Abstract Comparison of the effects of uncoupling agents, arsenate, fluoride and cyanide on sugar transport byThiobacillus A2 indicated that (a) glucose uptake by fast-growing strain GFI involved a high energy phosphate dependent system; (b) transport of glucose by the wild type and of fructose and sucrose by both strains, was by respiration dependent systems requiring a membrane proton gradient. Glucose and sucrose were competitive inhibitors of the transport of each other. Bacteria grown on glucose +sucrose (20+2 mM) transported glucose much faster than those grown on glucose alone. This could explain the great stimulation of growth rate on glucose, in the presence of sucrose.
