测定了3株Oscillochloris trichoides类型菌株DG-GT和3株Oscillochloris样中温丝状绿菌新菌株的16S rrna基因序列。通过系统发育分析，在绿草科中发现了两个主要的类群：一个类群包括嗜热的绿草属，另一个类群包括嗜温的绿草属。这些聚类的亲缘程度低于属间水平，16S rDNA序列相似性仅为82.5 ~ 86.5%。这些系统发育数据与显著的生理变化密切相关。两组成员之间的生化和化学分类学差异。因此，Oscillochloris和Chloroflexus应被视为两个独立的科。新科示波器氯科的描述。11月11日，提出了Oscillochloris属和Oscillochloris trichoides种的订正描述。
The nucleotide sequences of the genes of 16S rRNAs were determined for the type strain Oscillochloris trichoides DG-GT and three new strains of Oscillochloris-like mesophilic filamentous green bacteria. Two major clusters have been found within the family Chloroflexaceae by phylogenetic analysis: one cluster includes thermophilic species of Chloroflexus and the second includes mesophilic strains of Oscillochloris. The degree of relatedness of these clusters was below an intergeneric level, having only 82.5-86.5 % of 16S rDNA sequence similarity. These phylogenetic data correlate well with the significant physiological. biochemical and chemotaxonomical differences between members of both groups. Therefore, the Oscillochloris and Chloroflexus clusters should be considered as two separate families. The description of the new family, Oscillochloridaceae fam. nov., and emended descriptions of the genus Oscillochloris and the species Oscillochloris trichoides are presented.
