title: Roseimicrobium gellanilyticum gen. nov., sp. nov., a new member of the class Verrucomicrobiae.
abstract: The taxonomic properties of strain DC2a-G7(T), a Gram-negative, ovoid to rod-shaped, gellan gum-lysing bacterium, were examined. The 16S rRNA gene sequence similarity showed that DC2a-G7(T) is a member of the phylum Verrucomicrobia and the closest type strain of a species with a validly published name is Verrucomicrobium spinosum DSM 4136(T), with a sequence similarity of 91.2%. In addition to this similarity value lower than 95%, the absence of prostheca, the orangey-red colony colour and the compositions of the major menaquinones and polar lipids also supported the differentiation of this bacterium from the genus Verrucomicrobium. Here, we propose the name Roseimicrobium gellanilyticum gen. nov., sp. nov. for the isolate. The type strain of Roseimicrobium gellanilyticum is DC2a-G7(T) (=NBRC 108606(T)=DSM 25532(T)).
