Comparison of chitin-dependent hydrogen (H2) production in KU216 and KC04ΔtM1 in ASW-VMT-SC medium (A) and in ASW-VMT medium (B). Total hydrogen represents the amount of molecular hydrogen present in the headspace of a culture bottle per milliliter of culture volume (medium volume was 15 ml). Error bars represent standard deviations of three independent cultivations. The results show that strain KC04ΔtM1 exhibits hydrogen production dependent on swollen chitin.
