Natronocella

Abstract

Abstract Na.tro.no.cel'la; N.L. neut. n. natron (arbitrarily derived from the Arabic n. natrun or natron), soda, sodium carbonate; N.L. pref. natrono ‐, pertaining to soda; L. fem. n. cella , a room, a cell in biology; N.L. fem. n. Natronocella , a soda‐loving cell. Proteobacteria / Gammaproteobacteria / Nitrococcales / Aquisalimonadaceae / Natronocella The genus Natronocella comprise aerobic heterotrophs that utilizes short‐chain nitriles and their corresponding fatty acids and amides as energy, carbon, and nitrogen sources. Natronocella is a moderately salt‐tolerant, chloride‐independent obligate alkaliphile inhabiting soda lakes in Central Asia. The genus currently includes a single species N. acetinitrilica . It was originally classified as a member of the family Ectothiorhodospiraceae , order Chromatiales , class Gammaproteobacteria , but more recent phylogenomic analyses classify it in the proposed order “ Nitrococcales ” and family “ Aquisalimonadaceae .” DNA G + C content (%) : 63.0 (genome sequence). Type species : Natronocella acetinitrilica Sorokin et al. 2007, VL116.
