Title: Aeromicrobium halotolerans sp. nov., isolated from desert soil sample. Author: Yan ZF, Lin P, Chu X, Kook M, Li CT, Yi TH. Journal: Arch Microbiol; 2016 Jul; 198(5):423-7. PubMed ID: 26892181. Abstract: 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 °C (optimum at 30 °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, C16:0, C18:1 ω9c and 10-methyl C18:0 (>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)).[Abstract] [Full Text] [Related] [New Search]
