摘要
生物转化作为一种绿色高效的有机废物资源化技术，近年来受到广泛关注。随着全球有机废物排放量的持续增加，传统处理方式面临效率低、能耗高及二次污染等问题，而生物转化技术凭借其环境友好性和经济可行性为有机废物的高效利用提供了新途径。本研究旨在探讨微生物代谢、酶催化和植物修复等生物转化机制在有机废物资源化中的应用潜力，并通过实验设计与数据分析评估其技术可行性和经济性。研究采用实验室规模的反应器模拟不同类型的有机废物处理过程，结合宏基因组学和代谢组学技术揭示关键微生物群落及其功能特性。结果表明，特定功能微生物能够显著提高有机废物中目标化合物的转化效率，同时降低处理成本和环境风险。此外，研究还发现优化工艺参数（如温度、pH值和碳氮比）可进一步提升系统性能。然而，生物转化技术在实际应用中仍面临诸多挑战，包括复杂废弃物成分导致的微生物适应性问题以及规模化生产的技术瓶颈。本研究的创新点在于首次提出基于功能微生物群落定向调控的优化策略，并建立了适用于多种有机废物的通用转化模型，为推动生物转化技术的工业化应用奠定了理论基础。研究成果不仅拓展了有机废物资源化的技术路径，也为可持续发展提供了重要参考。

Abstract
Biological transformation, as a green and highly efficient technology for the resource recovery of organic waste, has garnered significant attention in recent years. With the continuous increase in global organic waste emissions, traditional treatment methods are confronted with challenges such as low efficiency, high energy consumption, and secondary pollution. In contrast, biological transformation technologies offer new avenues for the effective utilization of organic waste due to their environmental friendliness and economic feasibility. This study investigates the application potential of biological transformation mechanisms, including microbial me tabolism, enzyme catalysis, and phytoremediation, in the resource recovery of organic waste. Through experimental design and data analysis, the technical feasibility and economic viability of these mechanisms are evaluated. Laboratory-scale reactors were employed to simulate the treatment processes of various types of organic waste, while me tagenomics and me tabolomics techniques were integrated to reveal key microbial communities and their functional characteristics. The results indicate that specific functional microorganisms can significantly enhance the conversion efficiency of target compounds in organic waste while reducing treatment costs and environmental risks. Furthermore, it was found that optimizing process parameters, such as temperature, pH, and carbon-to-nitrogen ratio, could further improve system performance. However, the practical application of biological transformation technologies still faces numerous challenges, including microbial adaptability issues caused by complex waste compositions and technical bottlenecks in scaled-up production. The innovation of this study lies in the first proposal of an optimization strategy based on targeted regulation of functional microbial communities, along with the establishment of a universal transformation model applicable to various types of organic waste. This lays a theoretical foundation for promoting the industrial application of biological transformation technologies. The research findings not only expand the technical pathways for the resource recovery of organic waste but also provide important references for sustainable development.
