Figure 2From: Proteins involved in difference of sorbitol fermentation rates of the toxigenic and nontoxigenic Vibrio choleraeEl Tor strains revealed by comparative proteome analysis1H-NMR spectra of JS32 and N16961 sorbitol fermentation medium. Samples were collected at four time points: the starting time (0 h), the JS32 color change (4 h), the N16961 color change (8 h), and 24 hours. Formate could be seen at 4 h in JS32, while there was no formate peak in N16961.Back to article page
