摘要

The escalating environmental and public health concerns associated with waste generation have intensified the search for sustainable solutions. One promising approach lies in repurposing waste into valuable products, such as microbial biosurfactants. Biosurfactants derived from industrial waste are substantial because of their sustainability and eco-friendly properties. Microorganisms can produce biosurfactants as secondary metabolites by utilizing waste streams. Besides minimizing waste and providing alternative solutions to synthetic surfactants, biosurfactants are important in bioremediation, food processing, agriculture, and other industrial applications. This paper presents a detailed overview of the global biosurfactant market, reflecting growing consumer demand for eco-friendly alternatives to synthetic surfactants across various industrial sectors. It highlights the valorization of diverse agro-industrial waste as cost-effective and sustainable feedstocks for biosurfactant production. It offers a comparative analysis of different feedstocks, highlighting their efficiency, availability, and impact on yield. Additionally, the paper explores how microorganisms metabolize these substrates and the biosynthetic pathways involved in the production of major biosurfactant classes, providing a mechanistic understanding of microbial conversion processes. To enhance production efficiency, the study explores emerging research trends such as genetic and metabolic engineering, quorum sensing modulation, co-production strategies, and statistical optimization techniques. It further examines the widespread industrial applications of biosurfactants in sectors including oil recovery, detergents, cosmetics, food, pharmaceuticals, nanotechnology, and agriculture. Finally, it addresses key challenges in scaling up biosurfactant production and outlines future prospects for advancing biosurfactant technologies, positioning them as essential components of a circular bioeconomy and sustainable development.
