2.8. Statistical analysis
All experiments were executed independently three times.
Microbial counts (cfu/g) were log transferred before statistical
analysis. The data were given as means ± standard deviations. All
data were statistically analyzed by ANOVA using SPSS 17.0 for
windows (SPSS Inc, Chicago, IL, USA). Multiple comparisons of
means were done using least significant difference (LSD) at 5%
significance level (P < 0.05).
