Table 1 Growth rates of C. salexigens wild type strain (CHR61) and mutant CHR95 on glucose and ectoines at different salinities

From: Involvement of EupR, a response regulator of the NarL/FixJ family, in the control of the uptake of the compatible solutes ectoines by the halophilic bacterium Chromohalobacter salexigens
