Effects of growth inhibition by B. adolescentis SPM0212 on colon cancer cell lines (Caco-2, HT-29 and SW480). The cells (1 × 10³ cells/well) were treated with B. adolescentis SPM0212 butanol extract (25, 50, 100, 200 μg/ml), and incubated for 72 hr at 37°C and 5.5% CO₂. After adding 50 μl of the XTT labeling mixture, they were incubated for 6 hr at 37°C in 5.5% CO₂. The absorbance was measured using an ELISA reader at 490 nm. The quantitative data were presented as means ± SD of three independent experiments. Control versus treatment groups, *p < 0.05; **p < 0.01.
