| 中文摘要 |
| 通过筛选获得1株Shewanella baltica，分别改变阳极基质种类、浓度、pH和温度，考察不同条件下接种该菌后MFC产电特性.乳酸钠作为基质时接种该菌的MFC产电功率密度最大，MFC产电功率密度和基质浓度满足Monod模型.阳极溶液pH和温度对接种该菌的MFC产电功率密度影响最大.阳极溶液pH为8时接种该菌的MFC产电功率密度最大可达1 236 mW/m2，最大功率密度上升主要是阳极内阻和阳极电势影响所致.接种该菌的MFC最大产电功率密度在50℃达到1 197 mW/m2，最大功率密度随温度变化的主要原因是温度对阳极内阻的影响，20～50℃时MFC电流密度与温度满足Arrhenius方程. |
| 英文摘要 |
| The influences of the anodic substance，concentration，pH and temperature on the electricity production by MFCs were discussed.The lactic sodium was better than acetic sodium or glucose.The power density of MFC and the concentration of lactic sodium were well filled with Monod model.The power density was 1 236 mW/m2 when the pH of anodic chamber was 8.The power density of MFC increased with the pH increasing from 6 to 8，which was due to the anodic internal resistance.The power density was 1 197 mW/m2 when the temperature was 50℃.The power density of MFC changed with temperature because the anodic resistance decreased with the temperature increasing.While the temperature changed from 20℃ to 50℃，the current density and the temperature were well filled in Arrhenius equation. |
