To determine the regulating role of mtlR in transcription of mannitol PTS operon in V.cholerae,and whether it plays a role in the ferment difference of the toxigenic and non-toxigenic strains,the mtlR deletion mutants from the mannitol rapid-ferment strain(non-toxigenic strain) and slow-ferment strain were constructed.Comparisons of the growth in M9 containing 0.2% mannitol as the sole carbon source and pH change in mannitol fermentation media of these wild strains and their mutants,indicated that mtlR is a repressor.Its repression in mtlCBA transcription was further verified with the analyses of quantitative reverse-transcriptional PCR.
