Secondly, Bifidobacterium medium was developed using JAJ as main material. The results showed that: Adding Tryptone,soy peptone.beef extract,com extract and Cys-HCl to JAJ could obviously promote the growth of Blm and Bbm;By the orthogonal experiment of three elements and three levels,a satisfying JAJ compound medium was acquired which included corn extract(0.3%), soy peptone(0.05%)and Cys-HCl(0.025%).Nextly,after establishing a selective Bifidobacterium medium, the effects of JAJ on the growth of Bifidobacteria in vivo were studied,using healthy mouse of Kunming species as experimental animal.
