摘要

对麦麸等农业残留物进行酶水解,可使生物技术工艺中原本未使用的碳源价值化。黑曲霉和毛霉以麦麸颗粒为底物进行共培养,可产生由木糖酶、淀粉酶和纤维素酶组成的酶集,适合将木质纤维素生物质降解为糖单体(D-葡萄糖、D-木糖和 L-阿拉伯糖)。通过在搅拌罐生物反应器中进行酶制剂生产和水解的一体化单锅工艺,在 25 升和 1000 升的规模下,水解产物的总糖浓度在 86 小时内分别达到 32.3 克/升和 24.4 克/升。

Valorization of Wheat Bran by Co-Cultivation of Fungi with Integrated Hydrolysis to Provide Sugars and Animal Feed
The enzymatic hydrolysis of agricultural residues like wheat bran enables the valorization of otherwise unused carbon sources for biotechnological processes. The co-culture of Aspergillus niger and Trichoderma reesei with wheat bran particles as substrate produces an enzyme set consisting of xylanases, amylases, and cellulases that is suitable to degrade lignocellulosic biomass to sugar monomers (D-glucose, D-xylose, and L-arabinose). An integrated one-pot process for enzyme production followed by hydrolysis in stirred tank bioreactors resulted in hydrolysates with overall sugar concentrations of 32.3 g L−1 and 24.4 g L−1 at a 25 L and a 1000 L scale, respectively, within 86 h. Furthermore, the residual solid biomass consisting of fermented wheat bran with protein-rich fungal mycelium displays improved nutritional properties for usage as animal feed due to its increased content of sugars, protein, and fat.
