This invention discloses a method for producing fuel ethanol from a straw fibre raw material, comprising: (1) raw material selection; (2) disintegration; (3) pre-processing; (4) double-enzyme saccharifying; (5) sterilization; (6) enlargement culture and application of Pachysolen tannophilus P-01; (7) fermentation; (8) distillation; characterizing: the pre-processing employs white-rot fungi solid culture to decompose lignin. The procedures comprise: (1) bacterium: Coridus versicolor; (2) crude laccase production: (1) culture media producing condition,(2) fermentation: inoculate 6 parti-color Coriolus versicolor seed stopper per 1000ml, 28-30Deg C, 150rpm shake culture for 7d, remove the hypha by filtration so as to obtain the crude laccase; (3) crude peroxidase production: i. culture media, ii. fermentation: inoculate 6 rings of Phanerochete chrysosporium spores per 100ml, 37-39Deg C, static culture for 9d, remove hypha by filtration so as to obtain crude peroxidase; (4) conditions of enzyme liquid decomposing straw: add 1ml crude peroxidase and crude laccase respectively to the straw powder and mix homogenously, and then decompose the straw at 45Deg C, pH 4.5 for 72h. This invention can improve the ethanol yield and decease cost.
