In order to purify biogas slurry and biogas simultaneously, three different fungi, Pleurotus geesteranus (P. geesteranus), Ganoderma lucidum (G. lucidum), and Pleurotus ostreatus (P. ostreatus) were pelletized with Chlorella vulgaris (C. vulgaris). The results showed that the optimal light wavelength ratio for red:blue was 5:5 for these three different fungi-assisted C. vulgaris, resulting in higher specific growth rate as well as nutrient and CO removal efficiency compared with other ratios. G. lucidum/C. vulgaris was screened as the best fungi-mialgae for biogas slurry purification and biogas upgrading with light/dark ratio of 14h:10h, which was also confirmed by the economic efficiency analysis of the energy consumptions. These results will provide a theoretical foundation for large-scale biogas slurry purifying and biogas upgrading using microalgae.
为了同时净化沼气和沼气液，使用小球藻（Chlorella vulgaris）对三种不同的真菌，包括糙皮侧耳（Pleurotus geesteranus）、灵芝（Ganoderma lucidum）和糙皮侧耳（Pleurotus ostreatus）进行了球化处理。结果表明，对于这三种不同的真菌辅助小球藻，红光：蓝光的最佳光波长比为 5:5，与其他比例相比，具有更高的比生长速率以及营养物质和 CO 的去除效率。灵芝/小球藻（Ganoderma lucidum/C. vulgaris）被筛选为用于沼气液净化和沼气升级的最佳真菌-藻类，其在光/暗比为 14h:10h 时效果最佳，这也通过对能源消耗的经济效益分析得到了证实。这些结果将为使用微藻大规模净化沼气液和升级沼气提供理论基础。
