Where T0 = Control, T1 = B. cereus, T2 = Cr-20 mg/kg, T3 = Cr-20 mg/kg + B. cereus, T4 = Cr-30 mg/kg, T5 = Cr-30 mg/kg + B. cereus, T6 = Cr-40 mg/kg, T7 = Cr-40 mg/kg + B. cereus. Values are mean of replicates, standard deviations is also calculated and different letters indicate significant differences between means of treatments at p < 0.05 according to LSD test.
