processes for producing methacrylic acid, fermentation medium, microorganism, recombinant microorganism, bioreactor, method for preparing polymers or copolymers of methacrylic acid or esters of methacrylic acid, and, polymethacrylic acid, polymethyl methacrylate and polybutyl methacrylate homopolymers or copolymers

摘要

The invention relates to a process of producing methacrylic acid and / or derivatives thereof comprising the following steps: (a) biologically converting isobutyryl coa to methacrylyl coa by the action of an oxidase; and (b) converting methacrylylco to methacrylic acid and / or derivatives thereof. The invention also extends to microorganisms adapted to conduct the process steps.
