Chromohalobacter nigrandesensis sp. nov., a moderately halophilic, Gram-negative bacterium isolated from Lake Tebenquiche on the Atacama Saltern, Chile.
A total of 52 strains of moderately halophilic bacteria isolated from hypersaline sediment of Lake Tebenquiche on the Atacama Saltern, Chile, were subjected to a taxonomic study. The morphological, physiological, biochemical and nutritional characteristics of the strains matched those described for the genus Chromohalobacter. Cells were Gram-negative, non-spore-forming, rod-shaped and motile. A...
متن کاملGram-Negative Bacterium
The cell envelope of a marine pseudomonad as seen in thin section by electron microscopy has the double-membrane structure typical of other gram-negative bacteria. Cells washed with a solution containing Na+, K+, and Mg++ at their concentrations in the growth medium, when suspended briefly in 0.5 M sucrose, lost 13% of their hexosamine in a form nonsedimentable by centrifugation at 73,000 x g. ...
متن کاملParacoccus haeundaensis sp. nov., a Gram-negative, halophilic, astaxanthin-producing bacterium.
An aerobic, non-motile, Gram-negative, orange-pigmented, rod-shaped, astaxanthin-producing marine bacterium was isolated from the Haeundae Coast, Korea. This strain, BC74171T, produced carotenoids, mainly astaxanthin. All the type strains of the genus Paracoccus were compared with strain BC74171T using 16S rRNA gene sequence analysis, fatty acid patterns and physiological reaction profiles. Bas...
متن کاملTyrosine sulfation in a Gram-negative bacterium.
Tyrosine sulfation, a well-characterized post-translation modification in eukaryotes, has not previously been reported in prokaryotes. Here, we demonstrate that the RaxST protein from the Gram-negative bacterium, Xanthomonas oryzae pv. oryzae, is a tyrosine sulfotransferase. We used a newly developed sulfotransferase assay and ultraviolet photodissociation mass spectrometry to demonstrate that ...
متن کاملIsolation and chemical composition of the cytoplasmic membrane of a gram-negative bacterium.
With procedures developed previously in this laboratory, the various layers of the cell wall of a gram-negative bacterium, a marine pseudomonad (ATCC 19855), were removed completely giving rise to true protoplasts. Membranes were isolated from the protoplasts formed. After treatment with ribonuclease, deoxyribonuclease, and washing, the membranes isolated were shown by electron microscopy and c...
