Monovalent cations enable cell wall turnover of the turnover-deficient lyt-15 mutant of Bacillus subtilis

A lyt-15 mutant reported to be unable to turn over the cell wall exhibited the same rate of wall turnover as the standard strain if the medium contained 0.2 M NaCl, which did not affect growth. Cell wall autolysis was also optimal at 0.2 M NaCl.
