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. ...
متن کاملDevelopment of a vector and host system and characterization of replication of plasmid pSQ10 in moderately halophilic Nocardiopsis.
The genus of Nocardiopsis is a new source of antibiotics, chemicals, and enzymes. Here we reported the development of a vector and host system in moderately halophilic Nocardiopsis via an oriT-mediated conjugation. By screening about 80 Nocardiopsis strains, 6 of them harbored 8 plasmids (18-80 kb). The complete nucleotide sequence of pSQ10 consisted of 18,219 bp, with 71.9% G + C content, enco...
متن کاملBiology of moderately halophilic aerobic bacteria.
The moderately halophilic heterotrophic aerobic bacteria form a diverse group of microorganisms. The property of halophilism is widespread within the bacterial domain. Bacterial halophiles are abundant in environments such as salt lakes, saline soils, and salted food products. Most species keep their intracellular ionic concentrations at low levels while synthesizing or accumulating organic sol...
متن کاملBetaine is the main compatible solute of halophilic eubacteria.
A number of moderately halophilic bacteria of diverse taxonomic groups have been studied to determine the intracellular concentrations of organic compounds at various salt concentrations. Betaine was accumulated in all of these organisms in proportion to the salinity of the medium, suggesting that this compound plays a major role in osmoregulation.
متن کاملIsolation and Characterization of a Moderately Halophilic Protease Producing Pseudomonas Sp. from Brine Samples of a Coastal Area Solar Saltern
Screening of the brine samples of a solar saltern has yielded one moderately halophilic protease producing bacteria. The bacterial isolate has been identified as a Pseudomonas sp. and it produced an extracellular protease and an amylase. Maximal protease production was detected at the early stationary phase. The enzyme showed the highest activity at 400C and pH 8.0 in 15% NaCl. The enzyme was a...
