Abstract
Aquatic lactic acid bacteria isolated from fish, shellfish and seafood play a very important role in the intestinal flora and can be used as probiotics in aquaculture farming. The aim of this work was to isolate bacteria with high probiotic potential from Artemia sp. collected from the Sidi Bouziene (Relizane) and Bethiou (Oran) saline. Some lactic acid bacteria were tested for their antagonistic power towards indicator strains of the natural environment. The interesting strains were tested for their lactic acid production, their biofilm production, as well as their biosafety (antibiotic resistance test and hemolysis test). The results showed that some lactic acid bacteria had antagonistic activity against a wide spectrum of indicator strains. They showed a good production of lactic acid, and a medium to low production of biofilm.
