The purification effect of two different microalgae-fungi-bacteria symbiosis technologies on biogas and biogas slurry was studied to determine the best symbiosis treatment technology and the suitable concentration of GR24. The results showed that the purification effect of biogas slurry in Chlorella vulgaris-Ganoderma lucidum-endophytic bacteria (S395-2) symbiont co-culture system was better than that of the biogas slurry in Scenedesmus obliquus-Pleurotus ostreatus-S395-2 symbionts. Following 10 M GR24 treatment, Chlorella vulgaris-Ganoderma lucidum-S395-2 symbionts had elevated mean daily production rate and growth rate by 1.92 and 1.46 folds in comparison with blank group. After adjusting the GR24 level within the range of 10 M-10 M, Ganoderma lucidum-assisted Chlorella vulgaris-S395-2 attained higher maximal removal rates for TN, COD, CO, and TP by 10.78%, 14.62%, 3.86%, and 9.07%, respectively, compared to the rates when GR24 was not added.
研究了两种不同的微藻-真菌-细菌共生技术对沼气和沼液的净化效果，以确定最佳的共生处理技术和 GR24 的适宜浓度。结果表明，小球藻-灵芝-内生菌（S395-2）共生共培养系统中沼液的净化效果优于斜生栅藻-平菇-S395-2 共生体中的沼液。经 10 M GR24 处理后，小球藻-灵芝-S395-2 共生体的平均日产量和增长率分别比空白组提高了 1.92 倍和 1.46 倍。在 10 M-10 M 范围内调整 GR24 水平后，灵芝辅助小球藻-S395-2 对 TN、COD、CO 和 TP 的最大去除率分别提高了 10.78%、14.62%、3.86%和 9.07%，而未添加 GR24 时的去除率。
