PROBLEM TO BE SOLVED: To provide a further method for utilizing sake cake.SOLUTION: Provided is a method for producing lactic acid fermented sake cake fermentation extract comprising: subjecting a sake cake to amylolytic enzyme treatment and/or proteolytic enzyme treatment as well as to fermentation treatment by yeast, followed by carrying out solid-liquid separation to remove solid components, to produce a sake cake fermentation extract and further subjecting the obtained sake cake fermentation extract to fermentation by a microorganism of the genus Lactobacillus. Also provided are the obtained lactic acid fermented sake cake fermentation extract, and a novel microorganism usable in the present production method.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】酒粕のさらなる利用法を提供する。【解決手段】酒粕をデンプン分解酵素処理および/またはタンパク質分解酵素処理、ならびに酵母での発酵処理に供し、次いで、固液分離を行って固体成分を除去することにより得られる酒粕発酵エキスを、さらにラクトバチルス属の微生物による発酵に供することを含む、乳酸発酵酒粕発酵エキスの製造法を提供する。また、得られた乳酸発酵酒粕発酵エキス、本製造法に利用可能な新規な微生物も提供する。【選択図】なし
