Utilization of multi-specie feedstocks is imperative for application of lignocellulosic biorefineries in arid regions. Different lignocellulosic residues vary in composition and anatomical features. Pretreatment and enzymatic hydrolysis are two processes at the front end of any lignocellulosics biorefinery applying biochemical pathway, and have to efficiently deal with the variance in the feedstock composition and properties. However, there is limited knowledge about effect of mixing different lignocellulosics on pretreatment and enzymatic hydrolysis yields. In this study effect of mixing on the yields from hydrothermal pretreatment and enzymatic hydrolysis was analyzed by mixing three different lignocellulosic residues - Bermuda grass, Jasmine hedges, and date palm fronds. Results showed that the individual and the mixed lignocellulosics gave same yields when treated under similar conditions of hydrothermal pretreatment and enzymatic hydrolysis. It indicates that this mixture can be a suitable feedstock for lignocellulosic biorefinery.
利用多物种原料对于在干旱地区应用木质纤维素生物精炼厂是必要的。不同的木质纤维素残余物在成分和解剖特征上有所不同。预处理和酶解是任何木质纤维素生物精炼厂应用生化途径的前端过程，必须有效地处理原料成分和性质的差异。然而，关于混合不同木质纤维素对预处理和酶解产率的影响的知识有限。在这项研究中，通过混合三种不同的木质纤维素残余物——百慕大草、茉莉树篱和枣椰树叶，分析了混合对水热预处理和酶解产率的影响。结果表明，在相似的水热预处理和酶解条件下处理时，单独和混合的木质纤维素产生相同的产率。这表明这种混合物可以作为木质纤维素生物精炼厂的合适原料。
