Tofu whey wastewater (TWW) is an abundant, nutrient riched and safety wastewater and is regarded as an excellent alternative medium in fermentation. In this study, the feasibility of algal cultivation using TWW as the basal medium was investigated. Results indicated that through simple pH adjustment, TWW presented a better culture performance at autotrophic, heterotrophic, and mixotrophic modes compared with that of regular green algae medium, BG-11. The biomass productivities of at each trophic mode were 4.76, 1.97, and 2.08 times higher than that cultured in BG-11 medium, respectively. Although a comparative or even lower lipid and protein content was obtained, much higher lipid and protein productivities were obtained in TWW compared to that of BG-11. The algal biomass accumulated in TWW can be used to produce high-value products. Therefore, TWW is a better alternative medium for efficient algal culture.

豆腐乳清废水是一种有前景的微藻培养基础培养基


豆腐乳清废水（TWW）是一种资源丰富、营养丰富且安全的废水，被认为是发酵中优良的替代培养基。本研究探讨了以TWW作为基础培养基培养藻类的可行性。结果表明，通过简单的pH调节，与常规绿藻培养基BG-11相比，TWW在自养、异养和混合营养模式下表现出更好的培养性能。各营养模式下的生物量生产力分别是BG-11培养基的4.76、1.97和2.08倍。尽管获得了相当的甚至更低的脂质和蛋白质含量，但与 BG-11 相比，TWW 获得了更高的脂质和蛋白质生产率。 TWW积累的藻类生物质可用于生产高价值产品。因此，TWW是高效藻类培养的更好替代培养基。
