  摘要:为从情况微生物的角度评论辩论生物浮床的水质疗养机理,采取宏基因组学测序技巧和生物信息学手腕,剖析了情况微生物和根系微

  生物 群落的多样性 .研究 结果标明 , 鱼菜 共生形式下 优势菌门是变形 菌门 (Proteobacteria) 、蓝细 菌门(Cyanobacteria) 、拟 杆菌门

  (Bacteroidetes) 、放线菌门(Actinobacteria) 、绿弯菌门(Chloroflexi)和厚壁菌门(Firmicutes)等,主要菌属是聚球藻属(Synechococcus) 、

  hgcI_clade 、CL500 -29_marine_group 、芽孢杆菌属(Bacillus)和分支杆菌属(Mycobacterium)等;空心菜根系微生物群落中最丰富的优势

  菌门是变形菌门和蓝细菌门,主要菌属是红细菌属(Rhodobacter) 、噬氢菌属(Hydrogenophaga)和聚球藻属等.研究结果还标明低掩饰率

  (3.5%) 的空心菜生物浮床可以添加水体的消融氧含量, 降低水体中含氮化合物的浓度和改良养殖情况中的微生态平衡,提高有益菌和氮

  Abstract :In order to investigate the influence on water quality and microbial diversity in intensive fish pond by Ipomoea

  aquatica floating-bed, and the composition and diversity of microbial communities in the samples were researched based

  on high throughput sequencing of 16S rRNA gene. The results revealed that the dominant bacteria were phyla

  Proteobacteria, Cyanobacteria, Bacteroidetes, Actinobacteria, Chloroflexi and Firmicutes, the dominant bacteria were

  genera Synechococcus, hgcI_clade, CL500 -29_marine_group, Bacillus and Mycobacterium in the Aquaponics System,

  and the most dominant bacteria of rhizosphere microorganisms were phyla Proteobacteria and Cyanobacteria, the

  dominant bacteria were genera Rhodobacter, Hydrogenophag
