摘要

油棕空果串(EFB)是泰国最丰富的农业剩余物之一,是一种有吸引力的增值农产品木质纤维素材料。它们可以作为廉价的可再生原料来生产酸和许多其他增值产品。本研究旨在探讨EFB作为分离水解发酵(SHF)原料的潜力。本研究采用蒸汽爆破法对木质纤维素材料进行预处理。用Cellic CTec2酶(25 FPU/ml)将预处理后的材料水解成葡萄糖。采用基于中心复合设计(CCD)的响应面法(RSM)优化了固体负荷、(nh4) 2so4和na2co3等培养基组成对富马酸浓度的影响。优化后的培养基为(g/L):固载166.70,(nh4) 2so4 0.29, na2co3 3.07。富马酸浓度预测值最大为5.18 g/L,与观测值5.30 g/L相符

Production of fumaric acid from oil palm empty fruit bunch
Oil palm empty fruit bunch (EFB) , one of the most abundant agricultural residues in Thailand , is an attractive lignocellulosic material for value added agricultural products. They could be used as a raw material for cheap renewable feedstock to produce acids and  many other value-added products. This research is to investigate the potential of EFB as a raw material for fumaric acid production through separate hydrolysis and fermentation (SHF) by the selected fungal isolate K20. Steam explosion was used in this study to pretreat  the lignocellulosic material. A Cellic CTec2 enzyme (25 FPU/ml) was used to hydrolyze the pretreated material into glucose. Response surface methodology (RSM) based on central composite design (CCD) was applied to optimize the effect of the medium composition including solid loading, (NH 4 ) 2 SO 4 and Na 2 CO 3 on fumaric acid concentration.  The optimized medium consisted of (g/L): solid loading 166.70, (NH 4 ) 2 SO 4 0.29 and Na 2 CO 3 3.07. The maximum predicted value of fumaric acid concentration of 5.18 g/L was obtained, which corresponded with the observed values of 5.30 g/L
