      abstract     = {The worldwide energy demand constantly increases and the
                      search for regenerative alternatives is inevitable. A
                      concept that exploits a bioenergy source in situ is the
                      plant Microbial fuel cell (MFC). The plant-MFC uses the
                      natural interplay between electrogenic bacteria in soil and
                      plants to convert solar energy into green electricity. The
                      interplay between bacteria and plant is based on the
                      rhizodeposition of organic compounds into the rhizosphere.
                      It is known, that low phosphate (P) content in the soil as
                      well as a high Aluminum (Al) concentration can induce an
                      enhanced exudation of organic compounds by plants into the
                      rhizosphere. However, so far little is known about the
                      factors that influence the rhizodeposition under waterlogged
                      conditions. Thus, the aim of this study was to increase the
                      exudation of several plants into the rhizosphere under
                      waterlogged conditions by treating the plants with low P
                      content or Al addition. Total organic carbon and inorganic
                      carbon analyses indicated that a reduction of P supply
                      induced a twofold increased release of organic compounds in
                      waterlogged Spartina anglica, a threefold in Hemarthria
                      altissima and a fivefold in Glyceria maxima plants. In
                      contrast, the addition of Al did not affect the root
                      exudation of any screened plant species. It is likely, that
                      the screened plants use other mechanisms to detoxify the Al
                      in the nutrient solution such as absorption into the
                      symplasm or pH modifications of the rhizosphere. In future
                      studies it should be tested, if a reduction of P in the
                      plant-MFC is a possible tool to increase the productivity of
                      the plant- MFC without affecting plant development and
