This study aims to investigate the efficacy of lipid induction in Scenedesmus abundans by adding the effluent from dark fermentation of biohydrogen production. Four sets of experiments were conducted: control (sufficient nitrogen), nitrogen depletion, low concentration (0.3×) effluent addition, and high concentration (0.5×) effluent addition. The addition of low concentration effluent produced the highest biomass and lipid yields of 2.831 g/L and 1.238 g/L, corresponding to a lipid abundance of 43.72 wt%. Furthermore, S. abundans had high removal efficiencies for volatile fatty acids in the effluent (formic acid 100%, acetic acid 100%, propionic acid 98%, lactic acid 84%, and butyric acid 68%), and this is the first study demonstrating the ability of S. abundans in using formic acid and lactic acid to produce biomass and lipids. These results show that S. abundans have great abilities in simultaneous reducing organic acids in the effluent and producing valuable metabolites.

这项研究旨在通过添加暗发酵产生的生物氢产生的废水来研究丰产海藻中脂质诱导的功效。进行了四组实验：对照（充足的氮），氮耗，低浓度（0.3倍）废水添加和高浓度（0.5倍）废水添加。添加低浓度的废水产生了最高的生物量和脂质产量，分别为2.831 g / L和1.238 g / L，对应于43.72 wt％的脂质丰度。此外，沙门氏菌对废水中的挥发性脂肪酸（甲酸100％，乙酸100％，丙酸98％，乳酸84％和丁酸68％）具有较高的去除效率，这是第一个研究证明了S. abundans的能力用甲酸和乳酸生产生物质和脂质。这些结果表明，沙门氏菌具有同时还原废水中的有机酸并产生有价值的代谢物的强大能力。
