Green Synthesis of Biosurfactants: Challenges and Applications

Biosurfactants, a group of surface-active molecules or polymers produced by microorganisms or prepared by green synthesis using green polymers or green starting materials, have emerged as promising sustainable alternatives to synthetic surfactants. Due to their unique properties including stability, biodegradability, scalability and good performance, biosurfactants were explored for different industrial applications including environmental remediation, food, pharmaceuticals and oil recovery. This chapter provides a comprehensive overview of biosurfactants, highlighting their importance, synthesis, applications, and potential for large-scale production. It underscores their potential as eco-friendly and sustainable alternatives to synthetic surfactants, paving the way for a greener future.
