Hydrogen production from Saccharina Japonica by simultaneous dark fermentation (DF) and microbial electrolysis cell (MEC), called sDFMEC, was studied. In the novel sDFMEC process, substrates were converted to H and volatile fatty acids (VFAs) by DF in the bulk phase, and VFAs are simultaneously oxidized by the exoelectrogens in the microbial film on anode electrode with further production of H at the cathode. The sDFMEC process was compared with DF and a combined process of DF and MEC in series (DF-MEC) in terms of H production. The overall H production from S. Japonica in sDFMEC process was higher (438.7 ± 13.3 mL/g-TS), than DF (54.6 ± 0.8 mL/g-TS) and DF-MEC (403.5 ± 7.9 mL/g-TS) process, respectively, which is approximately 3-times higher than those reported in the literature.
研究了通过同步暗发酵（DF）和微生物电解池（MEC）（称为 sDFMEC）从紫菜中生产氢气。在新型 sDFMEC 工艺中，基质在主体相中通过 DF 转化为 H 和挥发性脂肪酸（VFAs），VFAs 同时被阳极微生物膜中的异化菌氧化，在阴极进一步产生 H。与 DF 和 DF 与 MEC 串联的组合工艺（DF-MEC）相比，sDFMEC 工艺在 H 生产方面具有优势。与 DF（54.6±0.8 mL/g-TS）和 DF-MEC（403.5±7.9 mL/g-TS）相比，sDFMEC 工艺中从紫菜中获得的总 H 产量更高（438.7±13.3 mL/g-TS），分别约为文献报道值的 3 倍。
