Paulownia biomass is rich in carbohydrates, making which a potential feedstock for biohydrogen production. In the study, different parts and varieties of Paulownia were chose as substrates to evaluate hydrogen production potential of paulownia lignocellulose via biohydrogen production by photo fermentation (BHPPF) and energy conversion efficiency (ECE). Results showed the highest cumulative hydrogen yield (CHY) of 67.11 mL/g total solids (TS) and ECE of 4.74% were obtained from leaves of Paulownia, which were 121.06% and 115.45% higher than those of the branches. Moreover, Paulownia jianshiensis leaves were found to be the best variety for BHPPF, with the maximum CHY of 98.83 mL/g TS and ECE of 7.18%. Using Paulownia waste as the substrate to produce hydrogen helps broaden the range of raw materials for BHPPF and improve the economic utilization of forestry waste.
泡桐生物质富含碳水化合物，是生物制氢的潜在原料。本研究以不同部位和品种的泡桐为底物，通过光发酵生物制氢（BHPPF）和能量转化效率（ECE）评估泡桐木质纤维素的产氢潜力。结果表明，泡桐叶的累计氢气产量（CHY）最高，达到 67.11 mL/g 总固体（TS），能量转化效率（ECE）为 4.74%，分别比树枝高出 121.06%和 115.45%。此外，发现泡桐剑叶是 BHPPF 的最佳品种，最大 CHY 为 98.83 mL/g TS，ECE 为 7.18%。利用泡桐废料作为生物制氢的底物有助于拓宽 BHPPF 的原料范围，提高林业废料的经济利用价值。
