Abstract Biodegradation of pollutants is one the most economical methods for their removal and usually accompanied by no production toxic by‐products. In general, this approach favored over others because it offers reduced expenses potential complete mineralization. order to enhance viability longevity bioremediation agents within polluted areas, becomes necessary immobilize cells. Cell immobilization refers procedure confining intact cells specific areas a device or material, without compromising essential biological functions. A wide variety carriers approaches have been used restriction various Immobilization techniques, such as microencapsulation, opened up new possibilities in biotechnology facilitating development artificial organs, cell therapies drug delivery systems. Researchers found promising outcomes applications through microorganisms. This enhances stability, reusability catalytic efficiency, making valuable strategy biocatalysis, other biotechnological processes. Notably, use immobilized microorganisms has led significant improvements pollutants, with some studies achieving 100% efficiency. When comparing degradation between free same time period, results demonstrated that achieved efficiency >21% more than microbial consortia. The primary objective review give an overview key scientific aspects related using cells, particular focus on techniques entrap © 2024 Society Chemical Industry (SCI).

Surfactants are a diverse group of compounds that widely used in range industrial, commercial and household applications. They amphiphilic molecules contain both hydrophilic hydrophobic groups, which allow them to interact with water oil. have number important properties, including the ability reduce surface tension, emulsify liquids solubilise compounds. These properties make valuable applications, detergents (hygiene products), cosmetics, pharmaceuticals agricultural products. However, widespread use surfactants has also raised concerns about their environmental impacts. This review provides an overview applications surfactants, as well impacts, different types uses current understanding fate impacts interactions aquatic organisms, microbial communities natural ecosystems. Finally, ths study discusses strategies for minimising development biodegradable environmentally friendly surfactants.
