Inorganic phosphate taken up was rapidly esterified to nucleoside triphosphates and diphosphates. Respiration and phosphate transport showed cooperative responses to Na+ which increased with temperature. Respiration was more sensitive to polymyxin B in the presence of Na+. Dinitrophenol and carbonyl cyanide p-trifluoromethoxy-phenylhydrazone stimulated respiration when either Na+ or K+ was absent, but not in the presence of both cations. Therefore, Na+ is essential for the cytoplasmic membrane of P. stutzeri to perform energy-linked functions coupled to respiration. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-98-2-503
