Bacillus velezensis is a plant growth-promoting bacterium thatcan also inhibit plant pathogens. However, based on its properties,it is emerging as a probiotic in animal feed. This reviewfocuses on the potential characteristics of B. velezensisfor use as a probiotic in the animal feed industry. The reviewwas conducted by collecting recently published articles frompeer-reviewed journals. Google Scholar and PubMed wereused as search engines to access published literature. Basedon the information obtained, the data were divided into threegroups to discuss the (i) probiotic characteristics of B. velezensis,(ii) probiotic potential for fish, and (iii) the future potentialof this species to be developed as a probiotic for theanimal feed industry. Different strains of B. velezensis isolatedfrom different sources were found to have the ability toproduce antimicrobial compounds and have a beneficial effecton the gut microbiota, with the potential to be a candidateprobiotic in the animal feed industry. This review providesvaluable information about the characteristics of B. velezensis,which can provide researchers with a better understandingof the use of this species in the animal feed industry.
