Summary: | A Gram-negative, facultatively anaerobic, motile bacterial strain, TPQG1-4
T
, was isolated from the leaf of
Cyclobalanopsis patelliformis
with spot disease. The isolate was investigated using the polyphasic taxonomic approach. 16S rRNA gene sequencing and analyzing revealed that the novel strain shares the highest sequence similarity with
Stenotrophomonas lactitubi
M15
T
(99.6%),
Stenotrophomonas indicatrix
WS40
T
(99.4%),
Stenotrophomonas maltophilia
IAM 12423
T
(99.2%) and
Stenotrophomonas pavanii
LMG 25348
T
(99.0%). In phylogenetic trees based on 16S rRNA gene sequences, the novel strain branched independently from other species of
Stenotrophomonas.
Average nucleotide identity values between the novel isolate and
S. lactitubi
M15
T
,
S. indicatrix
WS40

,
S. maltophilia
IAM 12423

S. pavanii

T
, and
Pseudomonas geniculata
ATCC 19374
T
were 87.2%, 87.3%, 86.3%, 88.0%, and 81.3%, respectively, suggesting the isolate was a novel species of the genus
Stenotrophomonas.
The DNA G + C content of TPQG1-4
T
is 67.1 mol%. The major fatty acids were iso-C
15:0
(25.4%) and anteiso-C
15:0
(17.0%). The polar lipids of TPQG1-4
T
included phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, amino phospholipid and phospholipid. Based on phenotypic and genotypic characteristics, the strain represents a novel species in the genus
Stenotrophomonas
, for which the name
Stenotrophomonas cyclobalanopsidis
sp. nov. is proposed. The type strain is TPQG1-4
