Pedobacter pollutisoli sp. nov., Isolated from Tetrabromobisphenol A-Contaminated Soil
A Gram-stain negative, strictly aerobic, non-spore forming, non-motile, rod-shaped bacterium, designated TBBPA-24(T), was isolated from tetrabromobisphenol A-contaminated soil in China. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain TBBPA-24(T) was most closely related to Pedobacter nanyangensis Q4(T) (96.5%) and Pedobacter zeaxanthinifaciens' TDMA-5(T) (96.1%). Chemotaxonomic analysis revealed that strain TBBPA-24(T) possessed MK-7 as the major respiratory quinone and lipid, aminolipid, phospholipid, phosphatidylethanolamine, and phosphoaminolipid as the major polar lipid. The major fatty acids were iso-C-15:0 (40.2%), summed feature 3 (C(16:1)6c and/or C(16:1)7c, 25.6%) and iso-C-17:0 3-OH (16.4%). The genomic DNA G+C content of strain TBBPA-24(T) was 43.9mol%. Based on the phylogenetic, phenotypic characteristics, and chemotaxonomic data, strain TBBPA-24(T) is considered a novel species of the genus Pedobacter, for which the name Pedobacter pollutisoli sp. nov. is proposed. The type strain TBBPA-24(T) (=KCTC 62314(T)=CCTCC AB 2017244(T)) is proposed.
