Comparison of the H2 production from the present contribution with the corresponding ones from the literature.

This comparison is not absolutely correct, because the conditions and the parameters used in the literature are totally different.*a): The maximal H2 production from Figure 5C.*b): The maximal H2 production from Fig. 8B.*c): The hydrogen production used for the comparison referred to the 5th incubation day.*d): The rate was calculated from the 1st to the 2nd incubation day.*e): The first number represents the comparison of the H2 production from the present contribution (Figure 5C) [4.7 mL H2 (mL PCV)−1] with the corresponding ones of other publications. The second number represents the comparison of our maximal H2 production (Figure 8B) [12.3 mL H2 (mL PCV)−1] with the corresponding ones of other publications.
