Addition of calcium carbonate to the acclimated sludge containing a large quantity of substrate found to be effective for gas production in the mesophilic methane fermentation. The gas production increased with an increase in organic matter of stillage, however, the volatile fatty acids were significantly accumulated in the mash when the amount of loading was more than 0.9g of organic matter of stillage. The maximum loading of substrate on anaerobic fermentation in the presence of calcium carbonate was about 3 times higher than that of control. The whole gas production was 696ml per g of organic matter of stillage and methane ratio was 69%. The COD value of the mash rapidly decreased in the early stage of fermentation and achived from 8,000 to 30ppm in 8 days of incubation. Gas production in continuous methane fermentation was about 500ml per g of organic matter of stillage with a methane ratio of 61%.","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/20.500.12000/3814"}]},"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.
