里下河地区湖群夏季表层沉积物微生物多样性分析
首发时间:2010-12-09
摘要:应用PCR-DGGE技术对江苏省里下河地区湖群夏季表层沉积物中微生物多样性进行调查研究和分析,结果显示:夏季表层沉积物中微生物多样性非常丰富,且其在各湖泊的分布存在明显的空间差异性,各湖泊形成了自己特定生态位的群落结构;通过应用Statistica 7软件对Shannon-Weiner指数和各理化指标进行相关性分析发现,里下河地区湖群的微生物群落多样性指标与各理化指标之间均不存在显著相关关系,微生物活动对总磷的影响较对其他物化指标的影响大。

Analysis of Microbial Diversity in Superficial Deposit of Lakes in Lixia River Area in Summer
Abstract:IPoly-merase chain reaction-denaturing gradient gel electrophoresis(PCE-DGGE) was applied to study and investigate the microbial diversity in superficial deposit of lakes in Lixia River area in summer. The results indicated that superficial deposit was rich in microbial diversity which differed obviously from lake to lake, and there existed community structure of their own particular ecological niche in each lake; By correlation analysis between Shannon-Weiner index and physicochemical indicators with Statistica software, little significant correlation at p<0.05 level was observed between the microbial community structure diversity index and each of those physicochemical indicators in the study area.And microbial activity impacts more on total phosphorus than the other physicochemical indicators.
Keywords: Microbial Diversity PCR-DGGE Superficial Deposit correlation analysis
