摘要: 采用Biolog ECO微平板法检测了4口养殖前期投放或不投放芽孢杆菌制剂的罗非鱼池塘水体及底泥微生物群落代谢功能的变化情况,研究芽孢杆菌制剂对养殖前期罗非鱼池塘微生物群落代谢功能的影响。结果表明:芽孢杆菌制剂对底泥微生物群落的代谢活性、功能多样性及6大类碳源的利用有明显的促进作用,而对水体微生物群落代谢活性和功能多样性的影响不明显,但促进了水体微生物对6大类碳源的利用。研究结果证实,在养殖前期投放芽孢杆菌制剂有利于改善罗非鱼养殖池塘微生物群落的代谢功能,主要体现在提高底泥微生物群落的代谢功能上。

Abstract: In order to understand the effects of Bacillus preparation on the metabolic function of microbial communities in tilapia ponds at early stock stage, Biolog ECO microplate was used to examine the changes of the metabolic function of microbial communities in the waters and sediments from four tilapia ponds, of which, two trial ponds were applied with Bacillus preparation at early stock stage. For the microbial communities in sediments, Bacillus preparation had obvious promotion effects on the metabolic activity, functional diversity, and utilization of six kinds of carbon sources; while for those in waters, Bacillus preparation had little effects on their metabolic activity and functional diversity, but promoted their utilization of six kinds of carbon sources. Our study indicated that putting Bacillus preparation into tilapia ponds at early stock stage could improve the metabolic function of microbial communities in the ponds, especially in sediments.
