Abstract:
Halomonas sp.BYS-1 was a moderately halophilic bacteria strain isolated from activated sludge,It could grow on MM with NaCl concentration from 0.1～2.6 mol/L and phenyl acetic acid as sole carbon souce. When BYS-1 grew in the media with different concentrations of NaCl, there was no obvious change in its intracellular Na+ contents , it accumulated K+, glutamic acid and betaine as osmoprotectants. Its intracellular contents of K+,glutamic acid and betaine increased by 1.9,2.4 and 13.6 times, respectively, when the concentration of NaCl increased from 0.1 mol/L to 2mol/L.
