Title：Mend in bifidobacterium medium
Abstract
Bifidobacterium is an obligate anaerobes.With this kind of germ,varieties of carbohydrate could be fermented to form acetic acid and lactic acid.As a result,the pH value of colon is decreased,and the other pathogenic bacterium could be depressed as well as the repeated adsorption of ammonia is reduced .The bifidobacterium is an acid-sensitive germ.When the pH value is belw 5,the bifidobacterium growth would be significantly depressed.In this study,GAM mediums modified by variable concentration of lactulose solution are used to observed the growth of bifidobacterium.When the concentratiion of is more than 4%,the colony of bifidobacterium is reduced sinificanly and the pH value of the medium is below 5. The impact of the text discuss vary on mend GAM upper join pH indicator lactulose versus Bifidobactirium growth status，from among fish out lead cola ph GAM at what strain scope talent brought ammoniac drink in as well as decrease up to，the growth again are free from to had a strong impact on of the whereas Bifidobactirium。
