Four strains of nonmotile, prosthecate bacteria were isolated in the 1970s and assigned to the genus Prosthecobacter. These strains were compared genotypically by DNA/DNA reassociation and 16S rDNA based phylogenetic analyses. Genotypic comparisons were complemented with phenotypic characterizations. Together, these studies clearly indicate each Prosthecobacter strain represents a novel species of bacteria. We propose three new species of Prosthecobacter, P. dejongeii strain FC1, P. vanneervenii strain FC2, and P. debontii strain FC3; P. fusiformis is reserved for the type strain of the genus, strain FC4. Additionally, we propose the genera Prosthecobacter and Verrucomicrobium, currently members of the order Verrucomicrobiales, to comprise a novel higher order taxonomic group, the division Verrucomicrobia div. nov. and the class Verrumicrobiae class nov. Many novel members of the Verrucomicrobia, as revealed by molecular ecology studies, await isolation and description.
20世纪70年代分离出了四株无运动性、具柄细菌，并将其归入柄杆菌属。通过DNA/DNA重联和基于16S rDNA的系统发育分析对这些菌株进行了基因型比较。基因型比较辅以表型特征分析。这些研究共同明确表明，每一株柄杆菌都代表一种新的细菌物种。我们提出柄杆菌属的三个新物种，即德容氏柄杆菌FC1菌株、范内尔芬氏柄杆菌FC2菌株和德邦氏柄杆菌FC3菌株；梭形柄杆菌保留给该属的模式菌株FC4菌株。此外，我们提议目前属于疣微菌目的柄杆菌属和疣微菌属组成一个新的高级分类群，即疣微菌门新分类单元和疣微菌纲新分类单元。分子生态学研究揭示，疣微菌门的许多新成员有待分离和描述。
