自然发酵条件下柿子原浆果醋中优势醋酸菌的分离与鉴定

以自然发酵的柿子原浆果醋的醋醅为试验材料,对其中的醋酸菌以变色圈法进行分离,再经过初筛、复筛,依据产酸量得到1株优势醋酸菌。通过对这株优势菌株的个体形态、培养特性进行观察,并结合其生理生化特性,鉴定该菌株为醋酸杆菌属中的巴氏醋杆菌(Af6)。

Separation and Identification of Superior Acetic Acid Bacteria from Persimmon Virgin Pulp Vinegar at Natural Fermentation Condition

The solid-fermenter of Persimmon virgin pulp Vinegar with natural fermentation as test material(was tested in this experiment). Adopting the changing colour circle method to separate acetic acid bacteria, then through primary screening and second screening, finally according to the quantity of producing acid one superior acetic acid bacteria was obtained. The morphology, cultivation, physiology, biochemistry were tested for identification. In the end, this superior strain belongs to the Acetobacter. Af6 was characterized as A. rancens.
