The invention provides non-naturally occurring microbial organisms containing enzymatic pathways and/or metabolic modifications for enhancing carbon flux through acetyl-CoA. In some embodiments, the microbial organisms having such pathways also include pathways for generating reducing equivalents, formaldehyde fixation and/or formate assimilation. The enhanced carbon flux through acetyl-CoA, in combination with pathways for generating reducing equivalents, formaldehyde fixation and/or formate assimilation can, in some embodiments, be used for production of a bioderived compound. Accordingly, in some embodiments, the microbial organisms of the invention can include a pathway capable of producing a bioderived compound of the invention. The invention still further provides a bioderived compound produced by a microbial organism of the invention, culture medium having the bioderived compound of the invention, compositions having the bioderived compound of the invention, a biobased product comprising the bioderived compound of the invention, and a process for producing a bioderived compound of the invention.
本发明提供了含有酶途径和/或代谢修饰的非天然微生物,用于通过乙酰-CoA 提高碳通量。在某些实施方案中,具有此类途径的微生物还包括产生还原当量、甲醛固定和/或甲酸同化的途径。在某些实施方案中,通过乙酰-CoA 增强的碳通量与产生还原当量、甲醛固定和/或甲酸同化的途径相结合,可用于生产生物衍生化合物。因此,在某些实施方案中,本发明的微生物有机体可以包括能够产生本发明生物衍生化合物的途径。本发明还进一步提供了一种由本发明微生物生物体生产的生物衍生化合物、具有本发明生物衍生化合物的培养基、具有本发明生物衍生化合物的组合物、包含本发明生物衍生化合物的生物基产品,以及生产本发明生物衍生化合物的工艺。
