- Abstract: One of the main constraints of sophorolipid (SL) microbial production is the substrate-associated costs and the lower productivity compared to synthetic surfactants. Nevertheless, SLs have found their potential in multiple markets, including agriculture due to their pesticide and plant-growth-promoting effects. In this sense, this study has aimed in evaluating potential SLs-producing Brazilian native strains of Starmerella bombicola isolated from different biomes, considering their potential of assimilating household residual cooking oil (HCO), which represents a renewable feedstock to aid the issues regarding raw material expenditures. The highest SL production (6.2 g/L) was obtained with S. bombicola Y-6419 which was isolated from the Brazilian Cerrado biome. To analyze the viability of using rice bran aqueous hydrolysate (RBH) as an alternative nutrients source, it was implemented a 22 factorial design, thereby, the concentration of HCO (g/L) and the supplementation of RBH (% v/v) were evaluated as manipulated variables; as a response, SL production (g/L) was quantified. The RBH showed promising utilization as an elicitor of SLs production by S. bombicola and the final SL titer comprised 51 g/L, which represents an augmentation of approximately ninefold compared to the medium without RBH. SLs were characterized for their physical–chemical properties and their chemical structures were confirmed by HPLC–MS, TLC, and FTIR. Thus, the utilization of agroindustry byproducts and a renewable lipophilic carbon source exhibited marked potential in the production of biosurfactants by the native S. bombicola strain which enables a step towards the consolidation of the bioprocess in modern biorefineries.
