Two Gram-negative, vibrioid, phototrophic, purple non-sulfur strains, JA131T and JA135T, were isolated from marine habitats. Strain JA131T is non-motile but strain JA135T is motile by means of a pair of monopolar flagella. Both strains have an obligate requirement for NaCl for growth. The intracellular photosynthetic membranes of the two novel strains are of the vesicular type. Bacteriochlorophyll a and probably rhodovibrine are present as photosynthetic pigments. Niacin, thiamine and p-aminobenzoic acid are required as growth factors for both novel strains. Based on 16S rRNA gene sequence analysis, morphological and physiological characteristics, strains JA131T and JA135T are significantly different from each other and from other species of the genus Roseospira and thus represent two novel species for which the names Roseospira visakhapatnamensis sp. nov. and Roseospira goensis sp. nov. are proposed, respectively. The type strain of Roseospira visakhapatnamensis sp. nov. is JA131T (=ATCC BAA-1365T=JCM 14190T) and the type strain of Roseospira goensis sp. nov. is JA135T (=ATCC BAA-1364T=JCM 14191T).

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains JA131T and JA135T are AM282560 and AM283537, respectively.

Phase contrast images and transmission electron micrographs of cells of strains JA131T and JA135T and plots of the absorption spectra of extracted pigments from the two strains are available with the online version of this paper.
