A 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...

Halophilic nuclease from a moderately halophilic Micrococcus varians.

The moderately halophilic bacterium Micrococcus varians, isolated from soy sauce mash, produced extracellular nuclease when cultivated aerobically in media containing 1 to 4 M NaCl or KCl. The enzyme, purified to an electrophoretically homogeneous state, had both ribonuclease and deoxyribonuclease activities. The nuclease had maximal activity in the presence of 2.9 M NaCl or 2.1 M KCl at 40 C. ...

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...

Salt-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 ...
