Chlorella pyrenoidosa was cultivated in soybean processing wastewater (SPW) in batch and fed-batch cultures without a supply of additional nutrients. The alga was able to remove 77.8 ± 5.7%, 88.8 ± 1.0%, 89.1 ± 0.6% and 70.3 ± 11.4% of soluble chemical oxygen demand (SCOD(Cr)), total nitrogen (TN), NH(4)(+)-N and total phosphate (TP), respectively, after 120 h in fed-batch culture. C. pyrenoidosa attained an average biomass productivity of 0.64 g L(-1)d(-1), an average lipid content of 37.00 ± 9.34%, and a high lipid productivity of 0.40 g L(-1)d(-1). Therefore, cultivation of C. pyrenoidosa in SPW could yield cleaner water and useful biomass.
蛋白核小球藻在分批和补料分批培养中利用大豆加工废水（SPW）进行培养，且无需额外提供营养物质。在补料分批培养 120 h 后，小球藻对可溶性化学需氧量（SCOD(Cr)）、总氮（TN）、NH(4)(+)-N 和总磷酸盐（TP）的去除率分别为 77.8 ± 5.7%、88.8 ± 1.0%、89.1 ± 0.6%和 70.3 ± 11.4%。小球藻的平均生物量生产力为 0.64 g L(-1)d(-1)，平均脂质含量为 37.00 ± 9.34%，脂质生产力为 0.40 g L(-1)d(-1)。因此，利用 SPW 培养蛋白核小球藻可以获得更清洁的水和有用的生物质。
