Energy is an important influencing factor of economical development

and the inverting lignocellulosic into ethanol provides a favorable solution for continuable energy.The process of the inverting lignocellulosic into ethanol mostly include pretreatment、enzymatic hydrolysis and fermentation

in this paper new development in the process of the biotechnology are reviewed

and the paper indicate that the enzyme immobilization、genetically engineered microorganism and others largely promote the industrialization course of the lignocellulosic

and the future is bright.
