摘要： A novel bacterium, designated STR12T, was isolated from the soil of a moso bamboo (Phyllostachys edulis) forest in Hangzhou, China. The strain was a Gram-stain-negative, rod-shaped, motile bacterium; the colonies of which were yellow, round, flat, sticky, and non-moist with a smooth margin after cultivation for 3 days at 28 degrees C. The strain grew at temperatures between 15 and 37 degrees C (optimum, 28 degrees C), pH values from 4.0 to 8.0 (optimum, pH 7.0), and salinities ranging from 0 to 5% (w/v) NaCl (optimum, 1%). Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the strain was grouped within a cluster of the genus Frateuria, showing the highest similarity with Frateuria flava MAH-13T (97.7%). The genome of strain STR12T was 3.74 Mb in length with a G+C content of 67.9%. Genome comparisons of strain STR12T with other species within the genus Frateuria revealed that the range of average nucleotide identity, DNA-DNA hybridization, and average amino acid identity values were 73.9-85.9%, 20.8-30.7%, and 62.7-86.7%, respectively, all of those were below the respective prokaryotic species delineation thresholds. The predominant quinone in strain STR12T was ubiquinone-8 and the major fatty acids were iso-C15:0, iso-C16:0, iso-C17:0, and Summed Feature 9. Polar lipids included diphosphatidylglycerol, phosphatidylethanolamine, two unidentified aminophospholipids, and one unidentified phosphoglycolipid. On basis of the finding of phylogenetic, physiological, and chemotaxonomic analyses, we proposed the name Frateuria hangzhouensis sp. nov. for the novel species in the genus Frateuria, of which the type strain was strain STR12T (= ACCC 61897T = GDMCC 1.2964T = JCM 35226T).
