“…Bacillus species are one of the most widely used probiotics in tilapia aquaculture. They include Bacillus subtilis (He, Zhang, Xu, Yang, Marubashi, Zhou & Yao ; Iwashita, Nakandakare, Terhune, Wood & Ranzani‐Paiva ), Bacillus pumilus (Aly, Mohamed & John ), Bacillus polyfermenticus (Lukkana, Jantrakajorn & Wongtavatchai ), Bacillus amyloliquefaciens (Reda & Selim ; Selim & Reda ), Bacillus toyoi (Nakandakare, Pieroni Iwashita, Dias, Tachibana, Tavares Ranzani‐Paiva & Romagosa ) and Bacillus cereus (Albuquerque, Marengoni, Mahl, de Moura, Rodriguez‐Rodriguez, Galo & Ribeiro ). These bacteria enhance the growth performance, immune responses and disease resistance of tilapia.…”
