- Sporulation frequency (%) is calculated by counting spores and vegetative cells in randomly selected different views. (−) Not tested. More than 300 cells were counted and classified into spores and vegetative cells. For 1b and 3, sporulation assays were repeated trice to confirm their reproducible sporulation inducing activities
