  • Patent number: 9476073
    Abstract: The invention concerns a microorganism which is genetically modified so as to i) synthesize an organic monomer by fermentation of a carbon source, and ii) depolymerize a polymer constituted at least by an organic monomer which it is capable of synthesizing. The invention also concerns a method for producing an organic monomer using a genetically modified microorganism of this type, as well as the coculture of this microorganism with another microorganism which is capable of synthesizing a polymer of interest.
