Methanol-based chain elongation for isomerised fatty acids production from supermarket food waste
Isobutyrate is an emerging platform chemical that is currently produced from fossil-based feedstocks.This study reported for the first time an isobutyrate biosynthesis through a novel bioprocess,i.e.methanol chain elongation,that uses an undefined mixed culture microbiome as the catalyst and organic residues as the feedstock.Isobutyrate production (6.2 g/L) using a real waste feedstock,i.e.acidified supermarket waste (ASW),via methanol chain elongation was demonstrated in a batch test.Besides isobutyrate production,a simultaneous valerate (2.4 g/L),isovalerate (0.5 g/L) and caproate (0.8 g/L) formation was observed in this batch test.The reported isobutyrate biosynthesis through methanol chain elongation is potentially more sustainable than the current isobutyrate production processes due to the use of a renewable organic residues as feedstocks and a self-regenerating,non-hazardous biocatalyst.The concurrent formation of value-added organic acids,e.g.valerate,isovalerate and caproate,further valorises the organic residues and promotes the potential of methanol chain elongation.
