The genus Cyclobacterium belongs to the phylum Bacteroidetes and includes eight species. Our study, based on the genomic parameters in silico DNA-DNA hybridization (GGDC), average nucleotide identity (OrthoANI), and average amino acid identity (AAI), confirmed that all current species of Cyclobacterium belong to this genus and constitute a coherent phylogenomic group, but with species forming two separate branches. In addition, the genome-based analyses revealed that Cyclobacterium xiamenense and Cyclobacterium halophilum are members of the same species. Besides, we carried out a taxonomic characterization of the new strain GBPx2T, isolated from the halophytic plant Salicornia sp. Analysis of its 16S rRNA gene sequence showed the highest sequence similarity (97.5%) to Cyclobacterium lianum HY9T. Percentages of GGDC and OrthoANI between strain GBPx2T and species of the genus Cyclobacterium were lower than the threshold value for species delineation. The DNA G+C content was 43.0 mol%. The polar lipids included phosphatidylethanolamine as well as one unidentified phospholipid and four unidentified lipids, and its major cellular fatty acids were iso-C15:0 and summed feature 3 (C16:1ω7c and/or iso-C15:0 2-OH). The only quinone present was menaquinone 7. Based on a combination of phenotypic, chemotaxonomic, and phylogenomic features, the GBPx2T strain represents a novel species of the genus Cyclobacterium, for which the name Cyclobacterium plantarum sp. nov. is proposed. The type strain of Cyclobacterium plantarum is GBPx2T (= IBRC-M 10634T = LMG 28551T). |
