The treatment with 5% sodium perchlorate, 5% sodium chlorate, 35% peroxide : acetate (1 : 1) and 0.5% sodium hydroxide significantly increased the degradability and resulted in loss of weight in the range from 34 to 60% of original material. Pretreatments with 0.5 to 1.0% sodium hydroxide found to be effective for increasing its susceptibility to enzymatic hydrolysis. The alkali-treated materials were almost completely degraded by cellulase preparation in 48 hr of incubation. The degree of weight loss by pretreatment with sodium hydroxide was dependent on the concentration of reagent. Susceptibility of 0.5% sodium hyroxide-treated materials to hydrolysis action of the enzyme increased in proportion to the rise in temperature of pretreatment. The rate of saccharification of 0.5% sodium hydroxide-treated materials by the enzyme decreased with an increase in concentration of substrate.","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/20.500.12000/3815"}]},"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.
