Figure 1From: Novel monosaccharide fermentation products in Caldicellulosiruptor saccharolyticus identified using NMR spectroscopySpectra illustrating selected identified compounds in cell extracts and supernatants. Black line represents extract spectral line, red represents supernatant spectral line. Panel A (mannose substrate) shows peak for hydroxyacetone (singlet at 4.368ppm, not in Chenomx database) present in supernatant (red) and not in extract (black). Panel B (L-arabinose substrate) shows methyl doublet for acetoin (1.368 ppm) present in supernatant (red) but not cell extract (black). Panel C (D-arabinose substrate) shows ethylene glycol present in both supernatant (red) and extract (black), and Panel D (L-fucose substrate) shows propylene glycol present in both supernatant (red) and extract (black).Back to article page
