AB  - Microbial electrolysis cell (MEC) was integrated into conventional anaerobic 
      digestion (AD) system (i.e. MEC-AD) to electrochemically regulate the 
      co-fermentation of food waste (FW) and sewage sludge (SS). Two anaerobic systems 
      (i.e. MEC-AD, and single AD) were operated in parallel to explore the potential 
      stimulation of electrical regulation in metabolic behaviors of FW and SS and 
      subsequent biomethane production. The highest accumulative methane yield was 
      achieved at an applied voltage of 0.4 V and the FW and SS ratio of 0.2:0.8, 
      increasing by 2.8-fold than those in AD. The combined MEC-AD system mitigated 
      N(2)O emission and considerably improved ammonia removal and the dewaterability 
      of digestate, in contrast to AD. Scanning electron microscope (SEM) visualized 
      the presence of a large number of rod-like and cocci-like electroactive microbes 
      on the electrode surface. Electrical regulation stimulated the self-growth and 
      proliferation of typical Methanobacterium and Methanosaeta, accordingly 
      contributing to biomethane production greatly.
