Abstract: Microbial pretreatment technology could remove the hemicellulose and lignin, degrade the cellulose and increase bio-energy conversion efficiency, and also has the advantages of low energy consumption and non-pollution and has better prospect. The microorganisms which were used to pretreat the energy grass,the secreted enzymes during pretreatment process and treatment effect were summarized; and the influencing factors including pretreatment time, pretreatment temperature, microbial inoculation rate, substrate water content, limiting factors about the pretreatment and improvement methods in the process of biological pretreatment procedure were narrated. And it points out that the enetic engineering bacteria and combination pretreatment methods are the key points of the future research.

Key words: energy grass, microbial pretreatment, biofuels, degradation
