natrinema natrinema natrinema (common abbreviation nnm.) is a genus of the natrialbaceae. natrinema scientific classification domain: archaea kingdom: euryarchaeota phylum: euryarchaeota class: halobacteria order: natrialbales family: natrialbaceae genus: natrinemamcgenity et al. 1998 species n. altunense n. amylolyticum n. ejinorense n. gari n. halophilum n. hispanicum n. limicola n. longum n. mahii n. pallidum n. pellirubrum n. saccharevitans n. salaciae n. salifodinae n. salinisoli n. soli n. thermotolerans n. versiforme taxonomy as of 2022, there are 18 species validly published in the genus natrinema. natrinema is related to the genus haloterrigena, established in 1999, resulting in confusion about taxon limits and several species apparently being assigned to the wrong genus. based on phylogenomic analysis, eight species from haloterrigena as well as halopiger salifodinae were transferred to natrinema in 2022.
