Biodegradation of Plastics: The role of biosurfactant-producing bacteria in environmental remediation

Abstract

The growing environmental concern regarding plastic pollution has prompted the exploration of sustainable solutions, with biodegradation emerging as a promising approach.Plastics, particularly polyethylene and polypropylene, are highly resistant to degradation due to their stable chemical structures.However, recent studies suggest that certain bacteria, particularly those capable of producing biosurfactants, can play a significant role in plastic degradation.Biosurfactants are surfaceactive compounds produced by microorganisms that enhance the bioavailability of hydrophobic substrates, facilitating the breakdown of complex organic materials like plastics.This review explores the mechanisms through which biosurfactant-producing bacteria degrade plastics, focusing on their ability to break down polymer chains and convert plastic materials into simpler, less harmful substances.The production of biosurfactants not only aids in plastic degradation but also reduces the environmental impact of plastic waste by promoting bioremediation in contaminated ecosystems.Furthermore, biosurfactant production can be optimized for large-scale applications, offering a costeffective and eco-friendly alternative to conventional plastic waste management techniques.This paper highlights the potential of biosurfactant-producing bacteria in environmental remediation, underscoring their role in reducing plastic pollution and fostering sustainable solutions to one of the most pressing environmental challenges of the modern era.
