Surface water was sampled at the three red tide stations during the Guinardia delicatula bloom in Jiaozhou Bay on February 9-10, 2004 and the colloidal substances were separated by filtration(0.7μm)and cross-flow ultrafiltration (1000 Daltons). The organic carbon in the filtrates and retentates were analyzed respectively. Heterosigma akashiwo and Skeletonema costatum were cultured in the 000Daltons ultrafiltrate and the retentates with different amount of colloidal substances (1000 Daltons-0.7μm).

2004年2月9~10日在胶州湾发生的柔弱几内亚藻赤潮期间分别在3个典型赤潮站位采集表层水样，利用过滤(0.7μm)和切向超滤(1000 Daltons)分离赤潮暴发水体中的胶体物质，分析了不同滤液及截留液的有机碳含量，并将赤潮异弯藻和中肋骨条藻在000 Daltons的超滤液及具有不同含量胶体物质(1000Daltons~0.7μm)的截留液中进行培养。
