Determination of tea saponin degradation capacity of multistrain and single-strain cultures. (A) Tea saponin gradient plate depicting bacterial colonies isolated from the CW gut. (B) Identification of the bacteria isolated from tea saponin medium by phylogenetic analysis. (C) Phylogenetic tree for the bacteria isolated from tea saponin medium. (D) The capability of different cultures to degrade tea saponin as illustrated using HPLC measurements. Statistical analysis was conducted by one-way ANOVA, followed by a multiple-comparison test using least-significant difference (LSD) at a P value of <0.05. Bars marked with different lowercase letters are significantly different at a P value of <0.05.
