Uptake of D-xylose and D-glucose by Spirochaeta aurantia

Uptake of D-[14C]glucose and D-[14C]xylose by Spirochaeta aurantia was demonstrated to be osmotic shock sensitive and to require a high-energy phosphorylated compound rather than a proton motive force. These features are similar to those of binding protein-mediated transport systems in other gram-negative bacteria.
