中文摘要：

以铜绿微囊藻（Microcystis aeruginosa）FACHB905为研究对象，对4种条件下：（1）25℃＋400μmol／mol（对照组）；（2）29℃＋400μmol／mol（温度升高组）；（3）25℃＋800μmol／mol（CO2升高组）；（4）29℃＋800μmol／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CO2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（Maeruginosa）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（P〈0．05），但单个藻细胞的平均产毒量不会随CO。浓度升高而提高。上述结果说明全球气候变化（大气温度与CO2浓度的同时升高）将有可能造成铜绿微囊藻（Maeruginosa）水华的生物量增加，总产毒量将随之增加。

英文摘要：

Abstract： The study focused on Microcystis aeruginosa FACHBg05 which was grown under the conditions of 25 ℃＋400 μmol/mol for control group, 29 ℃＋400 μmol/mol for elevated temp. group, 25 ℃＋800 μmol/mol for CO2 elevated group and 29 ℃ ＋800 μmol/mol for green house effect group. After the incubation, biomass of each culture and total content of microcystin were measured. Findings of the study suggested that the elevation of both temperature and CO2 could synergetically stimulate growth of M. aeruginosa, while increase of CO2 concentration could boost the production of total content of microcystin; in addition, there existed a significant positive correlation （P〈0.05） between total toxin content and algae biomass, however, the average microcystin content in a single cell won＇t increase with the elevation of CO2 concentration. Thus, results of the study implied the green-house effect would boost the biomass growth of M. aeruginosa in the case of algal bloom, and total amount of microcystin would increase correspondingly.
