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 Acinetobacter sp., Bacillus Candida antarctica, Pseudomonas aeruginosa, exhibit both hydrophobic hydrophilic properties. Through lowering surface tension interfacial tension, biosurfactants facilitate fluid phase aggregation, imparting organisms with unique physiological ecological advantages. The synthesis in bacteria not only contributes antimicrobial activity but enhances substrate availability for cellular absorption, particularly challenging environmental conditions. Categorized based on molecular weight chemical composition, offer numerous benefits including biodegradability, reduced toxicity, versatile agriculture, detergent production, biopesticides, oil enhancement processes. synthesizes current knowledge elucidating their diverse promising across industries.

This study aims to evaluate rhamnolipid production by immobilized Pseudomonas aeruginosa USM-AR2 cells using waste cooking oil (WCO) as the carbon source. P. were entrapped in polyvinyl alcohol (PVA)-alginate hydrogel beads. The performance of was compared with free shake flasks before cultivation a custom-designed fluidized bed reactor (FBR). A mass 1 g wet PVA-alginate beads successfully recycled 3 times at 200 rpm, producing between 0.66-1.34 L-1 after 120 h. Meanwhile, FBR broth recirculation showed that suitable medium ratio 1:20 an aeration rate 0.5 vvm, 0.77 1.58 rhamnolipid, degrading 8.67 20.93 15 cycles repeated batch cultivation. Entrapped achieved higher production, 1.03-fold during cycle and 1.19-fold 11 FBR, cells. These results show entrapment enables reusability viable maintains stability throughout extended cultivation, increasing cell tolerance perturbations fermentation conditions.
