The statistical analysis showed a significant difference (P < 0.05) between the treated samples and the control, in both at 0 (zero) and at 10 day (Table 1). However, no significant difference (P > 0.05) was found between the treated samples at 0 (zero) time and 10 day, 1.5 log cfu/g ` 1.37 and 2.7 log cfu/g ` 0.64, respectively.
