Abstract
With growing global attention to sustainable development and green chemistry, the issues of low efficiency, high energy consumption, and environmental pollution in the traditional conversion of chemical feedstocks urgently need to be addressed. This study focuses on biotechnology as a core approach to explore the feasibility of enhancing the conversion efficiency of chemical feedstocks by optimizing microbial me tabolic pathways and enzyme-catalyzed reactions. Specifically, representative industrial feedstocks such as lignocellulose and waste oils were selected, and gene-editing technologies and synthetic biology methods were employed to construct highly efficient engineered strains while developing a multi-stage biotransformation system compatible with these substrates. The experimental results demonstrated that the optimized engineered strains increased the yield of converting lignocellulose into high-value chemicals by 35% compared to traditional processes, with a simultaneous 20% reduction in energy consumption. In the process of converting waste oils into biodiesel, the conversion efficiency was improved by 40%, and the production of by-products was significantly reduced. Furthermore, this study innovatively introduced a dynamic regulation strategy to achieve precise control over key me tabolic nodes, thereby further enhancing the stability and economic viability of the conversion process. Overall, this research not only provides new technological pathways for the efficient conversion of chemical feedstocks but also lays a theoretical foundation for promoting the deep integration of biotechnology with the traditional chemical industry, showcasing promising application prospects and environmental benefits..Key Words：Biotechnology；Chemical Feedstock Conversion；Engineered Strain；me tabolic Pathway Optimization；Biodiesel
