Abstract |
A Gram-negative, facultatively anaerobic, non-motile, nonspore-
forming, coccoid or rod-shaped and creamy-pigmented
bacterium, designated SYP-B2100T, was isolated from the rhizospheric
soil of Codonopsis clematidea in the Xinjiang Uygur
Autonomous Region, China. The optimal growth occurred
at 28°C, pH 5.0, in the absence of NaCl. The cells tested positive
in catalase and methyl red tests but negative in oxidase,
urease, gelatinase, milk coagulation, and peptonisation, H2S
production, nitrate reduction, and Voges-Proskauer tests. The
major isoprenoid quinone was ubiquinone-8 (Q-8). The major
cellular fatty acids were C16:0 and summed feature 8. The
polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine,
and phosphatidylglycerol. The 16S rRNA
gene sequence of strain SYP-B2100T was the most similar to
that of Rahnella inusitata DSM 30078T (96.9%) within the
family Enterobacteriaceae. The genomic DNA G+C content
of strain SYP-B2100T was 50.3 mol%. The combined data from
the phylogenetic, morphological, physiological, biochemical,
and chemotaxonomic analyses presented in this study support
the conclusion that strain SYP-B2100T represents a novel
species of a new genus, for which the name Edaphovirga cremea
gen. nov., sp. nov. is proposed; the type strain is SYPB2100T
(= CGMCC 1.5857T = DSM 105170T = KCTC 62024T). |
