“…Anaerobic digestion is a biological process wherein diverse group of microorganism convert the complex organic matter into a simple and stable end products in the absence of oxygen. This process is very attractive because it yields biogas, a mixture of methane (CH 4 ) and carbon dioxide (CO 2 ), which can be used as renewable energy resources [5][6][7][8]. The anaerobic digestion process can be divided into wet (<10% TS), semi-dry (10-20% TS), and dry (>20% TS) digestion processes depending on the total solid (TS) concentration of the feedstock [9].…”

The aim of this study was to evaluate the effect of biogas slurry inoculation on semi-dry anaerobic co-digestion of swine manure and rice straw, focusing on biogas production and kinetics. Biogas slurry from digested swine manure was applied as inoculum, and the effect was evaluated in batch reactors. The results indicated that biogas slurry inoculation could increase biogas yield by 3.00-7.05%, and improve biogas productivity by 7.48-8.17%, for per unit of TS. The digestion process fitted the single-stage first-order model well, and the reactors inoculated with biogas slurry exhibited faster in biogas production with the biogas production rate constant (k) increased by 39.90-50.96% compared to the control reactor.
