A process for extracting biosurfactants from the solid content in corn steep liquor, using a buffered aqueous solution having a pH of 6-8 and a biosurfactant extract obtained using the process of the invention, and the uses in cosmetics, food, pharmaceutical, agrochemical and environmental industries. The obtained biosurfactant has the form of a white powder with foaming capacity and is able to reduce water surface tension by at least 16-20 units.
