| 摘 要： | ［目的］ 为了找到可以加速微藻富集的合适絮凝剂。［方法］ 制备了壳聚糖的降解产物壳寡糖，用于绿色巴夫藻（Pavlovaviridis Tseng, Chen et Zhang）和小球藻（Chloreiia spp.） 絮凝富集。［结果］ 终浓度为30 mg/L以上的壳寡糖溶液对2种藻类具有显著的促沉降效应。当壳寡糖与6 mg/L聚合氯化铝混合使用时，壳寡糖/聚合氯化铝促沉降效应明显提高。［结论］ 壳寡糖可以用于微藻大规模生产的采收。

| Abstract: | Objective ] The research aimed to find the optimum floeculant agent which could accelerate the gathering of microalgae. Meth- od ] The derivatives of chitosan, chitooligosacchafide were prepared, and its application in gathering of microalgae Pavlovaviridis Tseng, Chen et Zhang and Chloreiia spp. was investigated. Result] Chitooligosaccharide with concentration higher than 30 mg/L promoted the flocculation of the two species. Its complexes with 6 mg/L poly aluminium chloride were able to improve the＇ flocculation significantly. Conclusion] Chitooligosaccharide could be used in the large-scale collection of microalgae. |
