The growth, pH, substrate and metabolite concentrations and hydrogen production from the aerobic–anaerobic phases of the ADP1-g—C. butyricum cocultivations in 300 ml JM medium. Initial aerobic conditions turned to anaerobic via ADP1-g deoxygenation within 12 h of cultivation initiating glucose consumption and hydrogen production by C. butyricum. a OD600nm (open circle) and pH (closed square) trends of one-pot batch ADP1-g—C. butyricum cocultivations. b Glucose utilization (C. butyricum, open square), acetate–butyrate metabolism (acetate, open star; butyrate, open triangle) and hydrogen productivity mmol/l/h per culture volume (in bars) from cocultivation experiment. The data points are averaged from triplicate experimental repeats. In some cases, the symbols overlap and the error bars (standard deviation) are smaller than the symbol
