Title: Conversion of biomass to useful intermediates

Abstract

An aspect of the present disclosure is a microbial cell that includes a genetic modification resulting in the expression of a deficient form of an endogenous dioxygenase, and a gene encoding an exogenous dioxygenase and a promoter sequence, where the endogenous dioxygenase includes PcaH and PcaG, the exogenous dioxygenase includes LigA and LigB, the microbial cell is capable of growth utilizing at least one of a cellulose decomposition molecule or a lignin decomposition molecule, and the microbial cell is capable of producing 2-hydroxy-2H-pyran-4,6-dicarboxylic acid.
