微生物碳链延长技术转化废弃生物质合成中链脂肪酸

Under the goal of "carbon neutral", the preparation of renewable chemicals from waste biomass has become an important technology to implement major national strategies such as carbon neutrality, pollution reduction and carbon reduction. Among them, the production of medium-chain fatty acids (MCFAs) by microbial chain elongation (CE) technology is an important direction for high-value recovery of waste carbon sources. As a new star of bio-based chemicals, MCFAs have economic, environmental and practical advantages, which can partially replace fossil raw materials to synthesize environmentally friendly fuels and chemicals, reduce traditional fossil resource dependence and carbon emissions, and promote green transformation of economic and social development. This review aimed to introduce the mechanism and functional microbial communities of CE technology, as well as the key bottlenecks and research progress in the production and application of MCFAs, in order to inspire researchers to carry out innovative research and breakthrough technological bottlenecks.
