These organisms are members of the α-4 subclass of the Proteobacteria. Strain T4T is a motile, red or orange bacterium. The major carotenoids are bacteriorubixanthinal and erythroxanthin sulfate. In vivo measurements revealed bacteriochlorophyll absorption maxima at 377, 590, 800, and 868 nm. Strain T4T grows in the presence of 5 to 96%o basis of its distinct phylogenetic position and phenotypic characteristics which are different from those of Erythrobacter longus, we propose that strain T4T should be placed in a new species of the genus Erythrobacter, Erythrobacter litoralis. The descriptions of ““Roseococcus thiosulfatophilus” and ““ Erythromicrobium ramosum” are emended. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-44-3-427
