The Pseudomonas fluorescens Crc affects the length of the transition phase during diauxic growth

ABSTRACT: Pseudomonads, unlike enteric bacteria, prefer to utilize tricarboxylic acid cycle intermediates over glucose. The crc gene has been implicated to impart repression on glucose and other metabolic enzymes in various Pseudomonas species when grown in a mixture of glucose and various organic acids. The crc gene of P. fluorescens strain MB101 has been identified and a crc deletion derivative was constructed. Unlike a crc mutant of P. aeruginosa described earlier, the P. fluorescens crc did not begin to catabolize glucose until most of the succinate has been utilized in a medium containing both carbon sources. The transition phase during diauxic growth in succinate/glucose media was found to be shorter in a strain lacking crc and considerably longer in a strain overproducing Crc as compared
