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).
