All values are mean ± SD of three replicates.
For the same row, alphabets indicate significant difference (p < 0.05) (Duncan’s multiple t-test).
For the small letters within columns significant difference and (p < 0.05) (Duncan’s multiple t-test).
Transfer rate is expressed as the microbial reduction rate (%).
