摘要	This study investigated the effects of 12.6 psi (T1), 6.3 psi (T2), 3.3 psi (T3) and ambient (T4) headspace pressure on the metabolic pathways in the acidogenic leach bed reactor (LBR) and overall methane recovery during two-phase anaerobic digestion of food waste. Diversion of biogas from LBR enhanced COD and soluble product generation in T2, T3 and T4 whereas, high pressure (T1) resulted in comparatively higher lactate production and low protein degradation. A pressure of 3-6 psi (T2 and T3) improved the production of COD by similar to 22-36%, soluble products by similar to 9-43%, volatile solid reduction by similar to 14-19%, and CH4 production by similar to 10-31% compared with control. Besides, similar to 3-6 psi headspace pressure positively influenced the composition of soluble products resulting in enhanced methane recovery adding advantage to the two-phase system. A headspace pressure of similar to 3-6 psi is recommended to enhance the hydrolysis-acidogenesis; however, the actual hydrogen concentration should be considered.
