Abstract
A Gram-stain-negative, milky white, aerobic, rod-shaped bacterium named strain H3-26 T was isolated from gills of Oncorhynchus mykiss in Lhasa, Tibet Autonomous Region, PR China. Strain H3-26 T grew at 4–30 °C and pH 5.0–11.0 (optimum, 25 °C and pH 7.0) with 0–1% (w/v) NaCl (optimum, 0%). The 16S rRNA gene sequence of strain H3-26 T showed the highest similarity to Deefgea rivuli WB 3.4-79 T (98.42%), followed by Deefgea chitinilytica Nsw-4 T (96.91%). Phylogenetic analysis based on 16S rRNA genes indicated that strain H3-26 T was a new member of the genus Deefgea . The digital DNA–DNA hybridization and average nucleotide identity values between the genome sequence of strain H3-26 T and Deefgea spp. were 21.2–21.9% and 76.3–77.4%, respectively. The genomic DNA G+C content of strain H3-26 T was 48.74%. The predominant fatty acids were C 12:0 , C 14:0 , C 16:0 and C 16:1 ω7c. Based on phenotypic, phylogenetic, and genotypic data, strain H3-26 T is considered to represent a novel species of the genus Deefgea , for which the name Deefgea salmonis sp. nov. is proposed. The type strain is H3-26 T (= JCM 35050 T = CICC 25103 T ).
