摘要

摘要: 以厦门湾海水中的底泥为接种物筛选得到1株具有电化学活性的菌株XMS-1，研究该菌株相关特性及其在环境污染控制中的应用。根据菌株的形态、生理生化性质及16S rRNA基因测序的结果确定其种属，并用以构建微生物燃料电池，研究该菌株的产电性能，以及对典型重金属污染物Cr （Ⅵ）的还原能力。菌株XMS-1经鉴定属于Shewanella属，当MFC中接种初始浓度OD₆₀₀为0.3时可获得最大功率密度18 mW/m²、电流密度243 mA/m²，细菌能够在pH为7~8和NaCl含量为0~6%条件下实现对Cr （Ⅵ）的还原。XMS-1该菌株能在较宽的pH和较高的盐度条件下高效还原Cr（Ⅵ），并且具备良好的电化学活性，为微生物直接处理含盐工业废水和实现海水资源化利用提供了新的研究思路和数据参考。

Abstract: An electricity-producing strain XMS-1 was screened from sediments in the Xiamen Bay, and its related characteristics and application in environmental pollution control were analyzed. According to the morphological, biochemical properties of the strain and the results of 16S rRNA gene sequencing, the species and genera of the strain were determined. The electricity production performance of the strain was studied by constructing microbial fuel cell. At the same time, the reduction ability of hexavalent chromium, a typical heavy metal pollutant, was also explored. The bacterium was identify as Shewanella. When the initial inoculation concentration in MFC was OD₆₀₀=0.3, the maximum power density was 18 mW/m² and the current density was 243 mA/m². The bacterium could reduce Cr(Ⅵ) at pH of 7~8, and NaCl concentration of 0~6%. And this bacterium was proved to be capable of reducing Cr(Ⅵ) under the condition of wide pH and high salinity, and had good electricity production capacity. The bacterium XMS-1 had good potential in practical industrial wastewater treatment and provided scientific basis for seawater reclamation.
