Neighbor-joining analysis of the 16S rRNA gene showing the evolutionary distance of Halomonas sp. R57-5 to a selection of Halomonas species: H. titanicae (BH1) (NR_117300.1), H. boliviensis (LC1) (NR_029080.1), H. variabilis (DSM 3051) (NR_042068.1), H. zhanjiangensis (JSM 078169) (NR_104283.1), H. gomseomensis (M12) (NR_042488.1), H. halodurans (ATCC BAA-125) (HQ449183.1), H. stevensii (S18214) (NR_115088.1), H. alkaliphila (18bAG) (NR_042256.1), H. venusta (DSM 4743) (NR_118033.1), H. campaniensis (ATTCC BAA-96) (AJ515365.2), H. salina (F8-11) (AJ295145.1) and H. maura (S-31) (NR_042010.1). Bootstrap values greater than 50 % based on 1000 repetitions are shown with Cobetia marina (NR_042065.1) used as an outgroup. The tree was produced using the Ribosomal Database Project (RDP) ‘Tree builder’ tool [45]: The scale bar on the tree represents the percentage sequence dissimilarity between two sequences
