| 摘 要： | 以铜绿微囊藻（Microcystis aeruginosa)为供试藻类，从发生黄化的铜绿微囊藻液中分离出1株溶藻细菌，命名为H1，对溶藻细菌H1进行生理鉴定和16S rDNA序列分析，结果表明：该菌株为短芽孢杆菌属,H1菌对于铜绿微囊藻的降解特性表明该株溶藻细菌对于铜绿微囊藻有很好的去除效果，1 d后叶绿素a(chlorophyll a, chl a)去除率达到71.60%，7 d后chl a去除率为80.48%，在溶藻过程中，营养物质氮和磷从藻细胞内转移到了藻细胞外。 |

| Abstract： | One strain of algicidal bacteria named H1 was isolated from the etiolated Microcystis aeruginosa. Its physiological biochemistry characteristic and the results of 16S rDNA sequence analysis strongly suggested that algicidal bacteria H1 belonged to Brevibacillus sp. Its algicidal characteristic on Microcystis aeruginosa was tested. Results showed that the algicidal bacteria H1 had a good removal effect on Microcystis aeruginosa. The removal rates to chl-a reached 71.60% after 1 d and 80.48% after 7 d. During algicidal process, the phenomenon that nitrogen and phosphor were transferred from inside to outside of algae cell was also noticed. |
