A bacterial isolate identified as Xanthomonas sp. proved to be ligninolytic due to its ability to degrade 14C-labeled dehydropolymers of coniferyl alcohol (DHP) and [14C]lignocellulose complexes from corn plants (Zea mays). Several parameters of ligninolysis were evaluated and it was shown that resting cells degrade DHP as sole carbon source. Enhancement of DHP degradation in the presence of ferulic acid or water-soluble fractions of DHP or of dioxane lignin from wheat was demonstrated. It is shown that a dissociation of DHP takes place during incubation in the absence of the bacteria which is reflected in a shift of DHP to lower molecular weight fractions. Bacterial degradation of [14C]DHP results in the release of 14CO2 and in the incorporation of the 14C-label into the biomass of the bacteria, as shown by chemical and biological methods.
一种被鉴定为黄单胞菌属的细菌分离物，因其能够降解来自玉米植株（玉米）的14C标记的松柏醇脱氢聚合物（DHP）和[14C]木质纤维素复合物，而被证明具有木质素分解能力。评估了木质素分解的几个参数，结果表明静止细胞能够将DHP作为唯一碳源进行降解。结果表明，在阿魏酸、DHP的水溶性组分或小麦二氧六环木质素存在的情况下，DHP的降解得到增强。结果表明，在没有细菌的情况下孵育期间，DHP会发生解离，这反映在DHP向较低分子量组分的转变上。化学和生物学方法表明，细菌对[14C]DHP的降解会导致14CO2的释放，并使14C标记掺入细菌的生物量中。
