目前的生物炼制方法包括各种生物质原料和各种转化技术，以生产各种高价值的生物化学品和生物燃料。木质纤维素是地球上最丰富、生物可再生和可持续的生物资源之一。它被认为是生产大量化学品和生物燃料的巨大替代原料。从木质纤维素生物质生产生物燃料和平台化学品在能源和环境方面具有优势。木质纤维素是非木本和木本植物的主要结构成分，由木质素、纤维素和半纤维素组成。所有这些组分的有效利用可能对工艺的经济可行性起到相当大的贡献，因为木质纤维素生物质通常需要预处理以释放可发酵糖和附加值产品，所述附加值产品可能用作微生物菌株的原料以生产生物燃料和生物化学品。开发强大的微生物培养和代谢工程方法的进步可能会导致快速构建细胞工厂，以有效地对生物质原料进行生物技术转化，从而生产生物炼制产品。在这个全面的审查中，我们讨论了最近的进展，在增值的农业工业废物作为有前景的微生物原料，以产生一系列高价值的产品，如微生物色素，生物聚合物，工业生物催化剂，生物燃料，生物活性化合物，生物塑料，生物表面活性剂和生物控制剂与治疗和工业潜力。木质纤维素生物质的结构，组成方面，revalorization，和预处理策略概述了木质纤维素生物质的有效转化。此外，代谢工程方法简要强调发展细胞工厂，使木质纤维素生物炼制平台的吸引力。
Current biorefinery approaches comprehend diverse biomass feedstocks and various conversion techniques to produce a variety of high-value biochemicals and biofuels. Lignocellulose is among the most abundant, bio-renewable, and sustainable bioresources on earth. It is regarded as a prodigious alternative raw feedstock to produce a large number of chemicals and biofuels. Producing biofuels and platform chemicals from lignocellulosic biomasses represent advantages in terms of energy and environmental perspectives. Lignocellulose is a main structural constituent of non-woody and woody plants consisting of lignin, cellulose, and hemicellulose. Efficient exploitation of all these components is likely to play a considerable contribution to the economic viability of the processes since lignocellulosic biomass often necessitate pretreatment for liberating fermentable sugars and added value products that might serve as feedstocks for microbial strains to produce biofuels and biochemicals. Developing robust microbial culture and advancements in metabolic engineering approaches might lead to the rapid construction of cell factories for the effective biotechnological transformation of biomass feedstocks to produce biorefinery products. In this comprehensive review, we discuss the recent progress in the valorization of agro-industrial wastes as prospective microbial feedstocks to produce a spectrum of high-value products, such as microbial pigments, biopolymers, industrial biocatalysts, biofuels, biologically active compounds, bioplastics, biosurfactants, and biocontrol agents with therapeutic and industrial potentialities. Lignocellulosic biomass architecture, compositional aspects, revalorization, and pretreatment strategies are outlined for efficient conversion of lignocellulosic biomass. Moreover, metabolic engineering approaches are briefly highlighted to develop cell factories to make the lignocellulose biorefinery platforms appealing.
