Microbial biosurfactants are an attractive and promising class of molecules with the potential to replace oil-derived surfactants for formulation ecofriendly biocompatible products. In this review, we discuss literature findings, mostly reported in last decade, on self-assembly four main classes microbial biosurfactants, i.e., rhamnolipids, mannosylerythritol lipids, sophorolipids, surfactin. All them present composite molecular structures, characterized by different functional groups ionizable moieties a high conformational flexibility. Where possible, formation aggregate morphologies terms biosurfactant structure variation environmental parameters. We highlight how is regulated complex interplay between various intermolecular interactions, including H-bonds steric constraints, besides electrostatic hydrophobic interactions. For reason, show that common theoretical approaches amphiphile self-assembly, such as critical packing parameter, have limitations rationalizing predicting aggregation behaviour.

Sophorolipids, glycolipid biosurfactants derived from microorganisms such as Starmerella bombicola , possess distinctive surface-active and bioactive properties, holding potential applications in cosmetics, pharmaceuticals bioremediation. However, the limited structural variability wild-type sophorolipids restricts their properties applications. To address this, metabolic engineering efforts have allowed to create a portfolio of molecules. In this study, we went one step further by chemically modifying microbially produced sophorosides, an engineered S. bombicola. Twenty-four new sophoroside derivatives were synthesized, including amines with varying alkyl chain lengths (ethyl octadecyl) on nitrogen atom corresponding quaternary ammonium salts. Additionally, six different hydrogenated achieve fully saturated lipid tails. These derivatives, along glycolipids three benchmark (di-rhamnolipids, polyglucosides, cocamidopropyl betaine), assessed for antimicrobial activity against bacteria ( Bacillus subtilis, Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Pseudomonas aeruginosa ) yeast Candida albicans ). Results indicated that glycolipids, bola acidic glucolipids exhibit selective test organisms. Conversely, lactonic sophorolipids, salts display broad activity.

Significant research has been conducted to minimise environmental impacts and promote the sustainable use of resources raw materials. Microbial surfactants are an example advanced materials obtained from production processes. In present study, a biosurfactant was produced by yeast Starmerella bombicola ATCC 22214 grown in previously selected low-cost mineral medium containing 10% sucrose, 1.2% canola oil, 0.5% corn steep liquor.
