Description
洗米排水に沈降性及び自己凝集性を有する酵母を混合し、
曝気により攪拌させるとともに好気条件にして18〜48時間の培養を行い、嫌気性微生物の繁殖を抑制して前記嫌気性微生物による前記洗米排水に含有する固形成分の分解を抑制しつつ、前記酵母と前記固形成分との接触頻度を高めて前記固形成分を前記酵母に付着させ、
その後、1〜3時間静置することによって自己凝集性による前記酵母同士のフロックの形成によって沈降を促進させて前記固形成分を前記酵母と共沈させる、
ことを特徴とする。
通気量:1vvm(1L air/L洗米排水/min)、
pH無調整(使用した洗米排水のpH6.0〜6.2)
培養温度:30℃
