Short Genome CommunicationsComplete genome sequence of Pseudomonas antarctica PAMC 27494, a bacteriocin-producing psychrophile isolated from Antarctica

- Pseudomonas antarctica PAMC 27494, a psychrophilic bacterium isolated from an Antarctic freshwater sample.
- Antimicrobial activity of Pseudomonas antarctica PAMC 27494 was confirmed through a zone of inhibition test at 10 °C and 20 °C.
- The complete genome of Pseudomonas antarctica PAMC 27494, which contains genes encoding microcin B and R-type pyocins, was provided.

Antimicrobial-producing, cold-adapted microorganisms have great potential for biotechnological applications in food, pharmaceutical, and cosmetic industries. Pseudomonas antarctica PAMC 27494, a psychrophile exhibiting antimicrobial activity, was isolated from an Antarctic freshwater sample. Here we report the complete genome of P. antarctica PAMC 27494. The strain contains a gene cluster encoding microcin B which inhibits DNA regulations by targeting the DNA gyrase. PAMC 27494 may produce R-type pyocins and also contains a complete set of proteins for the biosynthesis of adenosylcobalamin and possibly induces plant growth by supplying pyrroloquinoline quionone molecules.
