Abstract
A gram-negative, orange-pigmented, non-flagellated, gliding, rod-shaped, and aerobic bacterium, designated strain F202Z8T, was isolated from a rusty iron plate found in the intertidal region of Taean, South Korea. Notably, this strain synthesized silver nanoparticles (AgNPs), and 17 putative genes responsible for the synthesis of AgNPs were found in its genome. The complete genome sequence of strain F202Z8T is 4,723,614 bp, with 43.26% G + C content. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain F202Z8T forms a distinct lineage with closely related genera Maribacter, Pelagihabitans, Pseudozobellia, Zobellia, Pricia, and Costertonia belonging to the family Flavobacteriaceae. The 16S rRNA sequence similarity was < 94.5%. The digital DNA–DNA hybridization and average nucleotide identity values calculated from the whole genome-sequence comparison between strain F202Z8T and other members of the family Flavobacteriaceae were in the ranges of 12.7–16.9% and 70.3–74.4%, respectively. Growth was observed at 15–33°C (optimally at 30°C), at pH 6.5–7.5 (optimally at pH 7.0), and with the addition of 2.5–4.5% (w/v) NaCl to the media (optimally at 4.0%). The predominant cellular fatty acids were iso-C15: 0, iso-C15 :1 G, and iso-C17 :0 3-OH; the major respiratory quinone was MK-6. Polar lipids included phosphatidylethanolamine, five unidentified lipids, and two unidentified aminolipids. Our polyphasic taxonomic results suggested that this strain represents a novel species of a novel genus in the family Flavobacteriaceae, for which the name Aggregatimonas sangjinii gen. nov., sp. nov. is proposed. The type strain of Aggregatimonas sangjinii is F202Z8T (= KCCM 43411T = LMG 31494T).
