Progress review on degradation mechanism of structural carbohydrate by rumen microbes

There are abundant species and a large number of rumen microbes in ruminant，these microbes, including bacteria，fungi and protozoa, play a crucial role for degradation of structural carbohydrate. The bacteria and fungi have stronger ability for degrading structural carbohydrate，they could loose the compact texture of structural carbohydrate by adhesion and penetration，and then degrade structural carbohydrate to monosaccharide by enzymes function. The monosaccharide could be utilized by ruminant through rumen microbes. Many factor, such as plant epidermis，physical and chemical characteristic of cell wall，composition of cell wall，rumen environment and other nutrients, could affect the degrading process.
