sp. nov. and sp. nov., two novel species isolated from the shore soil of salt lake.

Six Gram-staining-negative, aerobic, non-motile and rod-shaped bacterial strains, designated as D3-2-R+10, C2-6-M1, E1-3-M2, D2-2-M3, D2-2-M2 and D2-2-M1, were isolated from the shore soil of LungmuCo Lake in Xizang Autonomous Region, China. The 16S rRNA gene sequence comparisons confirmed that the six isolates belonged to the genus of the family . The 16S rRNA gene sequence of strains D3-2-R+10, D2-2-M3, D2-2-M2 and D2-2-M1 exhibited the highest similarities to the type strains of LMG 21980(98.1-98.5 %) and NH1 (97.9-98.4 %). Meanwhile, the 16S rRNA gene sequence of strains C2-6-M1 and E1-3-M2 showed the highest similarities to LMG 21980 (98.2-98.7%). The average nt identity and digital DNA-DNA hybridization values among strains D3-2-R+10 and C2-6-M1 and their most closely related species LMG 21980 were all lower than the threshold values for delineating species, indicating that they represent two separate novel species of . The predominant cellular fatty acids of strains D3-2-R+10 and C2-6-M1 included iso-C, summed feature 3 (C 7/C c) and summed feature 9 (iso-C 9/C 10-methyl), and the predominant respiratory quinone was MK-7. The major polar lipids of strain D3-2-R+10 comprised phosphatidylethanolamine, one unidentified phospholipid and five unidentified lipids, while those of strain C2-6-M1 included phosphatidylethanolamine, two unidentified phospholipids and seven unidentified lipids. The genome size of strains D3-2-R+10 and C2-6-M1 was 6.0 and 5.0 Mb, respectively, with the DNA G+C contents of 40.1 and 40.9 mol %. Based on the above descriptions, the six strains were identified as two novel species of the genus , for which the names sp. nov. and sp. nov. were proposed, with the type strains, respectively.
