摘　　要：利用超滤技术浓缩单胞藻 ,易于冷冻干燥及保存 ,提高劳动生产率 ,增加产量满足工业化要求。本实验选用板框式超滤器方法进行单胞藻浓缩实验 ,主要包括超滤膜规格的筛选 ,浓缩实验 ,滤膜的清洗等 ,结果表明经超滤处理后单胞藻浓度可达每毫升24×108个 ,冷藏存放3个月后 ,对脂肪酸组分及含量进行分析 ,并再接种培养和成活率检测 ,结果良好。Ultra-filtration methods used in the current study indicated the method could yield 6 million cells per milliliter after condensing treatment on the Chlorella solution. Preserved for three months, the growth curves were similar to those before the condensation. There is no obvious difference in component and content of fatty acids in samples both before and after treatment. This experiment showed that the methods can be applied for large scale of the chlorella solution.
