Methanol-based chain elongation of acetate to i/n- butyrate by enriched microbiomes

Research output: Chapter in Book/Report/Conference proceedingAbstract

Abstract

Highlights: An enriched methanol-based chain elongation microbiome was capable of producing isobutyrate and n-butyrate at a concentration ratio that approached thermodynamic equilibrium of isomerization.
The usage of isobutyrate as electron acceptor within an enriched ethanol-based chain elongation microbiome led to isocaproate formation. Similarly isovalerate addition led to isoheptanoate formation, however at a much lower selectivity.
Carboxylates larger than acetate can be reduced to their corresponding alcohols with electrons derived from ethanol oxidation towards acetate. To drive this process the reactant to product ratios of the coupled reaction need to be sufficiently high.
