Abstract
A Gram-stain-negative, yellow-pigmented bacterium, designated as L7T, was isolated from seeds of Alhagi sparsifolia Shap., a leguminous plant that grows in northwest PR China. Strain L7T was found to be non-flagellated, non-spore forming rods which can grow at 10–37 °C, pH 6.0–8.5 and in 0–3 % (v/w) NaCl concentration. The 16S rRNA gene sequence analysis showed that strain L7T belongs to the genus
Chryseobacterium
with sequence similarities to
Chryseobacterium vietnamense
GIMN1.005T (98.1%),
C. bernardetii
NCCTC13530T (98.0%),
C. vrystaatense
LMG 22846T (97.9%),
C. nakagawai
NCTC13529T (97.7%),
C. shigense
DSM 17126T (97.6%) and
C. rhizosphaerae
RSB3-1T (97.5%). The average nucleotide identity of strain L7T to 31 reference strains were 78.6–85.6 %, lower than the species delineation threshold of 95 %. MK-6 was the only respiratory quinone of L7T and major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 1
ω7c and/or C16 : 1
ω6c, isoC17 : 1
ω9c and/or C16 : 0 10-methyl. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, three unidentified aminophospholipids, two unidentified aminolipids, three unidentified glycolipids and two unidentified lipids. The G+C content of the genome was 38.58 mol%. On the basis of polyphasic taxonomy analyses in this study, strain L7T is considered to represent a novel species in the genus
Chryseobacterium
, for which the name Chryseobacterium endalhagicum sp. nov. is proposed. The type strain is L7T (=MCCC 1K05687T=JCM 34506T)
