Abstract

Previously we proposed the reclassification of a thermotolerant phototrophic bacterium, ‘’ Stadtwald-Demchick 1990, as ‘’ nom. rev., comb. nov. with strain DSM 9987 (ATCC 49414) as the type strain. However, while both the names ‘’ and ‘’ have not been validated, strain ATCC 49414 is no longer available from the culture collection. This situation indicates that the taxonomic status of the bacterium with both the names to be validated has been lost. In this study, we re-examined the taxonomic characteristics of strain DSM 9987 (TUT3520 as our own collection number) compared with those of six species of the genus with validly published names. The results of 16S rRNA gene sequence comparisons indicated that TUT3520 had a 99.0 % level of similarity to the type strains of and as its closest relatives and 98.9–96.2 % similarities to other species of the genus . Genomic DNA–DNA similarities between TUT3520 and the type strains of the species of the genus were less than 50 %. Results of phenotypic testing indicated that TUT3520 could be differentiated from any species of the genus by a combination of absorption spectra, growth temperature, vitamin requirements, carbon nutrition and some other characteristics. Thus, we propose sp. nov. to accommodate the bacterium previously referred to as ‘ () ’. The type strain is strain TUT3520 (=DSM 9987=NBRC 104267).
