Corn, rice, wheat, and sugar are major sources of food calories consumption thus the massive agricultural waste (AW) is generated through agricultural and agro-industrial processing of these raw materials. Biological conversion is one of the most sustainable AW management technologies. The abundant supply and special structural composition of cellulose, hemicellulose, and lignin could provide great potential for waste biological conversion. Conversion of hemicellulose to xylitol, cellulose to ethanol, and utilization of remnant whole cells biomass to synthesize phenylacetylcarbinol (PAC) are strategies that are both eco-friendly and economically feasible. This co-production strategy includes essential steps: saccharification, detoxification, cultivation, and biotransformation. In this review, the implemented technologies on each unit step are described, the effectiveness, economic feasibility, technical procedures, and environmental impact are summarized, compared, and evaluated from an industrial scale viewpoint.
玉米、大米、小麦和糖是食物卡路里消耗的主要来源，因此通过这些原材料的农业和农业综合企业加工会产生大量农业废弃物（AW）。生物转化是最可持续的 AW 管理技术之一。纤维素、半纤维素和木质素的丰富供应和特殊结构组成可为废物生物转化提供巨大潜力。将半纤维素转化为木糖醇、纤维素转化为乙醇，以及利用剩余的全细胞生物质合成苯乙酮醇（PAC）是一种既环保又经济可行的策略。这种联产策略包括必要的步骤：糖化、解毒、培养和生物转化。在这篇综述中，描述了每个单元步骤所采用的技术，从工业规模的角度总结、比较和评估了从有效性、经济可行性、技术程序和环境影响等方面。
