Nanosalinicola
a dwarf‐sized organism inhabiting saltworks.
The genus
Candidatus
Nanosalinicola corrig., originally described as
Candidatus
Nanosalinarum, was established based on a sequence from a metagenome recovered from the hypersaline Lake Tyrrell in Victoria, Australia.
Ca
. Nanosalinicola is phylogenetically affiliated with members of the
Candidatus
Nanohaloarchaeota branch (
Candidatus
Nanosalina,
Candidatus
Nanopetraeus corrig., and
Candidatus
Haloredivivus) of the archaeal DPANN superphylum. On the basis of fluorescence
in situ
hybridization, cells are ∼0.6 μm in diameter. Analysis of the ∼1.22 Mb genome of
Ca
. Nanosalinicola J07AB56 with 56% DNA G + C suggests that the organism is an aerobic photoheterotroph. The high proportion of acidic amino acids of the predicted proteins suggests a “salt‐in” strategy for osmotic balance. Gene sequences affiliated with
Ca
. Nanosalinicola have also been recovered from coastal salterns in Australia and California, USA.
DNA G + C content (mol%)
: 56 (genome sequence).
Type species
: Not assigned.
Genome sequence
: AEIX00000000.
