Planomicrobium soli sp. nov., isolated from soil

A Gram-staining-positive bacterium, designated strain XN13^T, was isolated from a soil sample collected from ALaShan National Geological Park in Inner Mongolia Autonomous Region, China and subjected to a taxonomic study using a polyphasic approach. Strain XN13^T was found to have a range of chemical and morphological properties consistent with its classification in the genus Planomicrobium. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain XN13^T was related to members of the genus Planomicrobium. The closest phylogenetic relatives were Planomicrobium okeanokoites NBRC 12536^T, Planomicrobium koreense JG07^T, Planomicrobium mcmeekinii S23F2^T and Planomicrobium flavidum ISL-41^T with 98.2 %, 97.8 %, 97.8 % and 97.7 % 16S rRNA gene sequence similarity, respectively. The major cellular fatty acids were anteiso-C_{15: 0}, C_{16: 1}ω7c alcohol, iso-C_{14: 0} and C_{16: 1}ω11c. The predominant menaquinones were MK-8 and MK-7. The DNA G+C content was 40.3 mol%. The DNA-DNA relatedness values between strain XN13^T and Planomicrobium okeanokoites KCTC 3672^T, Planomicrobium koreense KCTC 3684^T, P. mcmeekinii CGMCC 1.2724^T, Planomicrobium flavidum KCTC 13261^T, Planomicrobium chinense CGMCC 1.3454^T and Planomicrobium glaciei CGMCC 1.6846^T were 36 %, 30 %, 34 %, 29 %, 30 % and 31 %, respectively. The organism is different from recognized species of the genus Planomicrobium in several phenotypic characteristics. On the basis of phenotypic and genotypic properties, strain XN13^T represents a novel species of the genus Planomicrobium, for which the name Planomicrobium soli sp. nov. is proposed. The type strain is XN13^T (= CGMCC 1.12259^T = KCTC 33047^T).
