摘　　要：为探究电解氧化技术处理海水对球等鞭金藻(Isochrysis galbana)8701、青岛大扁藻(Platymonas helgolandica var.tsingtaoensis)和牟氏角毛藻(Chaetoceros muelleri)生长繁殖的影响,实验设置电解氧化沙滤海水EOW_(250)(有效氯浓度为250 mg·L^(-1))、电解氧化沙滤海水EOW_(100)(有效氯浓度为100 mg·L^(-1))、漂白粉消毒沙滤海水(有效氯浓度为35 mg·L^(-1))3个实验组,以煮沸沙滤海水作为对照组,对球等鞭金藻8701、青岛大扁藻和牟氏角毛藻进行单种培养,培养时间10 d。结果显示,电解氧化技术处理海水适用于3种海洋微藻的培养,电解氧化海水EOW_(100)(有效氯浓度为100 mg·L^(-1))处理组球等鞭金藻8701在培养第10天获得最高细胞密度,为437.7×10^(4)cell·mL^(-1),且显著高于对照组(P<0.05);各处理组间青岛大扁藻的藻细胞终密度均无显著差异(P>0.05),电解氧化海水EOW_(250)(有效氯浓度为250 mg·L^(-1))、电解氧化海水EOW_(100)(有效氯浓度为100 mg·L^(-1))的最终细菌总数与漂白粉组之间存在显著性差异(P<0.05);牟氏角毛藻各组最终细菌总数没有显著差异(P>0.05)。综上所述,电解氧化海水EOW_(250)(有效氯浓度为250 mg·L^(-1))可用于培养青岛大扁藻,而电解氧化海水EOW_(100)(有效氯浓度为100 mg·L^(-1))适合培养球等鞭金藻8701、青岛大扁藻和牟氏角毛藻,研究旨在探究电解氧化法处理沙滤海水对微藻培养的影响,为饵料微藻规模化生产应用提供理论依据。To investigate the effect of electrolytic oxidation technology for treating seawater on the growth and reproduction of Isochrysis galbana 8701,Platymonas helgolandica var.tsingtaoensis and Chaetoceros muelleri,three experimental groups were set up,including electrolytic oxidation sand filtration seawater EOW_(250)(effective chlorine concentration of 250 mg·L^(-1)),electrolytic oxidation sand filtration seawater EOW_(100)(effective chlorine concentration of 100 mg·L^(-1)),and bleaching powder disinfection sand filtration seawater(effective chlorine concentration of 35 mg·L^(-1)),with boiled sand filtration seawater as the control group.Single species cultivation was carried out on Isochrysis galbana 8701,Platymonas helgolandica var.tsingtaoensis and Chaetoceros muelleri for 10 days.The results showed that electrolytic oxidation technology for treating seawater was suitable for the cultivation of three types of marine microalgae.The group treated with electrolytic oxidation seawater EOW_(100)(effective chlorine concentration of 100 mg·L^(-1))for Isochrysis galbana 8701 achieved the highest cell density of 437.7×10^(4)cell·mL^(-1)on the 10th day of cultivation,and significantly higher than the control group(P<0.05).There was no significant difference in the final cell density of Platymonas helgolandica var.tsingtaoensis among the treatment groups(P>0.05).However,there was a significant difference(P<0.05)in the final bacterial number between the electrolytic oxidation seawater EOW_(250)(effective chlorine concentration of 250 mg·L^(-1)),electrolytic oxidation seawater EOW_(100)(effective chlorine concentration of 100 mg·L^(-1))groups and the bleaching powder group.There was no significant difference in the the final bacterial number of Chaetoceros muelleri among the treatment groups(P>0.05).In conclusion,electrolytic oxidation seawater EOW_(250)(effective chlorine concentration of 250 mg·L^(-1))could be used for the culture of Platymonas helgolandica var.tsingtaoensis,while electrolytic oxidation seawater EO
