Enhancement in biohydrogen and methane generation from kitchen waste by acetogenic bacteria during solid phase anaerobic digestion

Abstract

The present research is aimed at extraction of energy in terms of newlinebiohydrogen and methane from the kitchen waste through high solids newlineanaerobic digestion Laboratory studies were conducted by varying the total newlinesolids concentration from 20 to 30 under controlled 28oC 5oC and newlineambient 37oC mesophilic condition Maximum methane yield of newline2967 mL CH4 gVS added and VS degradation of 62 was obtained at 20 TS newlineconcentration Significant difference was not found in the methane generation newlineunder controlled and ambient mesophilic temperature conditions newline newline
