Autolysis of microbial cells: salt activation of autolytic enzymes in a mutant of Staphylococcus aureus

Autolysis of microbial cells: salt activation of autolytic enzymes in a mutant of Staphylococcus aureus

R W Gilpin et al. J Bacteriol. 1972 Jul.

Abstract

The effect of various salts on the autolysis of cell wall of a ribitol teichoic acid-deficient mutant of Staphylococcus aureus H (strain 52A5 carrying tar-1) was compared with the parent strain. In the presence of high concentrations of certain salts such as 1.0 m NaCl, the mutant undergoes autolysis with the release of osmotically sensitive spheroplasts. The parent strain is not affected by these conditions. The stimulation of lysis is related to an activation of N-acylmuramyl-l-alanine amidase.
