Provide a kind of method for the gramineous straw that ferments.This includes sugarcane, sorghum and maize straw.The method is when these stalks are immersed in water-based reagent solution between the rolls by between the 20% of straw compression to its diameter and 90%.This causes these stalks to rupture in the axial direction, without significantly loss juice, while the reagent solution is pulled in parenchymal tissue in caused fracture network.In some variations, the water-based reagent solution contains fermenting organism, and sugar is spread from parenchyma cell, contacted with these fermenting organisms in these cracks of these stalks, and ethanol and lactic acid are produced in these stalks.In some variations, the combination of enzyme, acid and Fenton reagent diffuses into and the lignocellulosic matrix in these stalks of degrading in the water-based reagent solution.
