Pseudoalteromonas atlantica is a motile, biofilm-forming, Gram-negative chemoorganotroph that is found in oceans worldwide. It was first isolated in association with marine algae and named Pseudomonas atlantica, but has now been assigned to a new genus, Pseudoalteromonas. P.atlantica is found associated with marine eukaryotic hosts (seaweed, crab) as well as in the water column, and produces a variety of biologically active extracellular compounds. The extracellular compounds identified from P.atlantica include enzymes that hydrolyze agar, alginate, and carrageenan, acidic extracellular polysaccharide (EPS), and proteases. It was shown to be a primary biofilm-forming bacteria, attaching to sterile slides and producing voluminous amounts of EPS. Following biofilm formation by P.atlantica , stalked and/or filamentous bacteria with more limited nutrient utilization capabilities attached to the surface, and these organisms were followed by diatoms, microalgae, and sessile protozoa. These results suggest that P. atlantica colonizes solid surfaces quickly, utilizing substrates that are processed for uptake by its secreted agarases, proteases, etc., and then forms biofilms in which the EPS concentrates nutrients and provides substrates for other marine microorganisms.
