sp. nov., isolated from the xylem tissues of eucalyptus No Access

Abstract

A Gram-stain-negative, aerobic, ovoid or rod-shaped, non-spore-forming, motile with peritrichous flagella bacterium, designated strain N3-1-1-11, was isolated from the xylem tissues of × in Qinzhou, Guangxi Province, China. Optimal growth occurred at 28 °C, at pH 6.0 and in the presence of 0–1% (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that N3-1-1-11 was clustered with species of the genus and formed a distinct sublineage, showing the highest similarities to PML1(12) (98.48%), LMG 27134 (97.99%) and LMG 22029 (97.86%). The predominant ubiquinone is Q-8. The major fatty acids are C, C , summed feature 3 (C and/or C ) and C . The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and aminophospholipid. The DNA G+C content was 59.33 mol%. The phylogenetic analysis and physiological and biochemical data showed that strain N3-1-1-11 should be classified as representing a novel species in the genus , for which the name sp. nov. is proposed. The type strain of is N3-1-1-11 (=CFCC 15711=CGMCC 1.65219=KCTC 8740).
