摘要: 对施用芽孢杆菌制剂后虾池底泥细菌群落的变化进行了研究。结果表明,芽孢杆菌制剂改变了虾池底泥细菌类群组成,增加了底泥好氧细菌的数量。利用ShannonWiener指数进行生物多样性分析,发现试验池和对照池底泥细菌的多样性指数(H)、丰度(D)和均匀度(J)在整个养殖过程的动态变化相似,前期较低,中期、后期和末期都有不同程度的升高。但是,与对照池相比,试验池的优势菌属发生了变化,黄杆菌属(Flavobacterium)和粘纤维菌属(Cytophaga)数量增加,而弧菌(Vibrio)和发光细菌(Photobacterium)数量相对减少,且对虾的成活率、体重和产量提高。

Abstract: Variation of bacterial communities in the sediment was studied after being treated by preparation of Bacillus.The results showed that the probiotic Bacillus changed bacterial species composition of sediment and increased the number of aerobic bacteria.Shannon-Wiener index was used to analyze the species diversity,it found that diversity index(H),abundance(D) and evenness(J) of three ponds were lower at prophase,all rose at metaphase、anaphase and telophase.However,compared with control pood,bacteria dominanted in experiment ponds changed,the number of Flavobacterium and Cytophaga increased,while the number of Vibrio and Photobacterium reduced relatively,and prawn survival rate,mean weight at harvest and production were improved.
