Expression of biocatalysts and their use in monomer synthesis for biodegradable polymers from acetone and CO2

One-pot β-hydroxybutyrate synthesis from CO 2 and acetone in an aqueous solution with acetone carboxylase and β-hydroxybutyrate dehydrogenase extracted from Rhodobacter capsulatus SB1003 by culturing in an acetone–bicarbonate medium was developed.
