RESUMO
The induction of D-xylose, D-ribose, L-arabinose, and D-lyxose isomerases by various sugars was studied to determine the configuration necessary for induction. D-Xylose isomerase was only induced by D-xylose, whereas D-ribose isomerase was induced by D-ribose, L-rhamnose, and L-lyxose. L-arabinose isomerase was induced by L-arabinose, D-galactose, L-arabitol, D-fucose, and dulcitol, whereas D-lyxose isomerase was induced by D-lyxose, D-mannose, D-ribose, dulcitol, and myoinositol. Some compounds such as dulcitol, D-galactose, and D- or L-fucose which do not support growth are still able to serve as inducers for various pentose isomerases.
