Biosurfactants are amphiphilic compounds produced, essentially, by microbial cells. The production/applications of biosurfactants are aligned to the green chemistry concept, which includes antimicrobial (bacteria, fungal, mycoplasma, etc), microbial enhanced oil recovery (MEOR), and emulsification, among others [1]. Surfactin, one of the most well-know biosurfactants, was first found in 1968 by Arima, Kakinuma e Tamura [2]. Currently, there are a few surfactin manufacturers as Lipofabrik and Sigma Aldrich that use mineral salt media for surfactin production. Regarding surfactin production, the culture medium represents ≈ 30% total production cost. Thus, some agro-industrial residues have been investigated as alternative culture medium such as olive mill waste, brewery wastewaters, sugarcane and beet molasses, whey, cassava wastewater, etc [3]. In this sense, the cassava processing industry generates ≈ 300 liters of cassava wastewater/ton of cassava, residue which currently has not industrial application. Cassava wastewater contains high minerals (potassium, calcium, magnesium, etc), carbon and nitrogen concentrations, which allow a good microbial growth: bacteria, fungi and yeasts.
