Abstract
T Strain DSM 17733(T), isolated from the shore of Lake Abjata in Ethiopia, is a heterotrophic, alkaliphilic, moderately halophilic, Gram-positive, strictly aerobic, non-motile, non-endospore-forming bacterium. The organism grows optimally at 30-37 degrees C, pH 9 and 3 % (w/v) NaCl. Analysis of the cell wall showed the presence of murein of the type L-Lys-Gly-L-Glu, variation A4 alpha. The G + C content of the genomic DNA was 69(.)0 mol%. Sequence analysis of 16S rRNA gene sequence of strain DSM 17733(T) placed the isolate in the genus Nesterenkonia. DNA-DNA hybridization of DSM 17733(T) with those organisms with the closest phylogenetic affiliation, i.e. Nesterenkonia halobia, Nesterenkonia facusekhoensis and Nesterenkonia xinjiangensis,...

The G + C content of the genomic DNA was 69(.)0 mol%. Sequence analysis of 16S rRNA gene sequence of strain DSM 17733(T) placed the isolate in the genus Nesterenkonia. DNA-DNA hybridization of DSM 17733(T) with those organisms with the closest phylogenetic affiliation, i.e. Nesterenkonia halobia, Nesterenkonia facusekhoensis and Nesterenkonia xinjiangensis, gave relatedness values of 48.5 %, 63(.)7 % (repetition, 57(.)2 %) and 35(.)7 % (repetition, 29(.)3 %), respectively. On the basis of both phenotypic and phylogenetic criteria and the low levels of DNA-DNA relatedness with the phylogenetically closest species N. xinjiangensis and N. halobia, it is proposed that the isolate be classified in a novel species, Nesterenkonia aethiopica sp. nov. The type strain is DSM 17733(T) (=CCUG 48939(T)). (Less)
