A taxonomic study was carried out on strain YQH10T, which was isolated from mangrove sediment collected from Zhangzhou, China during the screening of acetaldehyde-degrading bacteria. Cells of strain YQH10T were Gram-stain-negative rods and pale brown-pigmented. Growth was observed at salinities from 0 to 11 % and at temperatures from 4 to 42 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YQH10T is affiliated to the genus Shewanella, showing the highest similarity with Shewanella haliotis DW01T (95.7 %) and other species of the genus Shewanella (91.4–95.6 %). The principal fatty acids were iso-C15 : 0 and C17 : 1ω8c. The major respiratory quinone was Q-8. The polar lipids comprised phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA had a G+C content of 48.3 mol%. Strain YQH10T can completely degrade 0.02 % (w/v) acetaldehyde on 2216E at 28 °C within 48 h. Based on these phenotypic and genotypic data, strain YQH10T represents a novel species of the genus Shewanella, for which the name Shewanella mangrovi sp. nov. is proposed. The type strain is YQH10T ( = MCCC 1A00830T = JCM 30121T).

Twelve Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and motile strains (CY7WT, CY18WT, CY22WT, FT31WT, FT137WT, FT147WT, BYS50W, BYS107WT, LFS511WT, LX15WT, LX22WT and NL8WT) were isolated from streams in China. Comparisons based on 16S rRNA gene sequences indicated that these strains take species of genus Undibacterium as close neighbours. The reconstructed phylogenetic and phylogenomic trees also showed that these strains cluster with species of genus Undibacterium together. The genome G+C contents of these strains were in the range of 45.3 to 53.3 mol%. The calculated pairwise OrthoANIu values and digital DNA–DNA hybridization values among these strains and related strains were in the range of 70.4 to 94.1% and 19.3 to 55.3% except that the values between strains CY7WT and BYS50W were 99.0 and 91.8 %, respectively. Q-8 was their predominant respiratory quinone. C16 : 1  ω7c and C16 : 0 were their major fatty acids. Their polar lipids profiles were similar, including phosphatidylglycerol, phosphatidylethanolamine, one unidentified phospholipid and two kinds of unidentified aminolipids.
