Abstract：
The hydrolysis and biotransformation of lignocellulose, i.e., biorefinery, can provide human beings with biofuels, bio-based chemicals, and materials, and is an important technology to solve the fossil energy crisis and promote global sustainable development. Biorefinery involves steps such as pretreatment, saccharification, and fermentation, and researchers have developed a variety of biorefinery strategies to optimize the process and reduce process costs in recent years. Lignocellulosic hydrolysates are platforms that connect the saccharification process and downstream fermentation. The hydrolysate composition is closely related to biomass raw materials, the pretreatment process, and the choice of biorefining strategies, and provides not only nutrients but also possible inhibitors for downstream fermentation. In this review, we summarized the effects of each stage of lignocellulosic biorefinery on nutrients and possible inhibitors, analyzed the huge differences in nutrient retention and inhibitor generation among various biorefinery strategies, and emphasized that all steps in lignocellulose biorefinery need to be considered comprehensively to achieve maximum nutrient retention and optimal control of inhibitors at low cost, to provide a reference for the development of biomass energy and chemicals.
摘要：
木质纤维素的水解和生物转化,即，生物炼制,可以为人类提供生物燃料，生物基化学品，和材料,是解决化石能源危机、促进全球可持续发展的重要技术。生物炼制包括预处理等步骤，糖化,和发酵，近年来，研究人员开发了多种生物精炼策略来优化工艺并降低工艺成本。木质纤维素水解产物是连接糖化过程和下游发酵的平台。水解物组成与生物质原料密切相关,预处理过程，以及生物精炼策略的选择，不仅为下游发酵提供营养，还提供可能的抑制剂。在这次审查中,我们总结了木质纤维素生物炼制各阶段对营养物质和可能的抑制剂的影响，分析了各种生物炼制策略在营养保留和抑制剂产生方面的巨大差异，并强调木质纤维素生物炼制的所有步骤都需要综合考虑，以低成本实现最大限度的营养保留和抑制剂的最佳控制，为生物质能源和化工的发展提供参考。
