| Popis: | A salt-tolerant, Gram-negative, rod-shaped and yellow-pigmented bacterium, designated strain AY-3RT, was isolated from rhizosphere soil of a desert xerophyte, Haloxylon ammodendron, sampled at Badain Jaran Desert, Alxa region, Inner Mongolia, PR China. Growth of this strain was observed at 20–42 °C (optimum, 28–30 °C), at pH 6.0–9.0 (optimum, pH 6.0–7.0) and at 0–8 % (w/v) NaCl (optimum, 3 %). Results of phylogenetic analysis based on 16S rRNA gene sequences showed that strain AY-3RT was a member of the genus Altererythrobacter , with the highest similarity to Altererythrobacter aerophilus Ery1T (97.6 %), followed by Altererythrobacter xinjiangensis S3-63T (96.9 %). The predominant fatty acids (>10.0 %) were C18 : 1ω7c, C17 : 1ω6c and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid and one unknown polar lipid. The predominant respiratory quinone was ubiquinone-10. The G+C content of the genomic DNA of strain AY-3RT was 66.3 mol%. On the basis of the data from this polyphasic taxonomic study, strain AY-3RT represents a novel species of the genus Altererythrobacter , named Altererythrobacter rhizovicinus sp. nov. (=MCCC 1K03572T=KCTC 72280T). |
