Zusammenfassung:	To provide yeast culture media for enabling mass culture of yeast and industrialization by using a substitute of a yeast extract where the substitute is easy to obtain, cheap and provides yeast proliferation and productivity same as or better than the culture with the yeast extract.SOLUTION: Disclosed is a yeast culture medium characterized by using bean card refuse or a liquid extract thereof in place of a yeast extract. Also there is provided a method for culturing yeast comprising the steps of: pre-culturing yeast in a medium containing bean curd refuse in place of the yeast extract; culturing the precultured yeast in a main culture medium containing bean curd refuse in place of the yeast extract; and then removing the bean curd refuse from the culture medium.SELECTED DRAWING: Figure 1 【課題】入手しやすく、価格も安く、酵母エキスで培養した場合と同等もしくはそれ以上の増殖能や産生能が担保された代替品を用いることで、酵母の大量培養を可能とし、ひいては工業化への道筋をつけることを目的とする。【解決手段】酵母培養培地であって、酵母エキスの代わりにおから又はおから抽出液を用いることを特徴とする、酵母培養培地を提供する。また、酵母の培養方法であって、酵母エキスの代わりにおからの入った培地で前培養する工程と、前記前培養した酵母を、酵母エキスの代わりにおからの入った培地で本培養する工程と、本培養培地からおからを除去する工程と、からなる酵母の培養方法を提供する。【選択図】図１
