Jiangella anatolica sp. nov. isolated from coastal lake soil

A novel actinobacterial strain, designated GTF31T, was isolated from a coastal soil sample of Gölcük Lake, a crater lake in southwest Anatolia, Turkey. The taxonomic position of the strain was established using a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequences and showed that the strain is closely related to Jiangella gansuensis DSM 44835T (99.4%), Jiangella alba DSM 45237T (99.3%) and Jiangella muralis DSM 45357T (99.2%). Optimal growth was observed at 28 °C and pH 7–8. Whole cell hydrolysates were found to contain LL-DAP, glucose, mannose, rhamnose and ribose. The predominant menaquinone was identified as MK-9(H4). The polar lipid profile was found to contain diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycophospholipids and unidentified phospholipids. The major fatty acids were identified as anteiso-C15:0, iso-C16:0 and anteiso-C17:0. The G + C content of the type strain was determined to be 72.5% and the size of the draft genome is 7.0 Mb. The calculated digital DDH values between strain GTF31T and the type strains of J. gansuensis, J. alba, J. muralis and Jiangella alkaliphila ranged from 24.4 to 34.4% and ANI values ranged between 81.0 and 87.9%. Based upon the consensus of phenotypic and phylogenetic analyses as well as whole genome comparisons, strain GTF31T (= DSM 100984T = CECT 9378T) is proposed to represent the type strain of a novel species, Jiangella anatolica sp. nov.
