The tuber-tissue-degrading activity of enzyme was expressed by measuring the amount of residual tissues after degradation. Asp. saitoi enzyme or Meicelase showed a lower activity against the tuber-tissues. With the combined action of two enzymes, however, the tuber-tissues were readily degraded to release glucose and galacturonic acid. The free galacturonic acid was increased during incubation period by the addition of Asp. saitoi enzyme to tuber-tissues and not by that of Meicelase. The combined action of Asp. saitoi enzyme and Meicelase could not accelerate the degradation of pectic substance in the tuber-tissues. Meicelase was found to degrade cellulosic materials in the tuber-tissues, producing high-molecular-weight pectic substances. When Asp. saitoi enzyme and Meicelase were added to the tuber-tissues, reducing sugar and total sugar were increased significantly.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"琉球大学農学部","subitem_publisher_language":"ja"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3875"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0370-4246","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00250548","subitem_source_identifier_type":"NCID"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"琉球大学農学部学術報告","subitem_source_title_language":"ja"},{"subitem_source_title":"The Science Bulletin of the Faculty of Agriculture.
