在土壤细菌(Pseudomonas paucimobilisSYK-6)中，DDVA(木质素的联苯结构)和丁香酸(阔叶木木质素中特有的芳香环)的代谢是通过共同的中间体3-甲基没食子酸进行的。原儿茶酸盐也是香草酸和对羟基苯甲酸代谢的中间产物。3-甲基没食子酸和原儿茶酸是微生物降解木质素的最终芳香中间体，是原儿茶酸-4，5-双加氧酶的底物，原儿茶酸-4，5-双加氧酶是该细菌从木质素的各种结构中获得代谢能量的关键酶。
In the soil bacterium (Pseudomonas paucimobilisSYK‐6), the metabolism of DDVA (biphenyl structure of lignin) and syringic acid (characteristic aromatic ring in hardwood lignin) proceeds via a common intermediate, 3‐methylgallic acid. Protocatechuate is also an intermediate in the metabolism of vanillate andp‐hydroxybenzoic acid. 3‐Methylgallic acid and protocatechuate are the final aromatic intermediates in lignin microbial degradation and these compounds are substrates of protocatechuate‐4,5‐dioxygenase, which is a key enzyme in obtaining metabolic energy from various structures of lignin in this bacterium.
