Screening for lactic acid bacteria (LAB) from fresh shrimp samples (Penaeus vannamei) collected from retail seafood markets in the Tunisian's coast, resulted in the isolation of an Enterococcus strain termed Q1. This strain was selected for its antagonistic activity against pathogenic bacteria such as Listeria monocytogenes, Pseudomonas aeruginosa, Lactococcus garvieae and against fungi (Aspergillus niger and Fusarium equiseti). The Q1 strain was characterised using standard morphological and biochemical tests, growth assays at different temperatures, pH and salinity.

- The study explores the potential of lactic acid bacteria (LAB) as probiotics in aquaculture, offering a safer alternative to antibiotics.
- Isolates from fish were identified as Enterococcus faecium and Lactococcus lactis, with enterococci showing high genetic similarity yet significant diversity.
- Six selected strains demonstrated antibacterial properties against various fish pathogens and produced enterocins A and B, with favorable safety profiles, indicating their promising use as probiotics in aquaculture settings.
