Paenibacillus telluris sp. nov., a novel phosphate-solubilizing bacterium isolated from soil

Abstract

A phosphate-solubilizing bacterial strain designated PS38 T was isolated from farm soil. The isolate was a Gram-positive, motile, endospore-forming, rod-shaped bacterium. It grew optimally at 37°C and pH 7.5. The predominant cellular fatty acids were anteiso-C 15:0, anteiso-C 17:0, and iso-C 16:0. The DNA G+C content was 49.5 mol% and the predominant menaquinone was MK-7. Phylogenese analyses based on 16S rRNA gene sequences showed that the strain PS38 T belonged to the genus Paenibacillus and was most closely related to Paenibacillus chibensis JCM 9905 T, P. barengoltzii SAFN-016 T, P. timonensis 2301032 T, and P. motobuensis MC10 T with 96.3%, 96.0%, 95.9%, and 95.5% 16S rRNA gene sequence similarity, respectively. On the basis of morphological, chemotaxonomic, physiological, and phylogenetic properties, strain PS38 T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus telluris sp. nov. is proposed. The type strain is PS38 T (=KCTC 13946 T =CGMCC 1. 10695 T).
