Abundance of bacterial population through COS treatment.

COS Concentration [g L-1]	Log10 [Bacteria 16S rRNA gene (copies mL-1)]
	Inocula	8 h	72 h
0	11.32 ± 0.07	11.54 ± 0.08a	12.30 ± 0.08ab
0.1		11.10 ± 0.1b	12.35 ± 0.08a
1		9.02 ± 0.1c	12.27 ± 0.07ab
3		8.44 ± 0.1d	12.12 ± 0.06b

Abundance of bacteria was estimated by quantitative PCR analyses based on bacteria 16S rRNA gene copy numbers in the liquid medium containing mice feces treated with 0, 0.1, 1, or 3 g L^-1 COS, respectively. Data were collected at 0, 8, and 72 h of the treatment. Data are represented as the means ± SD (n = 3). Superscripts with different letters indicate significant differences (P < 0.05) between treatments at the same time point.
