| 摘 要： | 通过限制性培养技术富集大庆湿地水样中的可培养蓝藻,采用显微镜观察法对可培养蓝藻进行观察及鉴定。结果表明,大庆湿地可培养蓝藻含单细胞蓝藻和丝状蓝藻,在不同类型湿地中不同时期的水样中可培养蓝藻的类群是不同的。经显微镜观察初步鉴定,大庆湿地水体中可培养蓝藻菌株主要分布在4个目,即色球藻目(Chroococcales)、胶须藻目(Rivulariales)、颤藻目(Oscillatoriales)和念珠藻目(Nostocales),8个属,即聚球藻属(Synechococcus)、集胞藻属(Synechocystis)、眉藻属(Calothrix),鞘丝藻属(Lyngbya)、束藻属(Symploca)、微鞘藻属(Microcoleus)、席藻属(Phormidium)和鱼腥藻属(Anabaena)和1个类群,即蓝绿藻类群(Gloeocapsa group)。

Distribution and Identification of Cultivable Cyanobacteria from Water Sample in Daqing Wetland |
| |
| Abstract: | Cultivable Cyanobacteria was enriched by limited-culture technology,the cultivable cyanobacteria in Daqing wetland was observed and identified by microscope. The results showed that there were unicellular and filamentous cultivable cyanobacteria in Daqing wetland,cultivable cyanobacterial species were different in different type wetlands at different sample stages. By the identification of microscopic observation,the observed cyanobacteria were distributed into 4 orders of chroococcales,Rivulariales, Oscillatoriales and Nostocales,8 genus of Synechococcus,Synechocystis,Calothrix,Lyngbya,Symploca,Microcoleus,Phormidium, Anabaena and Gloeocapsa group. |
