• Abstract: Biosurfactants with antimicrobial, antifungal and antiviral properties have been enhancing the potential application in formulations used in several purposes as well as to cosmetics, vaccines, pharmaceuticals, food and even veterinary products. Nevertheless, the high cost of production and purification has been a limitation to the application of biosurfactants. The cost reduction can be obtained using industrial residues once it is able to provide the nutrients necessary and sufficient for high productivity of the biotechnological product. Dairy residues are a byproduct rich in proteins, vitamins, fat, lactose and salts, containing therefore, essential nutrients to cellular growth. Experiments were performed to obtain the ideal lactose concentration of dairy residue culture medium for the best production of the antimicrobial biosurfactant from Bacillus atrophaeus ATCC9372. Results indicated that the presence of lower lactose concentration (2.5 g L−1) improve the cell and biosurfactant productivity (Px and PB), respectively, 0.092 gX L−1 h−1 and 4.67 mgB L−1 h−1. In addition, the extraction utilizing ammonium sulfate 5.0 M and t-butanol results in a biosurfactant thin layer that can be re-suspended in buffer and presents an efficient antimicrobial activity from Gram-positive and Gram-negative microorganisms as well as good stability at moderate pH and temperature.
