摘要
第二代乙醇是利用酶作为催化剂,主要是木聚糖酶,从木质纤维素生物质的降解中生产出来的。这些生物催化剂通常价格昂贵,但在高温下稳定,并且它们的重复使用具有很大的价值,因此固定化酶可以增加它们在工业规模上的应用。本研究试图将富含真菌Fusarium sp. EA 1.3.1产生的木聚糖酶的鸡尾酒固定在海藻酸盐球中,优化了固定方法,对固定衍生物进行了表征,改善了它们的物理化学特性,并实现了蔗渣的水解,并且在与缀合物的反应中获得了更多的还原糖。因此,由真菌Fusarium sp. EA1.3.1产生的富含木聚糖酶的混合物成功地固定在海藻酸盐球上,并具有作为工业过程催化剂的潜力,如木质纤维素乙醇工业。
Immobilization in Spheres of a Cocktail Rich in Xylanase Produced by the Fungus Fusarium sp. EA 1.3.1 for Hydrolysis of Sugarcane Bagasse
Second generation ethanol is produced from the degradation of lignocellulosic biomass using enzymes as catalysts, with emphasis on xylanases. These biocatalysts are often costly, but stable at high temperatures, and their reuse is of great value, so the immobilization of the enzymes can increase their appli-cability on an industrial scale. We sought to immobilize a cocktail rich in xylanase produced by the fungus Fusarium sp. EA 1.3.1 in alginate spheres, op-timize the immobilization method, characterize the immobilized derivatives, improve their physical-chemical characteristics, and perform the hydrolysis bagasse was achieved, and greater amounts of reducing sugars were obtained in the reaction with the conjugate. Thus, the cocktail rich in xylanase produced by the fungus Fusarium sp. EA1.3.1 was successfully immobilized on alginate spheres and possesses the potential to be used as a catalyst in industrial processes such as the lignocellulosic ethanol industry.
