  1. Estimated regression coefficients and p-values are reported for the study of ATc and HSL. Only sterile broth conditions were considered for HSL. The regression coefficients β (i.e., the coefficients that are multiplied by time) shown in bold are significantly different from zero (P < 0.05, t-test) and identify the main factors or interaction terms that significantly contribute to inducer decay.
