We isolated 16 antibiotic-producing bacterial strains throughout the central Arctic Ocean, including seven
<jats:named-content content-type="genus-species">Arthrobacter</jats:named-content>
spp. with almost identical 16S rRNA gene sequences. These strains were numerically rare, as revealed using 454 pyrosequencing libraries.
<jats:named-content content-type="genus-species">Arthrobacter</jats:named-content>
spp. produced arthrobacilins A to C under different culture conditions, but other, unidentified compounds likely contributed to their antibiotic activity.
