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

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)).
