为筛选高效复合溶藻菌群，分析了NP23、P25、Am11、混合菌a（NP23∶P25∶Am11＝1∶1∶1）、混合菌 b（NP23∶P25∶Am11＝3∶1∶1）和混合菌 c（NP23∶P25∶Am11＝1∶1∶3）对小球藻、栅藻、惠氏微囊藻、蛋白核小球藻和铜绿微囊藻的溶藻效果。结果表明：对于以小球藻为主体的富营养化水体，混合菌比单菌 Am11的溶藻效果低6％～14．1％；以栅藻、蛋白核小球藻、惠氏微囊藻和铜绿微囊藻为主体的富营养化水体，混合菌 b 和混合菌 a 比单菌 NP23、P25和 Am11的溶藻效果高7．2％～34．7％；混合菌 b 和混合菌 a 的溶藻效果都高于单菌，且在投菌后6 d 内的溶藻率都能达到90％以上。结论：混合菌对混合藻有较好的溶藻效果，可为混合溶藻菌剂的实际应用提供参考。

The algae-lysing effect of NP23,P25,Am11,mixed bacteria a (NP23∶P25∶Am11=1∶1∶1),mixed bacteria b(NP23∶P25∶Am11 =3∶ 1 ∶ 1)and mixed bacteria c(NP23∶P25 ∶Am11 = 1 ∶1∶ 3 )on Chlorella,Scenedesmus, Microcystis wesenbergii , Microcystis aeruginosa and Chlorella pyrenoidosa was analyzed to select efficient composite algicidal bacteria.The results showed that:1)The algae-lysing effect of three mixed bacteria was lower than Am11 in the eutrophic water mainly occupied with Chlorella and the descend range was 6% ~14.1%;2)The algae-lysing effect of mixed bacteria a and mixed bacteria b was 7.2% ~ 34.7% higher than NP23,P25 and Am11 in the eutrophic water occupied with Scenedesmus,Microcystis wesenbergii ,Microcystis aeruginosa and Chlorella pyrenoidosa and the algae-lysing rate of mixed bacteria a and mixed bacteria b could be up to above 90% during six days.The mixed bacteria with better algae-lysing effect can be used in practical application.
