Abstract
A bacterial strain designated E-48T was isolated from Lake Elmenteita, an alkaline saline lake within the East African rift valley. The cells were Gram-negative, motile, non-spore forming rods. Growth was observed at a pH range between 6.0 and 13.0 (optimum pH 9.5), salt concentration (w/v) up to 20% (optimum 5%) and the temperature for growth was between 14.0-44°C (optimum temperature 36°C). On the basis of 16S rRNA gene sequence similarity (99%), strain E-48T belonged to the genus Nitrincola (family Oceanospirillaceae, class Gammaproteobacteria). The DNA GC content was 46.4 mol%. The major cellular fatty acid was the mono-unsaturated 18:1 ω7c while the major isoprenoid quinone was Q-8. However, at the genome level, strain E-48T had a G+C difference of 7.17% from the genome of N. lacisaponensis DSM 16316T. Based on the various characteristics, it is proposed that the isolate represents a new species within the genus Nitrincola for which the name Nitrincola elmenteitensis is proposed. The type strain is E-48T (=DSM 26266T=LMG 28382T).

Summary
The genus Nitrincola (Dimitriu et al, 2005) in the family of Oceanospirillaceae is currently comprised of five validly published species. Nitrincola lacisaponensis is the type species of this genus and was isolated from decayed wood collected at a meromictic alkaline saline lake in the USA (Dimitriu et al, 2005). N. alkalisediminis was isolated from the alkaline Lonar Lake in Maharashtra, India (Joshi, A. et al, 2016) while Nitrincola schmidtii and Nitrincola alkalilacustris (Borsodi et al, 2017) were recovered from soda pans located in the Kiskunság National Park, Hungary. Nitrincola tibetensis xg18T was isolated from Lake XuguoCo on the Tibetan Plateau (Phurbu et al, 2019). Nitrincola nitratireducens AK23T is an effectively but not validly published species isolated from Lonar Lake, Buldhana district, India (Singh et al, 2015). We describe a novel E-48T isolated from the haloalkaline Lake Elmenteita in Kenya
