The mashed cassava tubers were macerated with 0.2% pectinase by incubating at 40℃ for 6 hr. The degree of maceration was dependent on the enzyme concentration and incubation time. The reducing sugar did not increase even if the macerated mashes were incubated with α-amylase and glucoamylase at pH4.5 and 40℃. The macerated mashes were liquefied with α-amylase by heating at low temperature (80℃ for 10min). The most favorable temperature for the liquefaction of mashes with α-amylase was 75-80℃. The liquefied mashes were almost completely saccharified with glucoamylase at pH4.5 and 40℃ for 12 hr of incubation. Ethanol fermentation of saccharified mashes was carried out with baker's yeast at pH 5.5 and 30℃. The ethanol produced in 48hr fermentation was 16.0-16.5% (v/v), and 65.4g of ethanol was obtained from 500g of cassava tubers.","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/20.500.12000/3906"}]},"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.
