从劣化汽车轮胎内污损的轮胎水中分离到一株橡胶降解菌Kd2(T)。该菌株是一株革兰氏阳性菌，能产生基本的分枝菌丝，菌丝碎裂成杆状或球状分子，并显示出与Gordonia分类一致的化学标记，即Meso-二氨基甲酸、N-羟基壁酸、阿拉伯糖和半乳糖为诊断糖，脂肪酸模式由不支化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，真菌酸由58-66个碳原子组成，两种主要的真菌酸C-60和C-62占60%以上。16S rDNA分析结果与化学分类学结果相结合，得出了Gordia sp.菌株Kd2(T)(=Dsm 44302(T))是高丹属的一个新种，建议将其命名为多异丙二烯食用菌。
A rubber-degrading bacterium (strain Kd2(T)) 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 C-60 and C-62 counting for over 60%. Results of 16S rDNA analyses as well as chemotaxonomic results, led to the conclusion that Gordonia sp. strain Kd2(T) (= DSM 44302(T)) represents a new species within the genus Gordonia for which the name Gordonia polyisoprenivorans is proposed.
