This paper reviews the properties and applications of amphiphilic molecules (surfactants) and biosurfactants, analyzing their roles in improving the environmental pollutant removal processes. Surfactants as a surface-active agent with the ability to reduce surface tension in aqueous and liquid environments are used in various industries, including detergents and cleaners. However, the discharge of these substances into the environment has detrimental consequences such as eutrophication and ecosystem degradation. For this reason, the substitution of chemical surfactants with biosurfactants and biopolymers, which are derived from natural sources and are environmentally safer, has gained attention. In this paper, the combination of biosurfactants with natural biopolymers such as chitosan, alginate and proteins was investigated and their potential for removing surfactants and other pollutants from wastewater is evaluated. The findings indicate that some of these biopolymers, especially chitosan and tannin, are capable of adsorbing high amounts of surfactants. In addition, biosurfactants, with bioactivity and antimicrobial properties, facilitate the optimization of drug delivery and therapeutic processes. In general, this article highlights the importance of biosurfactants and biopolymers in developing sustainable and environmentally friendly methods for wastewater treatment and reducing the destructive effects of pollutants on aquatic ecosystems. and emphasizes the need for further research into innovative technologies to increase the efficiency of these systems in order to optimize cleaning methods and contribute to environmental protection.
