Starvation/stationary-phase survival of Rhodococcus erythropolis SQ1: a physiological and genetic analysis.

The adaptation of Rhodocccus erythropolis SQ1 to energy and carbon starvation was investigated in terms of both the capacity to survive starvation and the contribution of a nutrient-induced stationary phase to cross-protection to other types of environmental stress. It was found that R. erythropolis SQ1 survives for at least 43 days in LB and distilled water, and 65 days in chemically defined medium (CDM) containing high (1%) or low (0.
