The Psychrobacter genus is a cosmopolitan and diverse group of aerobic, cold-adapted, Gram- negative bacteria exhibiting biotechnological potential for low-temperature applications including bioremediation. Here, we present the draft genome sequence of a bacterium from the Psychrobacter genus isolated from a sediment sample from King George Island, Antarctica (3,490,622 bp; 18 scaffolds; G + C = 42.76%). Using phylogenetic analysis and scanning electron microscopy the bacterium was identified as Psychrobacter glacincola BNF20, making it the first genome sequence reported for this species. P. glacincola BNF20 showed high and moderate tellurite (MIC 2.3 mM) and chromate (MIC 6.0 mM) resistance, respectively. Genome-wide nucleotide identity comparisons revealed that P. glacincola BNF20 is highly similar (>90%) to other uncharacterized Psychrobacter spp. such as JCM18903, JCM18902, and P11F6. Bayesian multi-locus phylogenetic analysis showed that P. glacincola BNF20 belongs to a polyphyletic clade with other bacteria isolated from polar regions. A high number of genes required for metal(loid) resistance were found, including tellurite resistance genetic determinants located in two contigs: Contig LIQB01000002.1 had 5 ter genes, each showing putative promoter sequences (terACDEZ), whereas contig LIQB1000003.2 had a variant of the terZ gene. Finally, investigating the presence and taxonomic distribution of ter genes in the NCBI´s RefSeq bacterial database (5,398 genomes, as January 2017), revealed that 2,623 (48.59%) showed at least one ter gene. At the family level, most (68.7%) harbored one ter gene and 15.6% exhibited five (including P. glacincola BNF20). Overall, our results highlight the diverse nature of the Psychrobacter genus, provide insights into potential mechanisms of metal resistance, and exemplify the benefits of sampling remote locations for prospecting new molecular determinants.


Is this open peer review?

No, peer review is still single-blind and all recommendations are private between the authors and Academic Editor. However, any reviewer has the option to sign their report, and once accepted for publication then that review can be shown publicly - again this is optional.

Will I be guaranteed to review if I volunteer?

No. Volunteering is not a guarantee that you will be asked to review. This is for many reasons. For one, reviewers must have relevant qualifications for any manuscript and void of any conflicts of interest. Additionally, it could be that enough reviewers have accepted an invitation to review already, in which case we would not invite any more.

Why aren't there more manuscripts available?

Manuscripts are shown when authors have opted-in for obtaining reviewers through the reviewer-match service. Additionally, there may already be enough reviewers found through other means, for example, invitations sent by the Academic Editor in charge.

What are the editorial criteria?

Please visit the editorial criteria page for initial guidance. You will also be given additional information if invited to review.
