Abstract

This study aimed to evaluate the biotechnological potential of Lacticaseibacillus paracasei Shirota to produce biosurfactants/bioemulsifiers, lipase, and bacteriocins. The production of biosurfactants/bioemulsifiers was evaluated through a central composite rotational design (CCRD) 2. L. paracasei produced bioemulsifiers using MRS supplemented with 4.8% glycerol and pH 6 or 7. In addition, the culture supernatants of L. paracasei were tested for antioxidant, antidiabetic, and lipolytic activities. The tested supernatants did not exhibit antioxidant activity. On the other hand, they showed inhibitory activity for amyloglucosidase (20.7% and 23.9%) and lipolytic activity (16.12 and 19.00 U/mL). In addition, a CCRD 2 was performed to evaluate the production of bacteriocins. The peptone and lactose concentration variables, as well as pH positively influenced the production of bacteriocins by L. paracasei. In conclusion, L. paracasei is a viable source of antidiabetic metabolites, bacteriocins, bioemulsifiers, and lipase, suggesting that they are promising to be applied in the pharmaceutical, cosmetic, environmental, food, and biomedical industries.
