Samples of a lysis recording and frequency distributions of various experimental treatments. (A) Sample recordings from strain IN63. It takes about 5 sec for the upper left cell to disappear from view. (B) Sample frequency distributions of lysis times from strains IN56, IN67, IN68, SYP028, IN56 with KCN added at 55 min after thermal induction, and IN56 grown in glycerol minimal salts medium. The bin size was 2 min. Additional data are shown in Tables 1 and 2.
