摘要：
Microorganisms react upon hyperosmotic stress by accumulating compatible solutes. Here we report that Lactococcus lactis uses a transport system for glycine betaine that, contrary to earlier observations (D. Molenaar ct al., J. Bacteriol. 175:5438-5444, 1993), is osmotically regulated at the levels of both expression and transport activity.
