  • Publication number: 20210261993
    Abstract: Recombinant microorganisms configured for enhanced production of compounds such as 2-pyrone-4,6-dicarboxylic acid (PDC) and methods of using the recombinant microorganisms for the production of these compounds. The recombinant microorganisms include one or more modifications that reduce 2-pyrone-4,6-dicarboxylic acid (PDC) hydrolase activity, 4-carboxy-2-hydroxy-6-methoxy-6-oxohexa-2,4-dienoate (CHMOD) cis-trans isomerase activity, 4-carboxy-2-hydroxy-6-methoxy-6-oxohexa-2,4-dienoate (CHMOD) methyl esterase activity, and/or vanillate/3-O-methylgallate O-demethylase activity. The recombinant microorganisms can be used to generate PDC from media comprising plant-derived phenolics, such as syringyl phenolics, guaiacyl phenolics, and p-hydroxyphenyl phenolics. The plant-derived phenolics can be derived from pretreated lignin, including depolymerized lignin or other chemically altered lignin.

  • Publication number: 20210095265
    Abstract: Enzymes for depolymerizing lignin. The enzymes include dehydrogenases, ?-etherases, and glutathione lyases. The dehydrogenases can comprise one or more or LigD, LigO, LigN, and LigL. The ?-etherases can comprise one or more of LigE, LigF, LigP, and BaeA. The glutathione lyases can comprise any one or more of LigG and a number of non-stereospecific, optionally recombinant glutathione lyases derived from Sphingobium sp. SYK-6, Novosphingobium aromaticivorans, Escherichia coli, Streptococcus sanguinis, Phanerochaete chrysosporium, and other microorganisms. The enzymes can be combined in compositions and/or used in methods of processing lignin or other aromatic compounds in vitro.
