Abstract
Biosurfactants have attracted increasing interest due to their biodegradability, low toxicity, and excellent surface-active properties, making them suitable for a wide range of industrial and environmental applications. However, their large-scale production is still limited by the high cost of the fermentation process, particularly the carbon source. This study evaluated the production of biosurfactant by Bacillus subtilis UFPEDA 86 using agro-industrial residues from licuri (Syagrus coronata) and papaya as alternative fermentation substrates. The residues were prepared at a concentration of 250 g.L⁻¹ and used in submerged fermentation conducted at 37 °C and 200 rpm for 24 h. After fermentation, the biosurfactant was recovered by acid precipitation and quantified gravimetrically. Licuri residue yielded 3.95 g.L⁻¹ of crude biosurfactant, whereas papaya residue produced 3.11 g.L⁻¹, demonstrating the superior performance of licuri as a carbon source. Moreover, the biosurfactant production achieved with licuri exceeded values previously reported in the literature for the same bacterial strain. These findings indicate that licuri residue is a promising low-cost substrate for sustainable biosurfactant production, contributing to agro-industrial waste valorization and reducing fermentation costs.
