Production of glycolate from ethylene glycol and related microbial engineering
Processes, systems and microorganisms are described herein for producing glycolate from ethylene glycol. The processes generally comprise supplying a fermentation broth into a fermentation vessel, wherein the fermentation broth comprises ethylene glycol and a microorganism having a functional metabolic pathway for utilizing ethylene glycol as a carbon source. In a growth phase, an oxygen-containing gas is injected into the fermentation broth to provide oxygen bio-availability conditions to promote cell growth of the microorganism and limit accumulation of glycolate in the fermentation broth. In a production phase, an oxygen-containing gas is injected into the fermentation broth to provide oxygen bio-availability conditions to promote production of glycolate from ethylene glycol by the microorganism and accumulation of the glycolate in the fermentation broth, to produce a glycolate enriched broth.
