Abstract—Dry anaerobic digestion has several advantages over liquid anaerobic digestion. However, the digestion would be inhibited at low C/N ratio of substrate such as swine manure. In this study, we tried to prevent the inhibition by adding rice straw into swine manure. Swine manure was co-digested with rice straw in semibatch digesters at 8 (manure only), 20 and 30 of C/N ratio. In only C/N 8, NH4+ concentration exceeded threshold (3000 mg N kg w.w.−1) of ammonia inhibition. Methane production of C/N 8 and C/N 20 decreased during incubation, while C/N 30 showed stable CH4 production. Pyrosequencing results showed that the halophilic bacterial communities were altered to non-halophilic ones by co-digestion of manure with straw. In terms of archaea, acetoclastic methanogen was dominated in C/N 20 and 30. Therefore, adding rice straw into swine manure is effective for prevention of the inhibition and related to structure of microorganisms.
