摘要
用丢糟代替部分豆粕改良酱油种曲培养基,通过试验确定丢糟的最佳添加量为25%,曲盘厚度3cm,培养时间为72h,所制得的种曲孢子数为2.7×1012个/g,蛋白酶活力为1104.2u。
The waste distiller＇s grain was used to replace part of soy bean to improve the culture medium of seed starter of sauce. The relative technical parameters were determined through experiments as follows： addition level of waste distiller＇s grains as 25 %, the thickness of starter cake as 3 cm, 72 h culture time, and the spore number of the produced seed starter as 2.7×10^12cf/g and its proteinase activity is 1104.2 u.
