ABSTRACT
Two strains of Gram-staining-negative, rod-shaped bacteria that were motile by gliding, N7d-4(T) and B4a-b5, were isolated during a study of culturable bacteria in soil cultivated with potatoes. These isolates grew at 15-37 °C and at pH 6.5-7.0. The major cellular fatty acids were summed feature 3 (iso-C15ââ0 2-OH and/or C16ââ1ω7c), anteiso-C15ââ0, iso-C15ââ0, iso-C17ââ0 3-OH and iso-C17ââ1ω9c. The major polar lipids were phosphatidyl-N-methylethanolamine and phosphatidylethanolamine. The strains contained d-18ââ0 and d-19ââ0 sphingosines. The DNA G+C contents of strains N7d-4(T) and B4a-b5 were 48.5 and 46.9 mol% (HPLC), respectively. A phylogenetic analysis based on 16S rRNA gene sequences showed that strains N7d-4(T) and B4a-b5 were affiliated with Pedobacter species in the family Sphingobacteriaceae. Strains N7d-4(T) and B4a-b5 shared 99.9â% sequence similarity, and the most closely related Pedobacter type strains were Pedobacter composti TR6-06(T) (96.5 and 96.7â% sequence similarity, respectively), P. oryzae N7(T) (95.4 and 95.6â%) and P. caeni LMG 22862(T) (94.0 and 94.4â%). Phenotypic data and phylogenetic inference clearly distinguished the two isolates from other Pedobacter species. Based on these data, the isolates are considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter luteus sp. nov. is proposed. The type strain is N7d-4(T) (â=âKCTC 22699(T) â=âDSM 22385(T)).
