摘要

石灰真杆菌是一种产丙酮的细菌，能够利用单碳底物——二氧化碳、一氧化碳、甲酸盐和甲醇——同时产生有价值的还原性化合物，包括丁酸盐和己酸盐。其广泛的底物范围和强大的甲醇利用率使其成为可持续甲醇生物转化的有前途的平台。遗传和分析工具的最新进展使全面的系统级表征和代谢工程成为可能。此外，甲醇混合发酵策略显著提高了能源利用率和产品产量。本文综述了羊粪草的研究进展，重点介绍了遗传工具的开发、基于甲醇的生化生产和混合营养的实施。最后，我们概述了未来的发展方向，以提高菌株的性能，并建立E. limosum作为甲醇增值的工业生物催化剂。

Eubacterium limosum as a biocatalyst for sustainable methanol bioconversion

Eubacterium limosum is an acetogenic bacterium capable of utilizing one-carbon substrates — CO₂, CO, formate, and methanol — while producing valuable reduced compounds, including butyrate and hexanoate. Its broad substrate range and robust methanol utilization make it a promising platform for sustainable methanol bioconversion. Recent advances in genetic and analytical tools have enabled comprehensive systems-level characterization and metabolic engineering. Additionally, methanol mixotrophy strategies have significantly improved energy availability and product yields. This review examines current progress in E. limosum research, focusing on genetic tool development, methanol-based biochemical production, and mixotrophy implementation. We conclude by outlining future directions for enhancing strain performance and establishing E. limosum as an industrial biocatalyst for methanol valorization.
