DESCRIPTION OF NOCARDIOPSIS-SYNNEMATAFORMANS SP. NOV., ELEVATION OF NOCARDIOPSIS-ALBA SUBSP PRASINA TO NOCARDIOPSIS-PRASINA COMB. NOV., ANDDESIGNATION OF NOCARDIOPSIS-ANTARCTICA AND NOCARDIOPSIS-ALBORUBIDA ASLATER SUBJECTIVE SYNONYMS OF NOCARDIOPSIS-DASSONVILLEI

Data from chemotaxonomic and 16S ribosomal DNA sequence analyses of an isolate obtained from the sputum of a kidney transplant patient ident ified the isolate as a member of the genus Nocardiopsis. DNA-DNA hybri dization data, as well as physiological characteristics, indicated tha t the isolate represents a new species of the genus Nocardiopsis, desi gnated Nocardiopsis synnemataformans; the type strain is strain IMMIB D-1215 (= DSM 44143), In addition, DNA-DNA hybridization data, as well as the results of biochemical tests, indicated that Nocardiopsis albo rubida DSM 40465(T), Nocardiopsis antarctica DSM 43884(T), and Nocardi opsis dassonvillei DSM 43111(T) represent a single species designated N. dassonvillei, We also found that Nocardiopsis alba subsp. alba DSM 43377(T) and N. alba subsp, prasina DSM 43845(T) are genetically diffe rent and therefore propose that N. alba subsp. prasina be elevated to species status as Nocardiopsis prasina comb. nov., whose type strain i s strain DSM 43845.
