Pedobacter agrisoli sp. nov., isolated from farmland soil.

ABSTRACT

A Gram-stain-negative, aerobic, non-motile, non-spore-forming and rod-shaped bacterium, designated YHM-9T, was isolated from soil in Yangquan, Shanxi Province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YHM-9T belonged to the genus Pedobacter and shared the highest similarity (97.4 %) to the type strain Pedobacter lignilitoris W-WS13T. Strain YHM-9T exhibited low DNA-DNA relatedness with P. lignilitoris W-WS13T (21.7±1.3 %). The DNA G+C content was 38.9 mol%. The major fatty acids were iso-C15  0, summed feature 3 (C16  1ω7c and/or C16  1ω6c) and iso-C17  0 3-OH. The respiratory quinone was MK-7, the major polyamine was sym-homospermidine and the major polar lipids were phosphatidylethanolamine. Based on the morphological, physiological, biochemical and chemotaxonomic characteristics, strain YHM-9T was recognized as a representative of a novel species within the genus Pedobacter, for which the name Pedobacteragrisoli sp. nov. is proposed. The type strain is YHM-9T (=JCM 32093T=CCTCC AB 2017125T).
