Abstract
Na.tro.no.spi’ra. N.L. neut. n. natron (arbitrarily derived from the Arabic n. natrun or natron), soda; L. fem. n. spira, coil; N.L. fem. n. Natronospira, a soda-loving coil-shaped bacterium.
The genus Natronospira was originally classified as a member of the family Ectothiorhodospiraceae, order Chromatiales, and class Gammaproteobacteria, according to the 16S rRNA-based gene sequence comparison, while according to the phylogenomic analysis it forms a separate order-level branch within the Gammaproteobacteria unrelated to the Chromatiales members. It is an aerobic heterotroph that preferably utilizes proteins and peptides for growth. Natronospira is an extremely salt-tolerant, chloride-independent obligate alkaliphile. It inhabits oxic brines of hypersaline soda lakes, particularly in southwestern Siberia. The genus currently includes a single (type) species:
N. proteinivora. DNA G +C content (%): 59.8 (genome). Type species: Natronospira proteinivora Sorokin et al. 2017VP.
