Keyword:  固定化己酸菌窖泥功能菌固定化培养包埋剂;
Abstract: 窖泥已酸菌又名梭状芽孢杆菌,属嫌气性微生物,作为窖泥主要功能菌之一,其与浓香型大曲酒中己酸、己酸乙酯等风味物质的生成密切相关.固定化微生物技术可以提高微生物细胞的浓度,并保持其较高的生物活性,实现反复利用等.本实验以琼脂作为固定化材料,将窖泥己酸菌种子进行包埋固定,将铴的琼脂溶液与己酸菌液1∶1混匀后制成琼脂己酸菌块,以2%的接种量进行接种,培养3天后每天取样对己酸产量进行分析,并考察连续培养过程中的菌种稳定性等.结果表明:琼脂固定化窖泥己酸菌扩大培养6天即可达到传统方法10%接种量扩大培养7天的效果,菌种连续扩大培养6轮次仍然保持较高活性,说明琼脂固定化窖泥己酸菌细胞繁殖快、己酸产量高、产酸稳定性好、可连续发酵等.
