Serratia rubidaea SNAU02 (S. rubidaea SNAU02), a promising microbial strain, has been explored for its capability to produce biosurfactants using cashew apple bagasse as a sustainable carbon source. This study investigates the biotechnological potential of S. rubidaea SNAU02 in the context of environmental sustainability. Cashew apple bagasse, an agro-industrial waste, serves as an inexpensive and renewable substrate for biosurfactant production, contributing to waste valorization and reducing environmental impact. The biosurfactant produced by S. rubidaea SNAU02 demonstrates multifaceted applications, including enhanced oil recovery, bioremediation, and detergent formulation. The isolation and characterization of the biosurfactant reveal its stability under a range of environmental conditions, suggesting its potential for diverse industrial applications. The study also assesses the biocompatibility and ecotoxicity of the biosurfactant, emphasizing its eco-friendly nature. Furthermore, production process optimization and scale-up strategies are explored to enhance the economic viability of biosurfactant production. The findings of this research underscore the significance of integrating microbial biotechnology with waste utilization, offering a sustainable solution for environmental challenges. S. rubidaea SNAU02-mediated biosurfactant production from cashew apple bagasse emerges as a promising biotechnological strategy that aligns with the principles of environmental sustainability, contributing to the development of green and eco-friendly technologies. •Biosurfactant production from cashew apple bagasse has unveiled a promising biotechnological strategy.•Serratia rubidaea SNAU02 demonstrates versatile applications, spanning enhanced oil recovery, bioremediation.•This study contributes to the economic viability of biosurfactant production.•This research underscores the importance of coupling microbial biotechnology with the utilization of agro-industrial waste.
