Therefore, this study aimed to: isolate and identify bacteria of the genus Bacillus sp. coming from the super-intensive
culture system with microbial flakes of L. vannamei; and evaluate its probiotic potential regarding the water quality and the performance and immunological parameters with the same species. of inhibitory compounds and other possible effects produced by different strains such as enzymes, organic acids, bacteriocins and other compounds possibly bene ficial for maintaining water quality and animal
health.
