Devosia salina sp. nov., isolated from South China Sea sediment

Abstract

An aerobic, Gram-stain-negative, rod-shaped and motile strain, designated SCS-3T, was isolated from deep-sea sediment of the South China Sea. Phylogenetic analysis based on the 16S rRNA gene sequence similarities revealed that strain SCS-3T represented a novel species of the genus Devosia , with closely related strains ' Devosia sediminis ' MSA67T (98.61 %), Devosia riboflavina IFO13584T (98.22 %) and Devosia indica IO390501T (97.72 %). The G+C content of the genomic DNA is 63.44 mol%. The digital DNA–DNA hybridization values with ' D. sediminis ' MSA67T, D. riboflavina IFO13584T and D. indica IO390501T were 24.50, 21.8 and 24.80 %, respectively. The major polar lipids of strain SCS-3T were diphosphatidylglycerol, phosphatidylglycerol and three unidentified glycolipids. Ubiquinone-10 was the sole isoprenoid quinone, and C16 : 0, C18 : 1 ω7c 11-methyl and summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) were the major fatty acids. Based on polyphasic taxonomic data, strain SCS-3T represents a novel species of the genus Devosia , for which the name Devosia salina sp. nov. is proposed. The type strain is SCS-3T (=JCM 34403T=GDMCC 1.2221T).

“…S3). These polar lipid profiles of strains G2-5 T and G20-9 T were in line with those observed in other Devosia species [2,[4][5][6][7][8][9][10][11].…”

“…The respiratory isoprenoid quinones detected in strains G2-5 T and G20-9 T were identified as Q-10, which aligns with the predominant respiratory quinone observed in other species of the genus Devosia [4][5][6][7][8][9][10][11][12]. Regarding major fatty acids (those constituting >10 % of the total fatty acids), both strains exhibited summed feature 8 (comprising C 18 : 1 ω7c and/or C 18 : 1 ω6c), 11-methyl-C 18 : 1 ω7c and C 18 : 0 .…”

The members of the genus Devosia have been isolated from various environmental habitats, including alpine glacial cryoconite [2], marine sediments [4][5][6][7][8], horse blood [9], nitrifying inoculum [10], root nodules and soils [11,12], and medical leeches [13]. Members of the genus Devosia are Gram-stain-negative, aerobic, non-endospore-forming, oxidasepositive rod-shaped bacteria having ubiquinone-10 (Q-10) or ubiquinone-11 (Q-11) as the major respiratory quinone and DNA G+C contents ranging from 59.5 to 66.2 mol% [1,2,[4][5][6][7][8][9][10][11][12][13].…”
