Alkaline pretreatment of the substrate improved the gas evolution from bagasse. The most favorable concentration of NaOH solution and loading of treated bagasse were 0.5 (w/v) and 0.5g (dry wet.), respectively. The gas production from the alkaline-treated bagasse was 1.8 times higher than that from the untreated bagasse. The total gas evolution from alkaline-treated bagasse was 540ml per g of dry substrate with a methane ratio of 63% in 10 days of fermentation. Acetic, propionic and butyric acids accumulated in the mash after 4 days of fermentation and the decreased gradually during further fermentation. The gas evolution from 5%-NaCIO_2-treated bagasse was 2.1 times higher than that from the untreated bagasse and methane content was 69%. The whole gas evolved from the bagasse components, bagasse holocellulose, -hemicellulose and -cellulose was 560-600ml per g of dry substrate with a methane ratio of 63-67% in 10 days of fermentation.","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/20.500.12000/3890"}]},"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.
