Abstract A continuous anaerobic co-digestion experiment of 55days was carried out under the condition of 55 by℃ using a mixture feeding of 8% in total solid (TS). Food waste mixed with straw (TS of 1:1) was used as feeding materials, and the hydraulic retention time (HRT) was set at 5, 3, 1.5, 1 and 0.5 days. Corresponding with OLR were 8.0, 6.66, 3.33, 5.0 and 5.0 g VS/(L·d). Then, the microbial composition was analyzed. When the HRT was shortened from 5d to 1d, the reactor was stable. The OLR, VS removal rate, gas production rate and volumetric gas production rate were maintained at a high level. When the HRT was reduced to 0.5d, the pH was stable at about 7.0, and VFA was not overload. But the reactor almost stopped producing gas. The VS removal rate was only 5.77%, the microbial was loss. At the same time, high-throughput test results showed that, when HRT was 0.5d, the proportion of Hydrogenated methanogens increased, acetoclastic methanogenesis were down to 0.6%, and the proportion of acetogenesis bacteria like Clostridiales increased nearly, acetic acid oxidase and hydrogentrophic methanogenic bacteria may be the main pathway of acetic acid utilization.
