背景：利用小球藻来实现生物燃料生产和废水营养物去除的双重目标非常有吸引力。而且，该技术与烟气（富含CO2）净化相结合被认为是提高生物燃料产量的有效途径。然而，废水的灭菌是一个消耗能源的步骤。 This study aimed to comprehensively evaluate a cost-effective method of culturingChlorella pyrenoidosain unsterilized piggery wastewater for biofuel production by sparging air or simulated flue gas, including algal biomass production, lipid production, nutrient removal rate and the mutual effects between algae and other microbes.Results:The average biomass productivity ofC. pyrenoidosareached 0.11 g L-1day-1/0.15 g L-1day-1and the average lipid productivity reached 19.3 mg L-1day-1/30.0 mg L-1day-1when sparging air or simulated flue gas, respectively. This method achieved fairish nutrient removal efficiency with respect to chemical oxygen demand (43.9%/55.1% when sparging air and simulated flue gas, respectively), ammonia (98.7%/100% when sparging air and simulated flue gas, respectively), total nitrogen (38.6%/51.9% when sparging air or simulated flue gas, respectively) and total phosphorus (42.8%/60.5% when sparging air or simulated分别为烟气）。培养 C．蛋白核对养猪废水中的微生物群落有很大影响。特别是培养C. pyrenoidosaenriched the abundance of the obligate parasite Vampirovibrionales, which can result in the death ofChlorella.Conclusion:The study provided a comprehensive evaluation of culturingC.用于生物燃料生产的未灭菌养猪废水。结果表明，这种成本有效的方法是可行的，但还有很大的改进空间。更重要的是，这项研究阐明了藻类和其他微生物之间的相互作用。特别是，发现了专性寄生虫吸血弧菌目对藻类生物量和脂质生产的有害影响。
Background:The utilization ofChlorellafor the dual goals of biofuel production and wastewater nutrient removal is highly attractive. Moreover, this technology combined with flue gas (rich in CO2) cleaning is considered to be an effective way of improving biofuel production. However, the sterilization of wastewater is an energy-consuming step. This study aimed to comprehensively evaluate a cost-effective method of culturingChlorella pyrenoidosain unsterilized piggery wastewater for biofuel production by sparging air or simulated flue gas, including algal biomass production, lipid production, nutrient removal rate and the mutual effects between algae and other microbes.Results:The average biomass productivity ofC. pyrenoidosareached 0.11 g L-1day-1/0.15 g L-1day-1and the average lipid productivity reached 19.3 mg L-1day-1/30.0 mg L-1day-1when sparging air or simulated flue gas, respectively. This method achieved fairish nutrient removal efficiency with respect to chemical oxygen demand (43.9%/55.1% when sparging air and simulated flue gas, respectively), ammonia (98.7%/100% when sparging air and simulated flue gas, respectively), total nitrogen (38.6%/51.9% when sparging air or simulated flue gas, respectively) and total phosphorus (42.8%/60.5% when sparging air or simulated flue gas, respectively). CulturingC. pyrenoidosastrongly influenced the microbial community in piggery wastewater. In particular, culturingC. pyrenoidosaenriched the abundance of the obligate parasite Vampirovibrionales, which can result in the death ofChlorella.Conclusion:The study provided a comprehensive evaluation of culturingC. pyrenoidosain unsterilized piggery wastewater for biofuel production. The results indicated that this cost-effective method is feasible but has considerable room for improving. More importantly, this study elucidated the mutual effects between algae and other microbes. In particular, a detrimental effect of the obligate parasite Vampirovibrionales on algal biomass and lipid production was found.
