香猪源性双歧杆菌的筛选及鉴定

摘要

为丰富双歧杆菌（Bifidobacterium，BF）菌种资源，对双歧杆菌保健产品的开发奠定基础，选择贵州省特色资源香猪的粪便进行了双歧杆菌的筛选及鉴定试验。结果表明：从1～6月龄香猪粪便中共分离50个菌株（BF1～BF50），其中，8株（BF15，BF21，BF23，BF28，BF33，BF34，BF37，BF42）为长双歧杆菌，其他42株为猪双歧杆菌。香猪源性双歧杆菌主要形态为表面光滑、菌落微小，乳白色凸起状，边缘整齐且为半透明或不透明状，有V形、L形（较多）、Y形（较少见）。%In order to enrich the resource of Bifidobacterium and lay the foundation for health care products of Bifidobacterium,Bifidobacterium was isolated and screened from the feces of the healthy Guizhou Xiang pigs which were the featured resource of Guizhou .The results showed that fifty strains were isolated from 1 to 6-month-old Guizhou Xiang pigs,42 strains were B.suis,and eight of them were B.longum.Their morphology were mainly as follows,such as smooth surface,tiny colonies,white convex,neat edge and translucent or opaque shape,with V-shaped,L-shaped ,Y-shaped.
