Hydrogen production from dark fermentation has potential application due to its environmental friendliness, low production cost, and sustainability. However, there is still an obstacle to improving the efficiency of bioH production to meet the requirements in practical applications. In this research, copper molybdates are synthesized under different pH conditions as additives to study their different influence processes during anaerobic hydrogen production from cotton straws with the pure cultural system. A series of results indicate that CuMoO with appropriate experimental conditions has the highest H yield at 191.3 mL/g straws at 37 °C, which is 236% higher than the control group. It can be shown that O. ethanolica 8KG-4 has an obvious accompanying with high stability and low cytotoxicity for this clean energy production system as well as the improvement of metabolic pathway. These results extend new thinking of obtaining higher H yield as a biofuel in future production.
氢气的暗发酵生产具有环境友好、生产成本低和可持续性等优点，因此具有潜在的应用前景。然而，仍然存在一个障碍，需要提高生物 H 的生产效率，以满足实际应用的要求。在这项研究中，铜钼酸盐在不同的 pH 条件下合成，作为添加剂来研究它们在纯培养系统中厌氧发酵棉花秸秆生产氢气过程中的不同影响。一系列结果表明，在 37°C 下，具有适当实验条件的 CuMoO 的产氢量最高，为 191.3 mL/g 秸秆，比对照组高 236%。可以表明，O. ethanolica 8KG-4 具有明显的伴随作用，并且对这种清洁能源生产系统以及代谢途径的改善具有高稳定性和低细胞毒性。这些结果为未来生产中获得更高的生物燃料 H 产量提供了新的思路。
