Recent progress in microbial biosurfactants production strategies: Applications, technological bottlenecks, and future outlook.

[Display omitted] • Recent advances in biosurfactant production strategies and bioreactor scalability. • Genetic engineering and process optimization tools to enhance biosurfactant yield. • Diverse applications of biosurfactants. • Insights into the current commercial biosurfactant producers. • Major challenges and future prospects of biosurfactant production. Biosurfactants are surface-active compounds produced by numerous microorganisms. They have gained significant attention due to their wide applications in food, pharmaceuticals, cosmetics, agriculture, and environmental remediation. The production efficiency and yield of microbial biosurfactants have improved significantly through the development and optimization of different process parameters. This review aims to provide an in-depth analysis of recent trends and developments in microbial biosurfactant production strategies, including submerged, solid-state, and co-culture fermentation. Additionally, review discusses biosurfactants' applications, challenges, and future perspectives. It highlights their advantages over chemical surfactants, emphasizing their biodegradability, low toxicity, and diverse chemical structures. However, the critical challenges in commercializing include high production costs and low yield. Strategies like genetic engineering, process optimization, and downstream processing, have been employed to address these challenges. The review provides insights into current commercial producers and highlights future perspectives such as novel bioprocesses, efficient microbial strains, and exploring their applications in emerging industries.
