【摘要】 研究不同摄食状态罗非鱼养殖水体微生物群落功能多样性差异。利用Biolog技术对不同摄食状态下罗非鱼养殖水体微生物群落对六大类碳源利用情况及其微生物群落功能多样性与环境因子间的关系进行研究。结果显示:不同摄食状态罗非鱼养殖水体微生物对醇类和胺类的利用强度均存在显著性差异,对其它类碳源利用情况基本相同;RDA分析表明,NH4+-N、NO2--N、NO3--N是影响不同摄食状态罗非鱼养殖水体微生物群落功能多样性差异的主要因素。结果表明:不同摄食状态的罗非鱼养殖水体微生物群落功能多样性存在一定差异。更多还原

【Abstract】 The difference of functional diversity of aquatic microbial community in tilapia ponds under different food intake was examined in this paper. The Biolog technique was used to study the utilization of six carbon sources and the relationship between functional diversity of microbial communities and environmental factors in microbial communities of tilapia aquaculture in different feeding conditions. The results showed that both alcohols and amines utilized by microbes in the tilapia ponds under different food intake were significantly different, the utilization of other types of carbon sources is basically the same. RDA analysis revealed that NH4+-N, NO2--N, NO3--N were the critical environmental factors influencing the differences of functional diversity of aquatic microbial community in tilapia ponds under different food intake. The results indicate that there are some differences in functional diversity of aquatic microbial communities in tilapia ponds under different food intake.更多还原
