中文摘要：
以湿地植物仙羽蔓绿绒构建植物沉积型微生物燃料电池（Plant-SMFC）,分别考察阳极不同驯化方式及电极材料对电池基础特性的影响.结果表明：Plant-SMFC以阳极协同驯化方式富集产电菌时,电池启动期较自然驯化方式缩短了3d,产电水平亦明显提高,最大输出功率密度（2.84 mW/m2）为自然驯化方式的3.2倍,且该驯化方式对植物生长影响不大;活性炭纤维毡作为阳极电极材料效果优于石墨毡,电池启动期缩短了8d,最大输出功率密度（5.78 mW/m2）提高了1倍,同时更利于植物的生长繁殖,运行60 d后收获植物干质量为2.5g;高效液相色谱（HPLC）分析证明仙羽蔓绿绒根系分泌物中有机酸主要为顺丁烯二酸、反丁烯二酸、柠檬酸等小分子有机酸,它们均易被阳极产电菌利用以维持电池的稳定产电.
英文摘要：
As a kind of marshy plant, Philodendron cv. Xanadu was applied to construct a plant-sediment microbial fuel cell（Plant-SMFC）. The time of startup reduced by 3 d when using synergetic acclimation instead of natural acclimation for anodic electricigens, and the highest power density （2. 84 mW/m2 ） was 3.2 times than that of the latter. Results proved that there was no obvious harm on the growth of plant. The activated carbon fiber felt as anode material was better than the graphite one for the shorter startup time that was reduced by 8 d than the latter and higher power density of 5.78 mW/m2, 1 time higher than the latter, and further more, the former material was more helpful for the growth of plant with the dry weight of 2.5 g after 60 d. The constituents of organic acids in the root exudates were mainly maleic acid, fumaric acid and citric acid to be analyzed by high performance liquid chromatography （HPLC）. They were all low-molecular-weight organic acid that easy oxidated by anodic electricigens to generate e- lectron.
