title: [Phosphate and glucose accumulation by Pseudomonas cultures in relation to their arsenic resistance].
abstract: The effect of arsenite and arsenate on 14C-glucose and 32-P-phosphate transport was studied in the cells of Pseudomonas aeruginosa 561 sensitive to arsenite and in the cells of Pseudomonas putida 18 oxidizing arsenite and resistant to arsenic. Transport and accumulation of phosphate and glucose were inhibited in the presence of arsenite in the cells of P. aeruginosa 561 whereas arsenate inhibited only phosphate accumulation. Arsenite and arsenate had hardly any effect at the initial transport rate and on the overall accumulation of phosphate and glucose in the cells of P. putida 18. The resistance to arsenite is supposed to be caused by selective impermeability of the cellular membranes to arsenite and arsenate.
