Ha.lo.plas.ma.ta’ce.ae. N.L. n. Haloplasma, type genus of the family; suff. -aceae, ending denoting an order; N.L. fem. pl. n. Haloplasmataceae, the Haloplasma family. Pleomorphic cells, usually with contractile “tentaclelike” protrusions. Motile by cellular contraction. Non-spore-forming. Strictly anaerobic. Strictly organotrophic. Denitrifying and fermentative. Only able to metabolize a very restricted range of carbon sources (L-arabinose, D-psicose, α-ketobutyric acid, α-ketoglutaric acid, and α-ketovaleric acid). Cell wall is not detected. The predominant fatty acids (>10%) are C16:0, C18:0, C18:1 ω9c, and summed feature 5 (most likely C18:2 ω6,9c). The major polar lipids are phosphatidylglycerol and biphosphatidylglycerol. The major respiratory quinone is MK-4. Phylogenetically a member of the phylum “Firmicutes,” the sole family of the order Haloplasmatales, and includes only the monospecific genus Haloplasma. Otherwise, the description of the family is the same as for the genus Haloplasma. DNA G+C content (mol%): 33.6 (HPLC), 33.0 (draft genome). Type genus: Haloplasma Antunes, Rainey, da Costa and Huber 2008a, 2476VP (Effective publication: Antunes, Rainey, Wanner, Taborda, Pätzold, Nobre, da Costa and Huber 2008b, 3586).
