Na+-induced structural change of a soil bacterium, S34, and Ca2+ requirement for preserving its original structure.
A drastic change in the outer membrane structure of a salt-sensitive soil bacterium, S34, related to the genus Deinococcus was induced by 0.2 to 0.4% (wt/vol) NaCl. The change was relieved by 6 mM CaCl2 and induced by 1 mM EGTA. The results indicate the strong dependence of the organism on calcium.
