摘　　要：小球藻作为水体中的初级生产者,是水生生态系统不可或缺的一部分,对促进物质循环、能量流动有着重要意义,同时也是水环境毒理学评价的标准试验藻种。为了给小球藻的水生态风险评估及相应产品的开发提供参考数据,本文系统分析了小球藻培养影响因素,概括了其产生的毒理效应,并对其营养价值与应用前景等进行了综述。本文认为温度、光照、pH、营养盐、氮磷比是小球藻规模化培养过程中的影响因素,重金属、农药、新型纳米材料、抗生素等污染物可对小球藻产生毒性效应,小球藻在污水处理、生物能源等领域具有较好的应用前景。Chlorella,a primary producer in the water body,is an indispensable part of the aquatic ecosystem.It is of great significance for chlorella to promote material circulation and energy flow.Chlorella is also a standard test algae species for toxicological evaluation of aquatic environment.In order to provide a basis for assessing the aquatic ecological risk of chlorella and developing its relative industrial chain,this paper analyzed the influencing factors during the process of chlorella culture,summarized the toxicological effects of pollutants on chlorella,and discussed its nutritional value and application prospect.Results show that the temperature,light,pH,nutrients,nitrogen/phosphorus ratio are the influencing factors in the process of large-scale cultivation of chlorella.The heavy metals,pesticides,new type of nano materials,antibiotics and etc.could cause significant toxic effects on chlorella.Chlorella has a good application prospect in the process of sewage treatment,bioenergy utilization and other fields.
