摘要
不同地区的绿衣观音土曲和母曲中微生物均表现出较高的一致性,酵母菌和霉菌数量的分布情况因曲而异。微生物类群主要为霉菌、棒曲霉、酵母、放线菌和细菌。绿衣观音土曲中根霉是主要的糖化菌;酵母菌主要代谢生产酒精;细菌可增加酒中风味物质,但若含量过大会影响酒风味的协调;棒曲霉在发酵中产风味物质,酯化生成乳酸乙酯。(丹妮)
Microbes in green-covering-guanyintuqu and in maternal starter in different regions manifested high unanimity. And the quantity distribution of microzyme and mildew varied to different starter species. The microbe groups mainly included mildew, aspergillus claviform, yeast, actinozyceto and bacteria and their functions are as follows: rhizopus as the main saccharifying strains; microzyme as the main microbe producing alcohol; and bacteria could increase flavoring substances in liquor, however, excessive bacteria content would adversely influence the harmony of liquor taste; aspergillus claviform produced flavoring substances during fermentation mainly as ethyl lactate.
