Effect of dilution of GuSCN solution on microbial composition in fecal samples. (a) Microbial composition at the phylum level for feces in GuSCN solution diluted with PBS; Aliquots (0.1 g) of fecal samples were in 15 ml vials containing 1 ml of GuSCN solution with 0, 0.1, or 1.0 ml of PBS. DNA was extracted within 3 days or after storage for one month at room temperature. (b) Abundance of various Proteobacteria at the class level in fecal samples after storage for one month at room temperature.
