  6. Hydrogen sulfide (H2S) is produced by Escherichia coli cells growing in a synthetic minimal medium containing thiosulfate as a sole inorganic sulfur source, but not in a medium only containing sulfate. E. coli generated H2S in a DNA-binding transcriptional dual regulator CRP-dependent manner as a response to glucose starvation.

  7. Escherichia coli deletion mutants lacking cAMP-receptor protein (CRP) maintains colony-forming activities even after a long period of starvation, while wild-type cells lost most of this activity. The lack of cAMP-CRP effectively retains high colony-forming activities, indicating that cAMP-CRP acts as a positive regulator necessary for the induction of the viable but non-culturable state in E. coli.
