Methane production from grape skins. Final technical report
Abstract
Methane production from grape pomace was measured for a 50-day digestion period. Gas production was calculated to be 2400 ft/sup 3//10 d/ton at 53% methane content. Microorganisms particularly a fungus which grows on grape pomace and lignin was isolated. Lignin content of pomace was measured at approximately 60%. Lignin is slowly digested and may represent a residue which requires long term digestion. Research is continuing on isolation of anaerobic methane bacteria and codigestion of pomace with enzymes as cellulase and pectinase. The sewage sludge functioned adequately as a mixed source of organisms capable of digesting grape pomace. A sediment from stored grape juice produced significant amounts of methane and represents a nutrient substrate for additional studies on continuous flow methane production. 3 figs.
