Verrucomicrobiota / Tichowtungiia / Tichowtungiales / Tichowtungiaceae
The species in
Tichowtungiaceae
are anaerobic, nonmotile, coccoid, Gram‐stain‐negative, and isolated from surface marine sediments. They are also non‐spore‐forming and arranged singularly or in pairs. Cells grow poorly under low oxygen conditions. Respiratory lipoquinones are not formed during anaerobic cultivation. The major cellular fatty acids are C

, iso‐C

, iso‐C

, and iso‐C

. The major polar lipids include diphosphatidylglycerol and phosphatidylglycerol. Phylogenetic analyses based on 16S rRNA genes and genome sequences indicate that
Tichowtungiaceae
branches within the radiation of the group
Kiritimatiellia
. The genus
Pontiella
can be considered to be within the family
Tichowtungiaceae
based on the positions of
Tichowtungia aerotolerans
S‐5007
T
and species of the genus
Pontiella
in the phylogenetic tree. However, some authors consider
Pontiella
a member of a separate family.
