摘要
Identified as a newly described species from a biocrust in Svalbard, Norway (78° 54′ 8.27″ N 12° 01′ 20.34″ E), isolate PAP01 T has different characteristics from any known predatory bacteria. The isolate was vibrio-shaped strain that employed flagellar motility. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate clustered within the genus Bdellovibrio in the family Bdellovibrionaceae . 16S rRNA gene sequence similarities between strain PAP01 T and the type strain ( Bdellovibrio bacteriovorus HD100) was 95.7 %. The PAP01 T genome has a size of 3.898 Mbp and possesses 3732 genes and a G+C content of 45.7 mol%. The results of genetic and physiological tests indicated the phenotypic differentiation of strain PAP01 T from the two other Bdellovibrio species with validly published names. Based on the physiological and phylogenetic data, as well as the prey range spectrum and osmolality sensitivities, isolate PAP01 T represents a novel species within the genus Bdellovibrio , for which the name Bdellovibrio svalbardensis sp. nov. is proposed. The type strain is PAP01 T (=KCTC 92583 T =DSM 115080 T ).
