摘要
试验以山西老陈醋醋厂发酵正常的醋醅为试验样品,对其中的醋酸菌采用了变色圈法进行分离,再经过初筛、复筛,根据产酸量高低得到了5株优势醋酸菌(AbT,Af10,Af5,Au13,Af20)。通过对这5株优势菌株的个体形态、培养特征、生理生化特性的研究,将其鉴定为醋酸杆菌属中的巴氏醋杆菌(Ab7)、醋化醋杆菌(Af10)、液化醋杆菌(Af5)、汉氏醋杆菌(Au13)和恶臭醋杆菌(Af20)。通过本试验的研究可为山西老陈醋的进一步发展奠定菌种基础。
The normal solid-fermenter of Shanxi Super-Mature Vingar factory is tested in this experiment. As to its inside acetobacter acetic, adopting the changing colour circle method to separate acetobacter acetic,then through early screening and second screening, finally according to the quantity of producing acid the author got five superior acetobacter acetics. The morphology, cuLtivation, physiology, biochemistry were tested for identification.In the end,five superior strains all belong to Acetobacter.Ab_(7) was characterized as A.rancens,Af_(5 )as A.Liquefaciens,Af_(20 )as A.rancens,Af_(10) as A.aceti,and Au_(13) as A.hansenii.
