ethanoltype sludge fermentation recently attracted much attention enhance direct interspecies electron transfer thus improve anaerobic digestion waste activated sludge paper enhancement shortterm ethanoltype fermentation via adding saccharomyces investigated experimental results show maximum ethanol production 10308 206 mgl achieved optimum fermentation conditions ph 51 temperature 260 time 80 hr although content volatile fatty acid vfa increased within 10 hr one order magnitude lower content ethanol indicating vfa generation affect efficient production ethanol analyses changes microbial community fermentation process demonstrate greatest saccharomyces activity occurred first 8 hr play important role ethanol production even low relative abundance meanwhile typical acidproducing bacteria inhibited hydrogenotrophic methanogens ie methanobacterium enriched certain extent statistical analyses reveal rhodobacter thermomonas terrimonas saccharomyces responsible ethanol production fermentation however findings provide reference development enhancing ethanoltype fermentation sludge also expected provide new way thinking efficient bioenergy resource recovery sludge
