3、00tLmol/mol(CO2升高组);(4)29℃+800v,mol/mol(温室效应组),藻的生物量及微囊藻毒素含量的变化进行了测定,结果表明:温度升高与CO:浓度升高能够协同刺激铜绿微囊藻(M.aeruginosa)的生长,CO浓度升高能导致铜绿微囊藻(aeruginosa)培养物中总毒素含量的上升,且总毒素含量与藻的生物量显著正相关(P4、增加,总产毒量将随之增加。关键词:温室效应;铜绿微囊藻;微囊藻毒素中图分类号:X172文献标志码:Adoi:10.39690.issn.1003—6504.2014.09.001文章编号:1003—6504(2014)09—0001-04EffectsofElevatedCO2andTemperatureonGrowthandMicrocystinProductiOilofMicrocystisaeruginosaGAOin,XUMin,XUEXueyang,ZHAOYijun一,ZHAOJin.CHENGKai,(1.5、SchoolofLifeScience,CentralChinaNormalUniversity,Wuhan430079,China;2.HubeiProvincialCooperativeInnovationCenter&SchoolofResourceandEnvironmentalEngineering。HubeiUniversityofTechnology,Wuhan430068,China)Abstract:ThestudyfocusedonMicrocystisaeruginosaFACHB905whichw6、asgrownundertheconditionsof25oC+40OpLmol/molforcontrolgroup,29oC+400wmol/molforelevatedtemp.group,25~C+800v~moYmolforCO2elevatedgroupand29℃+800~mol/molforgreenhouseeffectgroup.Aftertheincubation。biomassofeachcultureandtotalcontentofmicrocystinweremeasured.Finding7、softhestudysuggestedthattheelevationofbothtemperatureandCO2couldsynergeticallystimulategrowthofaeruginosa,whileincreaseofCO2concentrationcouldboosttheproductionoftotalcontentofmicrocystin;inaddition,thereexistedasignificantpositivecorrelation(P<0.05)betweentotalt8、oxincontentandalgaebiomass,however,theaveragemicrocystincontentinasinglecellwon’tincreasewiththeelevationofCO2concentrationThus。resultsofthestudyimpliedthegree
