Abstract

Canned bamboo shoot residues of Phyllostachys prominens consists of bamboo shoot sheath (culm leaf) and bamboo shoot (culm). Bamboo shoot (culm) was rich in protein ( 20. 6% ) and poor in lignin ( 2. 7% ); bamboo shoot sheath ( culm leaf ) contains protein ( 12. 3% ), cellulose( 32. 8% ), pentosan ( 25. 0% ) and lignin( 13. 9% ). Dilute H2SO4 prehydroly sed bamboo shoot sheath was used as carbon source in cellulase production by Trichoderma reesei Rut C30. After 5 days, obtained enzyme solution had a FP active of 1. 9 IU mL- 1 and cellulase production residue was more proteinous ( 25. 4% protein) than shoot sheath. Dilute H2 SO4 prehydrolused bamboo shoot residues used as subst rate, enzyme-subst rate ratio 12 IU g- 1 dry residues. The yield of enzymatic hydro lysis could reach 80. 1% ( culm leaf ) and 82. 0% (culm) . The sugar solution of prehydrolysis and enzymatic hydrolysis could be used to produce yeast. The residues of cellulase production and enzymatic hydrolysis increased in feed value.
