- Abstract
A Gram-positive, aerobic, and non-motile, rod-shaped actinomycete strain, designated YIM Y47, was isolated from soils collected from Turpan desert, China, and subjected to a polyphasic taxonomic study. Phylogenetic analysis indicated that strain YIM Y47 belonged to the genus Aeromicrobium. YIM Y47 shared highest 16S rRNA gene sequence similarities with Aeromicrobium massiliense JC14 (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 exhibits chemotaxonomic features with menaquinone-7 (MK-7) as the predominant quinone, C, C ω9 c and 10-methyl C (>10 %) as major fatty acids. The cell-wall peptidoglycan of strain YIM Y47 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 was found to be 44.7 mol%. On the basis of phylogenetic analyses and phenotypic data, it is proposed that strain YIM Y47 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 (=KCTC 39113=CGMCC 1.15063=DSM 29939=JCM 30627).
