A Gram-negative, non-motile, non-spore-forming, ovoid-shaped bacterium designated as SWU3(T) was isolated from mountain soil collected at Seoul Women's University, South Korea. Based on 16S rRNA sequence analysis, strain SWU3(T) was found to belong to the genus Altererythrobacter. It shares high sequence similarities with A. dongtanensis JM27(T) (96.6 %), A. epoxidivorans JCS350(T) (96.6 %), and A. troitsensis KMM 6042(T) (96.5 %). Growth was observed between 15 and 37 A degrees C (optimum, 30 A degrees C) with pH of 6-9 (optimum, pH 7.0). It could tolerate 0-2 % (w/v) NaCl. Its predominant quinone was found to be ubiquinone (Q-10). Its major cellular fatty acids were determined to be C-17:1 omega 6c, C-18:1 omega 7c, and summed featured 3 (C-16:1 omega 7c/C-16:1 omega 6c), all of which are similar characteristics to those of species within the genus Altererythrobacter. Its G + C molar content was found to be 58.4 mol%. Phylogenetic evidence, together with phenotypic characteristics showed that strain SWU3(T) represents a new species of the genus Altererythrobacter. The name Altererythrobacter terrae sp. nov. is proposed and the type strain is SWU3(T) (=KEMB 9004-128(T) = JCM 19177(T)).
