Surfactants are a group of amphiphilic molecules (i.e., having both hydrophobic and hydrophilic domains) that are a vital part of nearly every contemporary industrial process such as in agriculture, medicine, personal care, food, and petroleum. In general surfactants can be derived from (i) petroleum-based sources or (ii) microbial/plant origins. Petroleum-based surfactants are obvious results from petroleum products, which lead to petroleum pollution and thus pose severe problems to the environment leading to various ecological damages. Thus, newer techniques have been suggested for deriving surfactant molecules and maintaining environmental sustainability. Biosurfactants are surfactants of microbial or plant origins and offer much added advantages such as high biodegradability, lesser toxicity, ease of raw material availability, and easy applicability. Thus, they are also termed "green surfactants". In this regard, this review focused on the advantages of biosurfactants over the synthetic surfactants produced from petroleum-based products along with their potential applications in different industries. We also provided their market aspects and future directions that can be considered with selections of biosurfactants. This would open up new avenues for surfactant research by overcoming the existing bottlenecks in this field.

This review paper aims to explore the multifaceted roles and applications of microbial surfactants, also known as biosurfactants. These amphiphilic compounds, synthesized by various microorganisms such as Acinetobacter sp., Bacillus sp., Candida antarctica, and Pseudomonas aeruginosa, exhibit both hydrophobic and hydrophilic properties. Through lowering surface tension and interfacial tension, biosurfactants facilitate fluid phase aggregation, imparting organisms with unique physiological and ecological advantages. The synthesis of biosurfactants in bacteria not only contributes to antimicrobial activity but also enhances substrate availability for cellular absorption, particularly in challenging environmental conditions. Categorized based on molecular weight and chemical composition, biosurfactants offer numerous benefits including biodegradability, reduced toxicity, and versatile applications in agriculture, detergent production, biopesticides, and microbial oil enhancement processes. This review synthesizes current knowledge on microbial surfactants, elucidating their diverse roles and promising applications across various industries.
