Abstract

Abstract Natr.ar.chae.o.ba'cu.lum. N.L. neut. n. natron, pertaining to soda; Gr. masc. adj. archaîos ancient; L. neut. n. baculum, small stick, rod; N.L. neut. n. Natrarchaeobaculum soda‐loving archaeal rod. Halobacteriota / Halobacteria / Natrialbales / Natrialbaceae / Natrarchaeobaculum The genus Natrarchaeobaculum is classified as a member of the family Natrialbaceae , order Natrialbales , class Halobacteria according to phylogenomic analyses. It includes extremely halophilic heterotrophic natronoarchaea, some of which can grow anaerobically by sulfur respiration utilizing organic acids, H 2 , and formate as the electron donors. The genus currently includes two species: the facultatively anaerobic type species Natrarchaeobaculum sulfurireducens and the aerobic species Natrarchaeobaculum aegyptiacus . These species inhabit hypersaline soda lakes. The three letter abbreviation is Nab . DNA G + C content (mol%) : 62.8–64.1 (whole genome sequences). Type species : Natrarchaeobaculum sulfurireducens Sorokin et al. 2020a VP .
