  1. All data were calculated based on 48 h of fermentation. Values indicate mean ± standard deviation of three biological replications. Statistical significance was determined using an independent samples t test. Difference is indicated as significant (*p < 0.05, **p < 0.01, and ***p < 0.001) when compared to the control strain KF-7. Difference is indicated as significant (#p < 0.05) when compared to the control strain E-158
