摘要:

维生素B12是人体、动物及多种微生物必需的小分子化合物,广泛参与一碳代谢、同型半胱氨酸的甲基化及脂肪酸代谢等生理过程。近年来,随着微生物学与代谢工程的快速发展,微生物发酵法合成维生素B12的研究取得了显著进展。本文首先简要介绍了维生素B12合成途径,然后回顾了近十年几种主要合成维生素B12的微生物,包括工业生产菌株PseudomonasdenitrificansSinorhizobium melilotiEnsifer adhaerensPropionibacterium freudenreichii和近几年新出现的人工菌种异源合成维生素B12方面的研究进展,探讨了这些微生物的代谢工程策略、发酵工艺以及在工业化生产中的应用潜力。此外,还分析了当前研究的挑战与未来发展方向,如基因工程改造与代谢调控策略在提高维生素B12生产中的应用。通过对这些微生物的合成途径的深入了解,有望为工业规模维生素B12生产提供新的理论依据和技术支持。

Abstract:

Vitamin B12 is an essential small molecule compound for humans, animals and many microorganisms, which is widely involved in physiological processes such as one-carbon metabolism, homocysteine methylation and fatty acid metabolism. In recent years, with the development of microbiology and metabolic engineering, the research on microbial fermentation synthesis of vitamin B12 has made remarkable progress. In this paper, we first briefly introduce the vitamin B12 synthesis pathway, and then review several major microorganisms synthesizing vitamin B12 in the last decade, including the industrial production strain Pseudomonas denitrificans, Sinorhizobium meliloti, Ensifer adhaerens, and Propionibacterium freudenreichii, and newly emerged artificial strains in recent years for heterologous synthesis of vitamin B12. The article discusses the metabolic engineering strategies, fermentation processes and the potential application of these microorganisms in industrial production. In addition, current research challenges and future directions are analyzed, such as the application of genetic engineering modifications and metabolic regulation strategies in enhancing vitamin B12 production. The in-depth understanding of the synthetic pathways of these microorganisms is expected to provide new theoretical basis and technical support for industrial-scale vitamin B12 production.
