PROBLEM TO BE SOLVED: To provide culture medium for cultivating mushroom obtained by utilizing fermentation technique to reduce cost for coping with prevention of foul smell due to decay of waste mushroom culture medium so as to inexpensively produce the mushroom and appropriately grow the mushroom.SOLUTION: The culture medium for cultivating mushroom comprises blended culture medium for mushroom cultivation where material obtained by using the waste mushroom cultivation medium wasted in an artificial cultivation of mushroom is partly blended. Fermented material obtained by fermenting the waste mushroom culture medium with useful bacteria and drying the fermented waste culture medium at least until the breeding of the useful bacteria gets slow so as to reduce the moisture content, is blended as part of the nutritious material for the mushroom culture medium. The culture medium enables drastic reduction in expensive nutritious material and thereby results in cost reduction.COPYRIGHT: (C)2011,JPO&INPIT【課題】発酵技術を利用してきのこ廃培地の腐敗による悪臭防止などの処理コストを低減させて安価に生産でき、且つ適切にきのこを育成できるきのこ栽培用培地を提供すること。【解決手段】きのこの人工栽培において廃棄される菌床であるきのこ廃培地を原料とする資材が、一部に配合されているきのこ栽培用の配合培地であって、前記きのこ廃培地を有用菌によって発酵させて、少なくとも前記有用菌の繁殖が鈍化するまで含水率を低下させるように乾燥させて得られる発酵資材が、きのこ培地の栄養資材の一部として配合されている。高価な栄養資材の大幅な削減を可能とし、低コスト化が図れる。【選択図】図1
