title: Influence of Different Electron Acceptors on the Anaerobic Degradation of Curly-Leaf Pondweed.
abstract: Curly-leaf pondweed (Potamogeton crispus) was utilized as the representative to investigate the biodecomposition process of aquatic plants under different reducible conditions. Results showed that the methane production was inhibited when different electron acceptors (Fe(III), <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="02257-ilm01.gif"/> and <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="02257-ilm09.gif"/>) were available. The methane production was decreased by 57% when Fe(III) and <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="02257-ilm10.gif"/> or <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="02257-ilm11.gif"/> were both available compared to the control. The degradation efficiency of hemicellulose and lignin with Fe(III) and <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="02257-ilm12.gif"/> were increased significantly. This provided a theoretical basis for slowing down the emissions of methane.
