Lentibacillus salis sp. nov., a moderately halophilic bacterium isolated from a salt lake.
A Gram-positive, moderately halophilic bacterium, designated strain BH113T, was isolated from a salt lake located in Xinjiang Province, China. Cells of the strain were aerobic, spore-forming, motile rods with flagella. The organism grew optimally at 37 degrees C and pH 8.0 in the presence of 10 % (w/v) NaCl. A phylogenetic analysis based on comparisons of 16S rRNA gene sequences showed that the...
متن کاملA salt-inhibited cytochrome c reductase obtained from the moderately halophilic bacterium, Micrococcus halodenitrificans.
A membrane-bound cytochrome c reductase from Micrococcus halodenitrificans was inhibited by NaCl at concentrations as low as 0.05 m. The inhibition was competitive with respect to cytochrome c and noncompetitive with respect to reduced nicotinamide adenine dinucleotide. Thus the effect of NaCl was to increase the apparent K(m) of the enzyme for cytochrome c and not to inhibit the intrinsic acti...
متن کاملSalt-inducible multidrug efflux pump protein in the moderately halophilic bacterium Chromohalobacter sp.
It has been known that halophilic bacteria often show natural resistance to antibiotics, dyes, and toxic metal ions, but the mechanism and regulation of this resistance have remained unexplained. We have addressed this question by identifying the gene responsible for multidrug resistance. A spontaneous ofloxacin-resistant mutant derived from the moderately halophilic bacterium Chromohalobacter ...
متن کاملDraft Genome Sequence of Staphylococcus succinus Strain CSM-77, a Moderately Halophilic Bacterium Isolated from a Triassic Salt Mine
Here, we report the draft genome sequence of Staphylococcus succinus strain CSM-77. This moderately halophilic bacterium was isolated from the surface of a halite sample obtained from a Triassic salt mine.
متن کاملGracilibacillus orientalis sp. nov., a novel moderately halophilic bacterium isolated from a salt lake in Inner Mongolia, China.
Three Gram-positive, moderately halophilic, spore-forming rods, designated XH-63T, XH-62 and EJ-15, were isolated from two salt lakes located near Xilin Hot and Ejinor, in Inner Mongolia, China. The strains were strictly aerobic and motile, with spherical, terminal and deforming endospores. They grew at pH 5.0-9.0 (optimal growth at pH 7.5), between 4 and 45 degrees C (optimal growth at 37 degr...
