Abstract

A Gram-positive bacterium which was isolated from a Finnish soil and identified as a Nocardia sp., was able to decompose lignin and to assimilate lignin degradation products as a carbon source. It could release 14CO2 from 14C-labelled methoxyl groups, side chains or ring carbons of coniferyl alcohol dehydropolymers (DHP) and from specifically 14C-labelled lignin of plant material. Furthermore, it could release 14CO2 from phenolcarboxylic and cinnamic acids and alcohols labelled in the OCH3, COOH groups, side chain or aromatic ring carbons.

摘要

从芬兰土壤中分离出的一株革兰氏阳性菌,经鉴定为诺卡氏菌属,它能够分解木质素,并将木质素降解产物作为碳源进行同化。它可以从松柏醇脱氢聚合物(DHP)的14C标记的甲氧基、侧链或环碳以及植物材料中特定的14C标记的木质素中释放出14CO2。此外,它还可以从在OCH3、COOH基团、侧链或芳环碳上标记的酚羧酸、肉桂酸和醇中释放出14CO2。
