Abstract

Na.tro.no.bi.for’ma. Gr. neut. n. natron arbitrarily derived from Arabic n. natrun or natron soda; L. adv. num. bis twice; L. fem. n. forma form, shape; N.L. fem.
n. Natronobiforma the dimorphic natronoarchaeon. The genus Natronobiforma, classified within the family Natrialbaceae, order Natrialbales, in the class
Halobacteria, currently consists of a single species, Natronobiforma cellulositropha. It is a moderately alkaliphilic, obligately aerobic, extreme halophile, forming pink colonies with large clearance zones on plates
containing amorphous cellulose. The cells are pleomorphic flat motile rods or nonmotile coccoid cells. Multiple strains classified within this genus were isolated
from alkaline hypersaline lakes in different locations. They grow optimally on insoluble native celluloses. Xylan, β-mannan, cellobiose, and maltose can also be used as carbon and energy sources. Other organic compounds used by most members of the Halobacteria do not support growth. DNA G+C content (mol%): 65.4–65.5 (genome sequences).
Type species: Natronobiforma cellulositropha Sorokin et al. 2019, VL187.
