Interpretive Summary: Pseudoalteromonas piscicida strain DE2-B is a marine bacterium that was isolated from seawater in the Delaware Bay, USA. It produces various enzymes which may account for its inhibitory activity toward a broad array of bacteria including pathogens of fish and humans. We sequenced the entire genome of P. piscicida and entered it into GenBank, making this the first strain to be completely sequenced for this species. The genome contains 5,317,048 bp consisting of two chromosomes of 4,128,210 and 1,188,838 bp. The sequence is available through GenBank and contains a host of genes potentially responsible for the production of digestive enzymes that inhibit and/or kill competing bacteria.

Technical Abstract: Pseudoalteromonas piscicida strain DE2-B is a halophilic bacterium which has broad inhibitory activity toward vibrios and other human and fish pathogens. We report the first closed genome sequence for this species which consists of two chromosomes (4,128,210 and 1,188,838 bp). Annotation revealed multiple genes encoding proteases with potential antibacterial properties.
