- Title:
- Vallisneria natans for Improvement of Oxidation Reduction Characteristics and Microbial Community Structure of Sediment
- Keywords:
- Vallisneria natans; black and odorous water; sediment; oxidation reduction potential (ORP); microbial community structure
- 摘要:
- 选取氧化还原电位（ORP）作为黑臭水体及底泥性状的重要评判指标，针对苦草（Vallisneria natans）修复水体及底泥的效果开展了研究，并对苦草根系区域底泥中的微生物进行了高通量测序分析。结合水体的COD、氮、磷及底泥的TOC、TN等指标的检测结果发现，苦草对水体及底泥中的ORP提升效果明显，其中水体的ORP提高了约24%，表层底泥的ORP提高了52%；苦草对底泥中的微生物群落结构改善明显，微生物群落结构丰富度增加，另外，有利于底泥中物质能量转换的微生物占比明显增加，如Bacillus、Steroidobacteraceae、Thiobacillus、Clostridium等。
- Abstract:
- This paper selected oxidation reduction potential (ORP) as an important evaluation index, investigated the effect of Vallisneria natans on the remediation of black and odorous water and sediment, and analyzed the microbial community of the sediment in the root area of Vallisneria natans by high-throughput sequencing. The detection results of COD, nitrogen, phosphorus in water and TOC and TN in sediment indicated that the ORP in the water and sediment was significantly improved, among which the ORP in the water was increased by approximately 24% and that in the surface sediment was increased by 52%. Vallisneria natans significantly improved the microbial community structure in the sediment, and increased the richness of microbial community. The relative abundance of microorganisms (such as Bacillus, Steroidobacteraceae, Thiobacillus and Clostridium) conducive to the material?energy conversion in the sediment increased significantly.
