Five strains algae (Golenkinia sp. SDEC-16, Chlorella vulgaris, Selenastrum capricornutum, Scenedesmus SDEC-8 and Scenedesmus SDEC-13) were screened as an effective way to promote recover electricity from MFC for kitchen waste anaerobically digested effluent (KWADE) treatment. The highest OCV, power density, biomass concentration and total lipid content were obtained with Golenkinia sp. SDEC-16 as the co-inoculum, which were 170mV, 6255mWm(-3), 325mgL(-1) and 38%, respectively. Characteristics of the organics in KWADE were analyzed, and the result showed that the hydrophilic and acidic fractions were more readily degraded, compared to the neutral fractions during the operation. Maximum COD and TN removal efficiency were 43.59% and 37.39% when inoculated with Golenkinia sp. SDEC-16, which were roughly 3.22 and 3.04 times higher than that of S. capricornutum. This study demonstrated that Golenkinia sp. SDEC-16 was a promising species for bioelectricity generation, lipid production and KWADE treatment.
五种藻类（金藻属 SDEC-16、普通小球藻、脆杆藻、SDEC-8 栅藻和 SDEC-13 栅藻）被筛选为促进从厨房废物厌氧消化液（KWADE）处理中回收电能的有效方法。当使用金藻属 SDEC-16 作为共接种物时，OCV、功率密度、生物质浓度和总脂质含量最高，分别为 170mV、6255mWm(-3)、325mgL(-1)和 38%。分析了 KWADE 中有机物的特性，结果表明，与中性部分相比，亲水性和酸性部分在运行过程中更容易降解。当接种金藻属 SDEC-16 时，最大 COD 和 TN 去除效率分别为 43.59%和 37.39%，分别比脆杆藻高 3.22 倍和 3.04 倍。本研究表明，金藻属 SDEC-16 是一种很有前途的生物电能产生、产脂和 KWADE 处理的物种。
