A novel thermophilic bacterium, strain K14T, capable of degrading poly(3-hydroxybutyrate) as well as copolymers containing 3-hydroxybutyrate and 3-mercaptopropionate linked by thioester bonds, was isolated. 16S rDNA sequence analysis showed that strain DhA-71, a dehydroabietic acid-degrading bacterium, was the nearest phylogenetic neighbour and that both strains should be placed as members of a newly created genus, Schlegelella gen. nov., in the Rubrivivax subgroup of the beta-Proteobacteria. Strain K14T (= LMG 21644T = DSM 15344T) is proposed as the type strain of Schlegelella thermodepolymerans gen. nov., sp. nov. Its phylogenetic, morphological, biochemical and chemotaxonomic characteristics are described in detail.
分离出了一种新型嗜热细菌K14T菌株，它能够降解聚（3-羟基丁酸酯）以及含有通过硫酯键连接的3-羟基丁酸酯和3-巯基丙酸酯的共聚物。16S rDNA序列分析表明，脱氢枞酸降解菌DhA-71菌株是其最近的系统发育邻居，这两个菌株都应归为新创建的Schlegelella属（属名）的成员，属于β-变形菌纲红环菌亚群。提议将K14T菌株（= LMG 21644T = DSM 15344T）作为热解聚Schlegelella属（属名）、新种的模式菌株。详细描述了其系统发育、形态、生化和化学分类学特征。
