Abstract

A Gram-stain-positive, rod-shaped and motile strain, designated FJAT-49705, was isolated from the citrus rhizosphere soil sample. Strain FJAT-49705 grew at 20–40 °C (optimum, 30 °C) and pH 6.0–11.0 (optimum, pH 7.0) with 0–5 % (w/v) NaCl (optimum, 2 %). Strain FJAT-49705 showed high 16S rRNA gene sequence similarity to ‘’ FJAT-25496 (99.7 %) and FJAT-18043 (98.0 %). In phylogenetic (based on 16S rRNA gene sequences) and phylogenomic trees (based on 71 bacterial single-copy genes), strain FJAT-49705 clustered with the members of the genus . MK-7 was the only isoprenoid quinone present. The main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The major fatty acids were anteiso-C and iso-C. The genomic DNA G+C content was 36.9 %. The average nucleotide identity (ANI) values between FJAT-49705 and ‘’ FJAT-25496 and FJAT-18043 were below the cut-off level (95–96 %) recommended as the ANI criterion for interspecies identity. Based on the above results, strain FJAT-49705 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is FJAT-49705 (=CCTCC AB 2019243= LMG 31580).
