Under the conditions employed in the present research the results are summarized as follows : Pressure and time increased alcohol extractives. Delignification and relative cellulose content was also increased by pressure treatment though holocellulose content was decreased by the factor. All three factors had significant effect on hemicellulose content (loss in KOH solution). Two way interactions between pressure and NaOH were found in alcohol extractives, delignification, holocellulose content and cellulose content. Negative correlations of sample recovery were observed with alcohol extraction, delignification and cellulose content but positive with holocellulose and cellulose contents. All these results clearly indicate that structure of bagasse material was chemically and physically altered by the treatment applied in this experiment. It was also found that the effect of pressure on the criteria studied was greater than NaOH and duration of the treatment.","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":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4169"}]},"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.
