To date, there is only one cultivated strain in the family
Kiritimatiellaceae
, the type strain of
Kiritimatiella glycovorans
(Spring et al., 2016). Microorganisms assigned to this family are generally free‐living, nonmotile, non‐spore‐forming, coccoid bacteria adapted to anoxic aquatic niches characterized by hypersaline conditions. Other features include cell division by binary fission, a Gram‐negative type cell wall containing peptidoglycan, no intracellular membranes, and an anaerobic metabolism based on the fermentation of carbohydrates. The main nongaseous fermentation products are ethanol and acetate. Transparent exopolymers are formed and probably protect cells from desiccation in hypersaline environments. Cellular fatty acid patterns are dominated by straight‐chain (C
18:0
) and iso‐branched fatty acids (iso‐C
14:0
). The major polar lipid was identified as phosphatidylglycerol (PG) besides minor amounts of an unidentified phospholipid, two distinct glycolipids, an aminolipid and small amounts of phosphoglycolipids. The genome size of the only described type strain of this family is 2.9 Mb.
