山西老陈醋大曲微生物生态分布

应用微生物学的方法,对山西老陈醋大曲进行了微生态研究。试验结果表明,山西老陈醋大曲具有独特的微生物分布。山西老陈醋大曲中心毛霉为主,多达1 4×108g/曲,有少量红曲霉,3 1×106g/曲,假丝酵母和汉逊酵母较多,分别为8 72×107g/曲、8 71×107g/曲;山西老陈醋大曲边角犁头霉和毛霉为主,分别为2 84×108g/曲、3 72×108g/曲,假丝酵母、汉逊酵母、拟内孢霉也较多,分别为4 02×107g/曲、3 89×107g/曲、5 19×107g/曲,醋酸菌也较多,6 91×105g/曲;山西老陈醋大曲表面毛霉、犁头霉为主,分别为2 23×108g/曲、2 19×108g/曲,假丝酵母较多,1 33×108g/曲,醋酸菌在表面最多,可达7 83×107g/曲。研究还发现:大曲由里向外,微生物群体死亡率呈下降趋势、有害霉菌污染程度呈上升趋势,乳酸菌、芽孢细菌呈下降趋势。

Ecological Distribution of Microbe in Shanxi-Super-Vinegar Daqu

This test applies microbiological ways to study the ecological distribution of microbe of Daqu.The results showed that Shanxi-super-vinegar Daqu exists special distribution of microbe. Daqu's core exists more Mucor 1.41×10~(8) g/Daqu,lessMonascus,3.1×10~(6) g/Daqu,and moreCandida,Hansenula,seperately 8.72×10~(7) g/Daqu、8.71×10~(7) g/Daqu;Daqu's edge and corner exist more Mucor andAbsidia, seperately 2. 84×10~(8) g/ Daqu、3. 72×10~(8) g/ Daqu,CandidaEndomycopsis Hansenula Vinegar bacteria are also more, seperately 4.02×10~(7) g/Daqu、3.89×10~(7) g/ Daqu、5.19×10~(7) g/ Daqu、6.91×10~(5) g/ Daqu; Daqu's surface exists more Mucor Absidia Candida, seperately 2. 23×10~(8) g/Daqu、2.10×10~(8) g/ Daqu、 1. 33×10~(8) g/ Daqu,and Vinegar bacteria is the most in entire Daqu.The study also showed that mold pollution is up,and the death rate of microbe ,Lactobcillaceae,Bacillus are down,along with nearing Daqu's surface.
