A comprehensive study was carried out to assess the effectiveness of solar assisted alkali pretreatment (SAAP) on garden biomass (GB). The pretreatment efficiency was assessed based on lignocellulose degradation, conversion of cellulose into reducing sugars, changes in the ultra-structure and functional groups of lignocellulose and impact on the crystallinity of cellulose, etc. SAAP was found to be efficient for the removal of lignin and hemicellulose that facilitated enzymatic hydrolysis of cellulose. FTIR and XRD studies provided details on the effectiveness of SAAP on lignocellulosic moiety and crystallinity of cellulose. Scanning electron microscopic analysis showed ultra-structural disturbances in the microfibrils of GB as a result of pretreatment. The mass balance closer of 97.87% after pretreatment confirmed the reliability of SAAP pretreatment. Based on the results, it is concluded that SAAP is not only an efficient means of pretreatment but also economical as it involved no energy expenditure for heat generation during pretreatment.
进行了一项综合研究，以评估太阳能辅助碱预处理 (SAAP) 对园林生物质 (GB) 的有效性。根据木质纤维素降解、纤维素转化为还原糖、木质纤维素超结构和官能团的变化以及纤维素结晶度的变化等方面来评估预处理效率。发现 SAAP 可以有效地去除木质素和半纤维素，从而促进纤维素的酶水解。FTIR 和 XRD 研究提供了关于 SAAP 对木质纤维素部分和纤维素结晶度的有效性的详细信息。扫描电子显微镜分析表明，预处理导致 GB 微纤维的超结构紊乱。预处理后质量平衡接近 97.87%，证实了 SAAP 预处理的可靠性。基于这些结果，可以得出结论，SAAP 不仅是一种有效的预处理方法，而且经济，因为它在预处理过程中不涉及产生热量的能源支出。
