<i>Methylobacter arcticus</i> sp. nov. isolated from a coal mine biofilm in the high Arctic Svalbard.

ABSTRACT: An aerobic methanotroph was isolated from a biofilm of coal mine Gruve 7 (Svalbard) and designated strain G7^T. Cells of strain G7^T were Gram-stain-negative, pink-pigmented and motile rods. Strain G7^T could grow at pH 6.8 and at temperatures ranging from 4 to 21 °C. The genome size was 4.00 Mb with a (digital) DNA G+C content of 47.7 mol%. Strain G7^T represents a member of the family Methylomonadaceae of the class Gammaproteobacteria. It displayed 94.6-99.7% 16S rRNA gene sequence similarity to the type strains of the genus Methylobacter. Whole-genome comparisons based on average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) confirmed that strain G7^T represents a novel species. It showed 16S rRN
