A novel alphaproteobacterium, strain LD81(T), was isolated from the marine macroalga. Laminaria saccharina. The bacterium is mesophilic and shows a typical marine growth response. It is a chemoheterotrophic aerobe with the potential for denitrification. Growth optima are 25 degrees C, pH 5.5 and 3% NaCl. Strain LD81(T) has a unique phylogenetic position, not fitting any of the known families of the Alphaproteobacteria. The 16S rRNA gene sequence revealed a distant relationship to species of several orders of the Alphaproteobacteria, with less than 90% sequence similarity. Phylogenetically, strain LD81(T) is related to the type strains of Terasakiella pusilla (88.4% 16S rRNA gene sequence similarity) and the three Thalassospira species (88.9-89.2%. It forms a cluster with these bacteria and a novel as-yet undescribed isolate (KOPRI 13522; 96.6% sequence similarity). Strain LD81(T) has a relatively low DNA G + C content (51.1 mol%) and, due to its distant phylogenetic position from all other alphaprotecibacteria, strain LD81(T) (=NCIMB 14374(T) =JCM 14845(T)) is considered as the type strain of a novel species within a new genus, for which the name Kiloniella laminariae gen. nov., sp. nov. is proposed. The genus Kiloniella represents the type of the new family Kiloniellaceae fam. nov. and order Kiloniellales ord. nov.
