Abstract

Members of the species were isolated from marine environments. The type strain of this species (=LMG 22047=ATCC 25652) was recently reclassified in the new genus , in the order ‘’ of the class ‘’. Strain LMG 128 (=ATCC 25654) was also initially classified as belonging to the species ; however, the nearly complete 16S rRNA gene sequence of this strain indicated that it does not belong within the genus or within the genus . The closest related organism, with 95·5 % 16S rRNA gene similarity, was from the family ‘’ in the order ‘’. The remaining genera from this order had 16S rRNA gene sequence similarities that were lower than 95·1 % with respect to strain LMG 128. These phylogenetic distances suggested that strain LMG 128 belonged to a different genus. The major fatty acid present in strain LMG 128 was mono-unsaturated straight chain 18 : 17. The G+C content of the DNA was 53·1 mol%. Strain LMG 128 grew at 4 °C but not at 40 °C, and tolerated up to 5 % NaCl. The pH range for growth was 6–8. It produced urease and -galactosidase, and hydrolysed aesculin. Denitrification was negative. Growth was observed with many carbohydrates as the only carbon source. The data from this polyphasic study indicate that this strain belongs to a new genus of the family ‘’, and therefore it is proposed that strain LMG 128 should be reclassified as representing a novel species within the new genus gen. nov., for which the name sp. nov. is proposed.
