Abstract
Sci.sci.o.nel'la. N.L. fem. dim. n.
Sciscionella
arbitrary name formed from the acronym of the South China Sea Institute of Oceanology, SCISCIO, where taxonomic studies on this taxon were performed.
The genus
Sciscionella
is classified as a member of the family
Pseudonocardiaceae
, order
Pseudonocardiales
, and in the class
Actinobacteria
. The member of this genus has a 16S rRNA sequence identity of less than 94% with the other members of the family
Pseudonocardiaceae
. In the phylogenetic tree based on 16S rRNA gene sequences, the single member of this genus,
Sciscionella marina
, forms a distant clade, closely related to the genera
Haloechinothrix, Thermocrispum
, and
Yuhushiella
. Cells are characterized with cell‐wall chemotype IV and phospholipid pattern type III
sensu
Lechevalier et al. 1977. The predominant respiratory quinone is MK‐9(H
4
), and the fatty acid composition is dominated by saturated branched‐chain fatty acids, but not mycolic acids. Phenotypically, strains are aerobic and stain Gram‐positive. They could grow at 10–37°C, pH 6.0–8.0, and in the presence of up to 13% NaCl (w/v). The genus comprises one species,
Sciscionella marina
(the type species of the genus).
