Abstract:

Synthetic biology, as a discipline that designs, constructs, and modifies biological systems to achieve specific functions, is widely applied in fields such as biomanufacturing, environmental protection, and drug synthesis. Systematic exploration of gene functions and the construction of engineered strain libraries are key drivers of the development of synthetic biology. These libraries serve as foundational tools for understanding complex biological processes and engineering microorganisms for novel applications. This review focuses on the construction methods and application prospects of various yeast libraries in synthetic biology. With the rapid advancement of genome sequencing and high-throughput technologies, microbial libraries, such as those of Saccharomyces cerevisiae and Schizosaccharomyces pombe, play a pivotal role in systematic research. Yeast libraries, including gene knockout libraries, overexpression libraries, and transposon insertion libraries, provide valuable tools for optimizing gene combinations and designing metabolic pathways, thus promoting innovative applications in metabolic engineering and synthetic biology. These libraries facilitate the development of high-yield industrial strains, driving improvements in biofuel production, chemical synthesis, and other biotechnological processes. In the environmental field, gene modification screening generates strains with pollutant degradation capabilities, contributing to ecological restoration. In drug synthesis, these libraries aid in constructing strains for the efficient production of pharmaceutical compounds, advancing the development of biopharmaceuticals. Despite these successes, there remain several challenges in library construction and application, such as the high costs of library generation, difficulties in precise genome editing, and limitations in screening efficiency. In the future, advances in automation, digitization, and novel screening technologies are expected to overcome these limitations, facilitating the rapid construction and efficient screening of yeast libraries. Looking ahead, the future of synthetic biology holds immense promise, with improvements in library construction and screening processes expected to accelerate the development of sustainable solutions in industrial production, environmental protection, and healthcare, thereby driving the next wave of innovations in biotechnology.

摘要:

合成生物学作为一门通过设计、构建和改造生物系统来实现其特定功能的学科,被广泛应用于生物制造、环境保护和药物合成等领域。基因功能的系统性探索和工程菌株文库的构建是推动合成生物学发展的重要手段。本研究重点介绍了不同酵母文库在合成生物学中的构建方法及其应用前景。随着基因组测序和高通量技术的快速进展,酿酒酵母和裂殖酵母等微生物文库在系统性研究中发挥了关键作用。基因缺失文库、过表达文库、转座子插入文库等多种类型的酵母文库为基因组合优化和代谢路径设计提供了重要工具,促进了代谢工程和合成生物学的创新应用。这些文库在工业生产中支持高产菌株的构建,如用于生物燃料和化学品的高效生产;在环境领域,通过基因改造筛选,生成具备污染物降解能力的菌株,为生态修复提供解决方案;在药物合成方面,文库帮助构建高效合成药用化合物的菌株,推动生物制药的发展。然而,当前文库构建和应用仍面临诸如构建成本、基因组编辑的精确度及筛选效率等技术瓶颈。未来,自动化、数字化和新型筛选技术的进步有望突破这些瓶颈,推动酵母文库的快速构建和高效筛选,从而加速合成生物学在可持续发展和生态工程中的应用。
