The methane fermentation was carried out at 37℃ and 7.5 of pH in a 200-mℓ syringe containing the sludge which was acclimated to the same substrate, and evolution and composition of the gas, volatile fatty acids and pH were measured. A good gas production from the substrate was observed when water content in the mash was higher than 84% (v/v). The optimum pH range and temperature of the mash for methane fermentation were from 7 to 8 and 37℃, respectively. The total gas evolved was 402mℓ per g of substrate with a methane ratio of 54% in 30 days of fermentation. Acetate, propionate and n-butyrate were accumulated in the mash in early stages of fermentation and decreased during fermentation process. The biodegradation of cellulose in the materials amounted to 60% in 30 days of fermentation. The gas production from the alkali-treated sugar-cane top&laeves was 1.3 times higher than that from the untreated materrials.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3843"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
