Summary: | This study focused on the low-cost production of biosurfactant by Bacillus subtilis UCP 0999, using cassava wastewater (CWW) and waste frying oil (WFO) as renewable substrates. A 22 full-factorial design (FFD) was employed to investigate the effects of concentrations of agro-industrial wastes in surface tension (ST) and emulsification index (EI24). According to the results, the minimum value of ST (33.2 mN/m) and the maximum value of EI24 (95%) was obtained at central point of the FFD, using 5% CWW and 2% WFO. Statistical analyses demonstrated the significative influence of both substrates in ST and EI24. The biosurfactant showed 2.67 g/L yield and anionic and lipopeptide nature by Zeta potential and Fourier transform infrared (FT-IR) spectroscopy, respectively. In addition, promising applications of biosurfactant as biodispersant and viscosity reducing agent were demonstrated, suggesting its potential use in petroleum industry or bioremediation of hydrophobic pollutants. |

Se empleó un diseño factorial completo 22 para investigar los efectos de las concentraciones de los residuos agroindustriales en la tensión superficial (TS) y el índice de emulsificación (IE24). De acuerdo con los resultados, el valor mínimo de TS (33,2 mN/m) y el valor máximo de EI24 (95%) se obtuvo en el punto central del diseño experimental, utilizando 5% de agua residual de yuca y 2% de aceite de fritura residual. Los análisis estadísticos demostraron la influencia significativa de ambos sustratos en TS y IE24. El biosurfactante mostró un rendimiento de 2.67 g/L y naturaleza aniónica y lipopeptídica por potencial Zeta e espectroscopía de infrarrojo por transformada de Fourier (FT-IR), respectivamente. Además, se demostraron aplicaciones prometedoras del biosurfactante como biodispersante y agente reductor de la viscosidad, lo que sugiere su uso potencial en la industria petrolera o en la biorremediación de contaminantes hidrofóbicos.Este estudo teve como foco a produção de baixo custo de biossurfactante por Bacillus subtilis UCP 0999, utilizando manipueira e óleo residual de fritura como substratos renováveis.
