High solid phase and easily congeal affect the mass transfer in the photo-fermentative biohydrogen production when taken straw biomass as substrate. Hence, oscillator was adopted to provide the shaking condition to enhance the mass transfer situation in this paper. Diverse shaking velocity (0, 80, 120 and 160 rpm) and substrate concentration (0, 2, 4, 6, 8 and 10 g) were studied, to evaluate the influence on the hydrogen yield capacity. The results showed that shaking could help to accelerate of gas release, shorten the fermentation time, and improve hydrogen production rate. Hydrogen yield was significantly enhanced at high substrate concentration under shaking condition. Highest hydrogen yield of 57.08 ± 0.83, 57.62 ± 1.37, 62.28 ± 0.84 mL/g-volatile solids (VS) were observed at shaking velocities of 80, 120 and 160 rpm with 6, 8 and 10 g corn stover powder, respectively. On the contrary, shaking significantly reduced the potential of hydrogen yield at a low substrate concentration, and the lower hydrogen yield obtained at the higher shaking velocity. As the lowest hydrogen yields of 27.68 ± 1.02 and 41.93 ± 0.40 mL/g VS were obtained at shaking velocity of 160 rpm with 2 and 4 g corn stover powder, respectively.

当以秸秆生物质为底物时，高固相和易凝结影响光发酵生物制氢过程中的传质。因此，本文采用振荡器来提供振动条件，以增强传质情况。研究了不同的摇动速度（0、80、120和160 rpm）和底物浓度（0、2、4、6、8和10 g），以评估其对制氢能力的影响。结果表明，摇动有助于加速气体释放，缩短发酵时间，提高产氢率。在较高的底物浓度下，在摇动条件下，氢气产率显着提高。在80、120和160 rpm的振摇速度下，6时的最高氢产率为57.08±0.83、57.62±1.37、62.28±0.84 mL / g挥发性固体（VS）分别为8克和10克玉米秸秆粉。相反，摇动显着降低了在低底物浓度下的氢产率的潜力，以及在较高的摇动速度下获得的氢产率较低。在160 rpm的摇动速度下，分别用2 g和4 g玉米秸秆粉获得的最低氢气产率为27.68±1.02和41.93±0.40 mL / gVS。
