Characterization of Mycobacterium antarcticum sp. nov., a psychrotolerant member of the genus Mycobacterium isolated from Antarctic soil.

ABSTRACT: Most species of the genus Mycobacterium are widely distributed in soil and aquatic environments; however, there is limited understanding of their distribution and adaptation to permanently cold environments. Psychrophilic/psychrotolerant bacteria isolated from cold environments represent an important resource that can be used to understand these aspects. Here, we report representative psychrotolerant mycobacteria strains, designated TUM20985^T, TUM20983, and TUM20984, from Antarctic soils. Phylogenetic analysis using the 16S rRNA gene and average nucleotide identity confirmed that these three strains belong to the same species, and are most closely related to Mycobacterium hodleri JCM 12141^T. These strains are psychrotolerant and grow at 4-25 °C, but not above 30 °C. A
