  1. Group A represents the control flask experiment without HAP and the strain; group B represents the flask experiment with 3% HAP; group C represents the flask experiment with the strain (108 cells/mL); and group D represents the flask experiment with the SH. Each group was replicated three times. According to ANOVA (Tukey’s test), there is no significant difference in the value of the same letter within a single column at p < 0.05 (Significant at 95% confidence interval, F: statistics, df: degrees of freedom).
