Interpretive Summary: Pseudoalteromonas piscicida are commonly found marine bacteria that inhibit the growth of a variety of bacteria, especially Vibrio vulnificus. Vibrio vulnificus is the principle cause of shellfish-related bacterial mortalities among U.S. shellfish consumers. In this paper we describe the complete DNA sequencing of two strains of P. piscicida, DE1-A and DE2-A. Several enzymes were identified, which may account for the strong inhibition of these strains toward Vibrio vulnificus.

Technical Abstract: Highly vesiculated Pseudoalteromonas piscicida strains DE1-A and DE2-A were isolated from seawater and show bactericidal properties toward Vibrio vulnificus and other Gram-positive and negative bacteria. Here, we report the complete genome sequences of both P. piscicida strains and identify proteolytic enzymes potentially involved in their antibacterial properties.
