Abstract: Yak mainly lived in the Qinghai-Tibetan plateau in Qinghai province of China and lived on grasses.Many studies had shown that yak's ability to digest cellulose was far higher than Yellow cattle and dairy cows.Because there were significant differences in the rumen microorganisms among these three kinds of animals.There was a large microbial population in the yak rumen that could degrade cellulose.In this paper,the characteristics of microorganism,influence factor and the mechanism of cellulose degradation in yak were summarized.In addition,the brief introduction of the yak rumen microbial's possible applications had carried on in order to provide theoretical basis and strengthen the use of cellulose degradation bacteria in the areas such as modernization of traditional Chinese medicine fermentation and so on.

Key words: yak; rumen microorganism; metabolism of cellulose; application; traditional Chinese medicine fermentation
