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.
本公开的一个方面是一种微生物细胞,它包括导致表达内源二氧 化酶缺陷形式的遗传修饰,以及编码外源二氧 化酶的基因和启动子序列,其中内源二氧 化酶包括 PcaH 和 PcaG、外源二氧化酶包括 LigA 和 LigB,微生物细胞能够利用纤维素分解分子或木质素分解分子中的至少一种进行生长,微生物细胞能够产生 2-羟基-2H-吡喃-4,6-二羧酸。
