• 1E. cloacae strain E010 was cultured in King’s medium B (KB, 75 ml) mixed with different substrate (150 ml) in a moist chamber along with citrus fruit inoculated with P. digitatum for 7 days at room temperature. • 2Medium control contained medium ingredients without adding substrates. • 3H2O control (75 ml distilled H2O) contained no substrate and medium ingredients. • 4Means (n = 10) in the same column followed by the same letter are not significantly different according to nonlinear regression and Durbin-Watson Statistic normality tests (P = 0.05).
