Data on the structures of cell wall teichoic acids, the anionic carbohydrate-containing polymers, found in many Gram-positive bacteria have been summarized and the polymers of the actinomycete genus Nocardiopsis have been considered from the taxonomic standpoint. The structures of these polymers or their combinations have been demonstrated to be indicative of each of seven Nocardiopsis species and two subspecies, verified by the DNA-DNA relatedness data, and to correlate well with the grouping of the organisms based on 16S rDNA sequences. As each of the intrageneric taxa discussed is definable by the composition of teichoic acids, the polymers are considered to be valuable taxonomic markers for the Nocardiopsis species and subspecies. The (13)C NMR spectra of the polymers, data on the products of their chemical degradation, and distinguishing constituents of whole cell walls derived from teichoic acids are discussed, which are useful for identification of certain polymers and members of the genus Nocardiopsis at the species and subspecies level in microbiological practice.
许多革兰氏阳性细菌中含有的阴离子型含糖聚合物——细胞壁磷壁酸的结构数据已被总结，并且从分类学角度对诺卡氏放线菌属的聚合物进行了研究。这些聚合物或其组合的结构已被证明可指示七种诺卡氏放线菌物种和两个亚种中的每一种，这一点已通过DNA - DNA相关性数据得到验证，并且与基于16S rDNA序列的生物分组密切相关。由于所讨论的每个属内分类单元都可通过磷壁酸的组成来定义，因此这些聚合物被认为是诺卡氏放线菌物种和亚种的有价值的分类标记。文中讨论了聚合物的(13)C NMR光谱、其化学降解产物的数据以及源自磷壁酸的全细胞壁的特征成分，这些对于在微生物学实践中在物种和亚种水平上鉴定某些聚合物和诺卡氏放线菌属成员很有用。
