Aeromicrobium halotolerans sp. nov., isolated from desert soil sample
Yan, Zheng-Fei,Lin, Pei,Chu, Xiao,Kook, MooChang,Li, Chang-Tian,Yi, Tae-Hoo Springer-Verlag 2016 Archives of microbiology Vol.198 No.5
<P>A Gram-positive, aerobic, and non-motile, rod-shaped actinomycete strain, designated YIM Y47(T), was isolated from soils collected from Turpan desert, China, and subjected to a polyphasic taxonomic study. Phylogenetic analysis indicated that strain YIM Y47(T) belonged to the genus Aeromicrobium. YIM Y47(T) shared highest 16S rRNA gene sequence similarities with Aeromicrobium massiliense JC14(T) (96.47 %). Growth occurs at 20-45 A degrees C (optimum at 30 A degrees C), pH 6.0-8.0 (optimum at pH 7.0), and salinities of 0-7.0 % NaCl (optimum at 4.0 %). The strain YIM Y47(T) exhibits chemotaxonomic features with menaquinone-7 (MK-7) as the predominant quinone, C-16:0, C-18:1 omega 9c and 10-methyl C-18:0 (> 10 %) as major fatty acids. The cell-wall peptidoglycan of strain YIM Y47(T) contained ll-diaminopimelic acid as the diagnostic diamino acid. The polar lipids were found to consist of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, and unknown phospholipids. The G+C content of the genomic DNA of strain YIM Y47(T) was found to be 44.7 mol%. On the basis of phylogenetic analyses and phenotypic data, it is proposed that strain YIM Y47(T) should be classified as representing a novel species of the genus Aeromicrobium, with the name Aeromicrobium halotolerans sp. nov. The type strain is YIM Y47(T) (=KCTC 39113(T)=CGMCC 1.15063(T)=DSM 29939(T)=JCM 30627(T)).</P>

<P>A Gram-negative, aerobic, non-motile, long rods or coccoid without flagellum strain, designated THG-YS3.2.7(T), was isolated from therhizosphere soil of a Mugunghwa flower collected from Kyung Hee University, Yongin, South Korea. Growth occurred at 10-40 degrees C (optimum 28-37 degrees C), at pH 6-8 (optimum 7) and at 0-5% NaCl (optimum 1 %). The predominant ubiquinone was ubiquinone 8 (Q-8). The major cellular fatty acids were C-10 : 0, C-10 : 0 3OH, C-16 : 0, C-17 : 0, C-17 : 0 cyclo, C-18 : 0, C(18 : 3 omega)6c (6,9,12), summed feature 3 (C-16 (: 1)omega 7c and/or C-16 : 1 omega 6c) and summed feature 8 (C-18 : 1 omega 7c and/or C-18 : 1 omega 6c). The major polar lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), phosphatidylcholine (PC). The DNA G+C content of strain THG-YS3.2.7(T) was 69.4 mol%. Based on 16S rRNA gene sequence analysis, the nearest phylogenetic neighbours of strain THG-YS3.2.7(T) were identified as Ramlibacter henchirensis DSM 14656(T) (97.92 %), Ramlibacter tataouinensis DSM 14655(T) (97.90 %), Ramlibacter solisilvae KACC 17567(T) (97.04 %). DNA-DNA hybridization values between strain THG-YS3.2.7(T) and R. henchirensis DSM 14656(T), R. tataouinensis DSM 14655(T), R. solisilvae KACC 17567(T) were 32.5 +/- 1.5, 43.1 +/- 1.1, 42.8 +/- 1.1 %, respectively. On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain THG-YS3.2.7(T) represent a novel species of the genus Ramlibacter, for which the name Ramlibacter rhizophilus sp. nov. is proposed. The type strain is THG-YS3.2.7(T) (= KCTC 52083(T) = CCTCC AB 2015357(T)).</P>
Altererythrobacter deserti sp. nov., isolated from desert soil

<P>A Gram-stain-negative, aerobic, short rod-shaped, non-motile bacterium (THG-S3(T)), was isolated from desert soil. Growth occurred at 15-35 degrees C (optimum 28 degrees C), at pH 5-10 (optimum 7) and at 0-4% NaCl (optimum 1 %). Based on 16S rRNA gene sequence analysis, the nearest phylogenetic neighbours of strain THG-S3(T) were identified as Altererythrobacter rigui KCTC 42620(T) (99.0 %), Altererythrobacter dongtanensis KCTC 22672(T) (97.1 %), Altererythrobacter xinjiangensis CCTCC AB 207166(T) (96.9 %), Altererythrobacter troitsensis KCTC 12303(T) (96.9 %). Levels of relatedness among strain THG-S3(T) and other Altererythrobacter species were lower than 96.0 %. DNA-DNA hybridization values between strain THG-S3(T) and A. rigui KCTC 42620(T), A. dongtanensis KCTC 22672(T), A. xinjiangensis CCTCC AB 207166(T) and A. troitsensis KCTC 12303(T) were 59.7% (42.8 %, reciprocal analysis), 45.1% (36.3 %), 34.7% (25.1 %) and 15.1% (12.3 %), respectively. The DNA G+C content of strain THG-S3(T) was 69 mol%. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and three unidentified lipids The quinone was ubiquinone-10. The major fatty acids were C-16 : 0, C-17 : 1 omega 6c, C-18 : 1 omega 7c and summed feature 3 (C-16 : 1 omega 7c and/or C-16 : 1 omega 6c). On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain THG-S3(T) represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter deserti sp. nov. is proposed. The type strain is THG-S3(T) (=KACC 19190(T) = CGMCC 1.15959(T)).</P>
