摘要: 旨在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,对其他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。

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