Effects of FLG and FLA on the microbial population in an in vitro fecal fermentation for (A) 12 h and (B) 24 h. Differences (Δ%) in the relative bacterial population sizes with respect to the total number of bacteria were evaluated after fermentation of FLG and FLA from green tea extract. The following calculation was applied: [(selected bacterial number at 12 or 24 h/total bacteria number at 12 or 24 h) – (selected bacterial number at 0 h/total bacteria number at 0 h)] × 100. NS stands for no substrate as a control. Different lowercase letters on the bars of each microorganism represent significant differences according to the Tukey–Kramer honest significant difference test (p < 0.05).
