title: INFLUENCE OF THE PHYSICAL STATE OF THE BACTERIAL CELL MEMBRANE UPON THE RATE OF RESPIRATION.
abstract: Henneman, Dorothy H. (Rutgers, The State University, New Brunswick, N.J.), and W. W. Umbreit. Influence of the physical state of the bacterial cell membrane upon the rate of respiration. J. Bacteriol. 87:1274-1280. 1964.-NaCl and KCl in concentrations of the order of 0.2 to 0.5 m inhibit the respiration of Escherichia coli B and other gram-negative organisms. Cell-free enzymes concerned in respiration and prepared from the same organisms are not inhibited by these salts, whereas these same enzymes tested in intact cells are. The physical state of the cell membrane appears to be a factor controlling its respiratory activity.
