Abstract

The present disclosure relates to a method for recovering a vinyl acid monomer by providing an aqueous fermentation broth which undergoes microbial fermentation of a nutrient medium containing a carbon source including at least one microorganism to produce a vinyl acid monomer. The method provides a direct overall route to bio-based polymers of the vinyl acid monomer, and in particular, polymers of polyitaconic acid.
