Abstract
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:

Costa and Huber 2008b, 3586).
