Background:

Nowadays, numerous bacterial strains, genus Bacillus, are used as probiotics to promote the growth of cultivated aquatic organisms, particularly in their larval stages.

Aim.

To conduct a review of the different applications of Bacillus firmus in the industry, with emphasis on their use as a probiotic for aquaculture.

Development:

B. firmus is a widely used beneficial bacterium as a nematicide to protect crops, the bioremediation of contaminated environments, enzyme production, and as a probiotic for aquaculture. Its potentiality for shrimp culture is outstanding for controlling diseases and water quality management in the pond.

Conclusions:

Nevertheless, its specific mechanisms for shrimp culture have not been studied broadly, which is particularly interested in providing all the benefits that this bacterium offers to this economic sector.
