摘要

从变质汽车轮胎的轮胎污水中分离出一株橡胶降解菌Kd2T。该菌株为需氧菌株,革兰氏阳性,产生初级分枝菌丝,菌丝破碎成棒状/球菌状元素,其化学分类标记与戈登菌的分类一致,即中二氨基戊酸、n -羟基乙酸、阿拉伯糖和半乳糖作为诊断糖,其脂肪酸模式由未分枝的饱和脂肪酸和单不饱和脂肪酸组成,并含有相当数量的结核硬脂酸。以及含有58-66个碳原子的霉菌酸,其中两种主要的霉菌酸C60和C62占60%以上。16S rDNA分析和化学分类结果表明,Gordonia sp.菌株Kd2T (= DSM 44302T)是Gordonia属内的一个新种,并建议将其命名为Gordonia polyisoprenivorans。

Gordonia polyisoprenivorans sp. nov., a rubber-degrading actinomycete isolated from an automobile tyre.

A rubber-degrading bacterium (strain Kd2T) was isolated from fouling tyre water inside a deteriorated automobile tyre. The strain was aerobic, Grampositive, produced elementary branching hyphae which fragmented into rod/coccus-like elements and showed chemotaxonomic markers which were consistent with the classification of Gordonia, i.e. meso-diaminopimelic acid, N-glycolyl muramic acid, arabinose and galactose as diagnostic sugars, a fatty acid pattern composed of unbranched saturated and monounsaturated fatty acids with a considerable amount of tuberculostearic acid, and mycolic acids comprising 58-66 carbon atoms with two principal mycolic acids C60 and C62 counting for over 60%. Results of 16S rDNA analyses as well as chemotaxonomic results, led to the conclusion that Gordonia sp. strain Kd2T (= DSM 44302T) represents a new species within the genus Gordonia for which the name Gordonia polyisoprenivorans is proposed.
