Kaistella gelatinilytica sp. nov., a flavobacterium isolated from Antarctic soil
A Gram-stain-negative, aerobic, non-spore-forming, rod-shaped, non-motile, yellow-pigmented bacteria, designated strain G5-32 , belonging to the genus was isolated from soil collected in the Antarctic. The strain was identified using a polyphasic taxonomic approach. The strain grew in the presence o...

Zusammenfassung: | A Gram-stain-negative, aerobic, non-spore-forming, rod-shaped, non-motile, yellow-pigmented bacteria, designated strain G5-32
, belonging to the genus
was isolated from soil collected in the Antarctic. The strain was identified using a polyphasic taxonomic approach. The strain grew in the presence of 0-5% (w/v) NaCl (optimum, 1%), at pH 6.0-9.0 (optimum, pH 8.0) and at 4-28 °C (optimum, 20 °C). The predominant menaquinone was MK-6 (99.4%). The major fatty acids were anteiso-C
(28.2%), iso-C
(16.4%), summed feature 9 (comprising iso-C
9
and/or 10-methyl C
; 10.6%) and iso-C
(5.9%). A phylogenetic tree based on 16S rRNA gene sequences showed that strain G5-32
formed a lineage within the genus
with the closest phylogenetic neighbours
HMD1043
,
DSM 23145
,
DSM 17048
and
NCTC 13525
(97.9, 97.8, 97.8 and 98.0 % 16S rRNA gene sequence similarity, respectively). The ANI values between strain G5-32
and
DSM 17048
,
DSM 23145
,
NCTC 13525
and
HMD1043
were 90.9, 82.6, 77.1 and 76.3%. Concurrently, digital DNA-DNA hybridization values of strain G5-32
assessed against
DSM 17048
,
DSM 23145
,
NCTC 13525
and
HMD1043
were 42.3, 25.9, 21.7 and 21.3%, respectively. Based on phenotypic, phylogenetic and genotypic data, a novel species,
sp. nov., is proposed. The type strain is G5-32
(=CCTCC AA 2019083
=KCTC 72766
). |
