Anaerobic digestion is a widely accepted method to treat wastes such as peanut shell. The energy and nutrients are simultaneously recovered by this method. The objective of this study was to elucidate the effect of TiO 2 nanoparticles in co-digestion of hybrid Pennisetum and peanut shell under mesophilic conditions. The results demonstrated the methane (CH 4 ) production was improved by adding the TiO 2 nanoparticles. The cumulative gas production is best (up to 11,133.3 mL) by adding 0.15% nano-TiO 2 particles. The microbial community analysis showed that Methanobacterium and Methanosarcina were enriched in the presence of TiO 2 nanoparticles indicating that TiO 2 can improve CH 4 production by stimulating the growth of methanogens.
