When the H\n                    <jats:sub>2<\/jats:sub>\n                    production reached a plateau, the headspace of the reactors were flushed with N\n                    <jats:sub>2<\/jats:sub>\n                    and reactors were re-incubated. Afterwards, only the reactors with phosphate buffer showed a second cycle of H\n                    <jats:sub>2<\/jats:sub>\n                    production and 48% more H\n                    <jats:sub>2<\/jats:sub>\n                    was obtained. The absence of a second cycle in non-buffered reactors could be related to a lower final pH than in the buffered reactors; the low pH could drive the fermentation to solvents production. Indeed a high solvent production was observed in non-buffered bioreactors as given by low \u03c1 ratios (defined as the ratio between sum of organic acid production and sum of solvents production). Regarding the process temperatures, no significant difference between the H\n                    <jats:sub>2<\/jats:sub>\n                    production of reactors incubated at ambient temperature and at 35\u00b0C was described.
