Abstract

A red-pigmented, Gram-reaction-negative, aerobic bacterial strain, designated No.164, was isolated from sediment sample from the alkaline Lake Elmenteita located in the Kenyan Rift Valley. Results of 16S rRNA gene sequence analysis indicated that the isolate represented a member of the genus , with the highest sequence similarity (97 %) to DSM 46698. Optimal growth temperature was 30–35 °C, at pH 7.0–12.0 in the presence of 0–4 % (w/v) NaCl. Flexirubins were absent. The respiratory menaquinone (MK-7), predominant cellular fatty acids (iso-C, anteiso-C and a mixture of Cω7 and/or iso-C 2-OH) and DNA G+C content (38.1 mol%) of strain No.164 were consistent with those of other members of the genus . The polar lipids consisted of phosphatidylethanolamine, eight unspecified lipids and one unspecified phospholipid. Several phenotypic characteristics can be used to differentiate this isolate from those of other species of the genus . The results of polyphasic analyses presented in this study indicated that this isolate should be classified as representing a novel species of the genus . The name sp. nov. is therefore proposed; the type strain is strain No.164 ( = DSM 46651 = CECT 8551).
