PROBLEM TO BE SOLVED: To provide a culture medium for cultivating mushroom solving the following problem: sawdust powder or corn cob is becoming hardly available at a low price in a conventional culture medium for cultivating mushroom using sawdust powder or corn cob as a main material.SOLUTION: The culture medium is produced for cultivating mushroom fungi which is obtained by inoculating fungi into a humidity-conditioned sample prepared by adding 10 g of distilled water to a sample having dry weight of 5 g and comprising leaves and stalks of sorghum except for seeds thereof to adjust humidity of the sample, and culturing the fungi-inoculated sample for three weeks while keeping it to have a temperature of 20°C, so that the weight of the sample is reduced by &ge20 wt.%. The culture medium is mixed with pulverized material obtained by pulverizing the leaves and the stalks of sorghum, and is sterilized with steam.COPYRIGHT: (C)2011,JPO&INPIT【課題】主材としておが粉やコーンコブを用いた従来のきのこの栽培用培地では、おが粉やコーンコブが安価に入手できなくなりつつあるという課題を解決する。【解決手段】ソルガムの実を除く葉と茎とから成る乾燥重量5gの試料に対し10gの蒸留水を加えて調湿した調湿試料に植菌し、温度20℃に保持して3週間培養したとき、前記試料の重量減が20重量%以上となるきのこ菌を栽培する培地であって、前記培地は、ソルガムの葉と茎とを粉砕した粉砕物が配合され、且つ蒸気殺菌が施されている。【選択図】なし
