Interpretive Summary:

Technical Abstract: Tilapia is one of the fish most farmed worldwide. Many studies have been carried out over the last few years to select and produce probiotics for this cultured fish. Bacteria from the genera Bacillus, Lactobacillus, and Lactococcus are the most studied with probiotic potential. Among these microorganisms, Lactococcus lactis has outstanding prospect as a probiotic because it has the Generally Recognized as Safe (GRAS) status and has previously been shown to enhance fish growth, survival rates, immune response, and produces beneficial metabolites such as the antibacterial peptide nisin. Nevertheless, it is not sufficient to select a microorganism with great probiotic potential for probiotic commercial development. There is a challenge related to mass-production culture strategies, selecting production variables that positively influence microorganism metabolism. Over the last ten years, the effects of the carbon and nitrogen sources on L. lactis growth have been studied, demonstrating that dietary nitrogen is an essential nutrient for its growth and metabolism, and glucose is the preferred carbon source. Additionally, L. lactis batch production and fed-batch processes have been studied, evaluating the effects of culture temperature and pH on growth. Nevertheless, to have a deeper understanding of production processes, there is a need to determine the effect of the hydrodynamic stress in a bioreactor production and its influence on the probiotic potential after the manufacturing processes. This review aims to explore trends in tilapia aquaculture and parameters essential for optimal scale-up production of probiotic L. lactis for use in aquaculture.
