Effect of P. fermentans YSH secretion metabolites on the viability of HSC4 cancer cells and KDR normal cell by 60 µL for 24 h incubation. Data are expressed as mean viability ± SD (error bars). Asterisks denote statistically significant differences (**p ≤ 0.01, *p ≤ 0.05). Untreated cells were used as negative control and cisplatin was used as a positive control. Yeast malt broth as yeast culture medium was used to determine its effect on cell viability. All experiments were performed independently in triplicate
