摘　　要：为了解盐渍肠衣发生红变的原因,利用嗜盐菌及嗜盐菌选择性培养基,采用平板划线分离法反复分离纯化,从发生盐红现象的肠衣中分离得到1株产红色素的菌株,通过形态学、生理生化鉴定,初步鉴定为盐杆菌属(Halobacteri-umsp.)。In order to get the reason of red change in salted casing,a strain that produces red pigments was isolated from the red salted casings after repeated streak plate and purification,through halophilic bacteria and halophilic bacteria selective medium.Based on morphological,physiological and biochemical tests,the strain was identified as Halobacterium sp.
