摘要
Mycobacterium smegmatis is a commonly used mycobacterial model system. Here, we show that M. smegmatis protects itself against elevated salinity by synthesizing ectoine and hydroxyectoine and characterize the phenotype of a nonproducing mutant. This is the first analysis of M. smegmatis halotolerance and of the molecular mechanism that supports it.
