Abstract
Henneman, DorothyH. (Rutgers, The State University, New Brunswick, N.J.),and W. W. Umbreit. Factors which modify the effect of sodium and potassium on bacterial cell membranes. J. Bacteriol.87:1266–1273. 1964.—Suspensions ofEscherichia coliB, when placed in 0.2 to 0.5msolutions of NaCl, KCl, or LiCl, show an increased turbidity. With NaCl, this increased turbidity is stable with time; with KCl and LiCl, it is gradually lost. The stability to NaCl with time is due to substances removable from the cell by incubation in phosphate buffer; these materials exist in water washings from such phosphate-incubated cells.Keywords
