  1. For each strain, 20–30 cells and 250–300 crystals were visualized and measured. a: there is significant difference between the mean crystal diameter of WT and ∆mamX (P < 0.01, by Student t-test); b: there is significant difference between the mean crystal number of WT and ∆mamX (P < 0.01, by Student t-test).
