Nocardia flavorosea sp. nov.
An actinomycete strain, 'Nocardai flavorosea' JCM 3332, was found to have properties consistent with its classification in the genus Nocardia. An almost complete gene sequence of the 16S rDNA of the strain was determined following cloning and sequencing of the amplified gene. The sequence was aligned with those available for nocardiae and phylogenetic trees were inferred using four tree-making algorithms. The organisms consistently formed a distinct clade with the type strain of Nocardia carnea. However, DNA relatedness experiments showed that the strain and N. carnea DSM 43397T belonged to two distinct genomic species. The organism was also distinguished from representative of all of the validly described species of Nocardia using a combination of phenotypic properties. These genotypic and phenotypic data show that the strain merits recognition as a new species of the genus Nocardia. The name proposed for the new species of is Nocardia flavorosea sp. nov. The type strain is JCM 3332T.
