Abstract
A novel Gram-staining-negative, non-motile and rod-shaped bacterial strain containing flexirubin-type pigments, designated S31T, was isolated from bank-side soil of the Xixi wetland in Zhejiang province, China. Growth occurred at 10–37 °C (optimum, 32 °C), pH 6–8 (optimum, pH 7) and with 0–2 % (w/v) NaCl (optimum, 1 %). Strain S31T shared highest 16S rRNA gene sequence similarities with Epilithonimonas lactis H1T (96.2 %) and Chryseobacterium molle DW3T (96.4 %). Phylogenetic analysis suggested that strain S31T was a member of the genus Epilithonimonas . The dominant respiratory quinone was MK-6 and the DNA G+C content was 33.3 mol%. The major fatty acids were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) and anteiso-C15 : 0. The major polar lipids of strain S31T were phosphatidylethanolamine, three unidentified aminolipids and four unidentified polar lipids. Based on its phenotypic and chemotaxonomic characteristics and phylogenetic data, strain S31T represents a novel species of the genus Epilithonimonas , for which the name Epilithonimonas xixisoli sp. nov. (type strain S31T = CGMCC 1.12802T = NBRC 110387T) is proposed.
