The Growth of C. concisus under Anaerobic and Microaerobic Conditions Containing Different Concentrations of H2 \nP3UCO-S1 strain was used as a representative strain to evaluate the growth of C. concisus under anaerobic and microaerobic conditions containing different concentrations of H2. Under anaerobic conditions, the CFUs of P3UCO-S1 strain cultured in the presence of 2.5%, 5%, and 10% H2 were (1.10 ± 0.42) × 109/mL, (9.15 ± 0.82) × 109/mL, and (1.90 ± 1.33) × 109/mL, respectively. The CFU numbers of 5% H2 were significantly higher than the CFU number of 2.5% and 10% H2 (both P \u003c 0.0001). The CFU numbers of 10% H2 and 2.5% H2 were not significantly different (P = 0.3) (Figure 1).\nUnder microaerobic conditions, the CFU numbers of P3UCO-S1 strain cultured in the presence of 2.5%, 5%, and 10% H2 were (1.0 ± 1.15) × 106/mL, (1.60 ± 0.16) × 107/mL, and (2.67 ± 0.5) × 108/mL, respectively. The CFU number of 2.5% H2 was significantly lower than the CFU numbers of 5% and 10% H2 (P \u003c 0.0001 and P \u003c 0.005, resp.). The CFU number of 5% H2 was significantly lower than the CFU number of 10% H2 (P \u003c 0.005) (Figure 1)."}
