Time-course profiles of cell growth and H2 production by wild-type Y19 and Y19-PR1 grown on maltose as carbon source. a, b Represent wild-type C. amalonaticus Y19 while c and d represent Y19-PR1. Each strain was grown in the absence (a, c) and presence (b, d) of CO. Symbols cell growth (open circle), CO consumption (closed circle), H2 production (open square) and pH (cross)
