Ferrimonas gelatinilytica sp. nov., isolated from tidal flat sediment

Abstract

A novel beige-pigmented, Gram-staining-negative, coccoid, motile and facultatively anaerobic bacteria, designated strain CJ24T, was isolated from the tidal flat sediment of the Yellow Sea in South Korea. Characterization of this strain was performed on the basis of polyphasic taxonomic methods. Phylogenetic analysis of the 16S rRNA and gyrB genes revealed that strain CJ24T belongs to the genus Ferrimonas , sharing the highest 16S rRNA gene sequence similarity of 96.9 % with Ferrimonas marina DSM 16917T. Strain CJ24T was able to grow optimally at 30 °C, at pH 6.0 and in the presence of 2 % NaCl (w/v). As an isoprenoid quinone, menaquinone (MK-7) was predominantly identified from this strain, while ubiquinone (Q-7) was also present as a minor component. The DNA G+C content of strain CJ24T was 60.2 mol%. The most abundant cellular fatty acids were C15 : 0 iso, C18 : 1ω9c, C16 : 0 and C17 : 0 iso. Therefore, strain CJ24T represents a novel species in the genus Ferrimonas for which the name Ferrimonas gelatinilytica sp. nov. is proposed; the type strain is CJ24T ( = KACC 17065T = JCM 18720T).
