Abstract
A yellow-pigmented, Gram-negative, non-flagellated, rod-shaped bacterial strain, designated M0322T, was isolated from a mudstone core sample of the Mohe Basin, China. Growth of strain M0322T was observed at 15–40 °C (optimum, 30 °C), at pH 5.0–10.0, (optimum, pH 6.0–7.0) and in the presence 0–4 % NaCl (optimum, 0 %). Phylogenetic analyses of 16S rRNA gene sequences revealed that strain M0322T formed a distinct phyletic lineage with the members of the genus Altererythrobacter and is closely related to Altererythrobacter aestuarii JCM 16339T (96.1 %) and Altererythrobacter namhicola JCM 16345T (95.7 %). The only isoprenoid quinone was identified as ubiquinone 10 (Q-10), major polar lipids were determined to be phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, one unidentified glycolipid and three unidentified phospholipids, while major cellular fatty acids were summed feature 8 (C18:1 ω6c and/or C18:1 ω7c), summed feature 3 (C16:1 ω6c and/or C16:1 ω7c) and 11-Methyl C18:1 ω7c. The DNA G+C content of strain M0322T was determined to be 64.6 mol%. Based on the results of the polyphasic taxonomic study, strain M0322T is considered to represent a novel species of the genus Altererythrobacter, for which the name Altererythrobacter buctense sp. nov. is proposed. The type strain is M0322T (=CGMCC 1.12871T = JCM 30112T).
