Lignocellulose biorefining has great potentials of feedstock supply and product market in the major agricultural countries such as USA, China, India, Brazil etc.However, severe technical barriers of the present biorefining processes exist and the cost for cellulosic ethanol production is still greater than the acceptable market range.Cutting the processing cost of cellulosic ethanol to a profitable level is crucially important to survive the lignocellulose biorefinery industry from the current dilemma.
