Abstract Background The survival of bacteria largely depends on signaling systems that coordinate cell responses to environmental cues. Previous studies on the two-component ColRS signal system in Pseudomonas putida revealed a peculiar subpopulation lysis phenotype of colR mutant that grows on solid glucose medium. Here, we aimed to clarify the reasons for the lysis of bacteria. Results We present evidence that the lysis defect of P. putida colR mutant is linked to hunger response. A subpopulation prone to lysis was located in the periphery of bacterial cultures growing on solid medium. Cell lysis was observed in glucose-limiting, but not in glucose-rich conditions. Furthermore, lysis was also alleviated by exhaustion of glucose from the me...
