly distributed throughout the cell. It has long been known that the absorption maxima of the bacteriochlorophyll and carotenoid pigments are markedly shifted following extraction with organic solvents—a fact first interpreted by

Transamination in Rhodospirillum rubrum

Archives of Biochemistry and Biophysics, 1957
Abstract Whole cell and cell extracts of Rhodospirillum rubrum grown in the dark or light contain transaminases which catalyze the formation of glutamate from α-ketoglutarate and the following amino acids: phenylalanine, aspartate, tyrosine, ornithine, valine, leucine, isoleucine, tryptophan, histidine, and alanine.

COMPARATIVE STUDIES WITH THE PHOTOOXIDASE OF RHODOSPIRILLUM

Canadian Journal of Microbiology, 1961
When heterotrophically grown Rhodospirillum rubrum was reincubated anaerobically in the light, the photosynthetic growth resulted in a simultaneous appearance of the photosynthetic pigments, photooxidation, and photophosphorylation. Addition of exogenous diphosphopyridine nucleotide to extracts of photosynthetically grown cells inhibited photooxidation

Rhodospirillum sodomense, sp. nov., a Dead Sea rhodospirillum species

Archives of Microbiology, 1993
A new species of halophilic anoxygenic purple bacteria of the genus Rhodospirillum is described. The new organism, isolated from water/sediment of the Dead Sea, was vibrio-shaped and an obligate halophile. Growth was best at 12% NaCl, with only weak growth occurring at 6% or 21% NaCl.
