Abstract
A Gram-stain-positive, aerobic, non-motile, coryneform bacterium, designated strain EGI 60002
T
, was isolated from the halophyte
Suaeda physophora
. Cells were coryneform shaped and polymorphic. Phylogenetic analysis based on 16S rRNA gene sequences showed that the new isolate was closely related to
Actinotalea ferrariae
CF5-4
T
(95.8 % gene sequence similarity). The peptidoglycan type of strain EGI 60002
T
was A4
β
, containing
l
-Orn-
d
-Ser-
d
-Asp. The cell-wall sugars were mannose, ribose, rhamnose and glucose. The major fatty acids (>5 %) of strain EGI 60002
T
were iso-C
14:0
, iso-C
15:0
, anteiso-C
15:1
A and anteiso-C
15:0
. The predominant respiratory quinone was MK-10(H
4
). The major polar lipids were diphosphatidylglycerol (DPG), one unidentified phosphoglycolipid (PGL) and one unidentified phospholipid (PL1). The genomic DNA G+C content was 72.3 mol%. On the basis of morphological, physiological, chemotaxonomic data, and phylogenetic analysis, strain EGI 60002
T
should be classified as a novel species within the genus
Actinotalea
, for which the name
Actinotalea suaedae
sp. nov. is proposed. The type strain is EGI 60002T (=JCM 19624
T
= KACC 17839
