such as lactate, ethanol, acetone, butanol, or alanine. Taking into account that there is no real-time separation of hydrogen in our batch experiment, it is speculated that hydrogen accumulated in the headspace... separation of hydrogen. In addition, considerable amounts of heavy metals were also determined in MPBRs, such as Mg (4828 mg/kg, TS), and Ca (86745 mg/kg, TS). Studies have found that hydrogen production......
