In this study, methanogenic reactor was operated along with the shift of hydraulic retention time (HRT) at 35 oC. In the methanogenic stage, COD was reduced by 65.8 (± 1.1)% compared to a 47.4 (± 2.9)% reduction in VS reduction efficiency, indicating the gradual increase in methane production and the gradual decrease in methane yield during a HRT between 25 and 10 days. This was probably due to the fact that methanogens consume a substantial amount of the VFAs produced as a result of the degradation of major organic materials by bacteria. Through denaruting gel gradient electrophoresis (DGGE), Methanoculleus bourgnesis, belonging to Mehtanomicrobiales (MMB) was predominant during a HRT between 25 and 10 days, while Methanobrevibacter sp. AbM4, belonging to Methanobacteriales (MBT) was predominant during a HRT between 10 and 5 days. Overall 16S rRNA gene concentration also gradually decreased with decline of HRT. Redundancy analysis was also carried out n order to understand correlation between methanogenic community and environmental variables.
