Na.tro.no.cal’cu.lus N.L. neut. n. natron, arbitrarily derived from the Arabic natrun or natron, soda; L. masc. n. calculus, pebble, gravel; N.L. masc. n. Natronocalculus, soda-loving pebble-shaped cells. The genus Natronocalculus is a member of the family Halorubraceae, order Haloferacales, and class Halobacteria, according to the NCBI classification, while recent
changes in the taxonomy of the Halobacteria based on the Genome Taxonomy Database phylogenomic classification place Natronocalculus into the family Haloferacaceae, order Halobacteriales. The genus members are aerobic, extremely halophilic and moderately
alkaliphilic, and saccharolytic archaea, utilizing various alpha-glucans and sugars as carbon and energy sources. The genus currently includes a single species Natronocalculus amylovorans inhabiting hypersaline soda lakes. The genus three-letter abbreviation is Ncl.
DNA G +C content (mol%): 51.5 (whole-genome sequence of the type strain).
Type species: Natronocalculus amylovorans Sorokin et al. 2022, VL211.
