Regulation of cytotoxicity by quorum-sensing signaling in Vibrio vulnificus is mediated by SmcR, a repressor of hlyU.

abstract：:The induction of paraffin oxidation in intact cells of Pseudomonas aeruginosa was investigated. Oxidation of (14)C-heptane by cell-free extracts of adapted cells showed that the activity of whole cells is a reliable reflection of the synthesis of the first enzyme in the degradation of n-alkanes.
