“…This, in turn, can lead to metal mobilization in the water. [91] However, this only works in water that is contaminated. Soil alkalinity is a major factor causing micro-nutrient deficiency in soil and can be mitigated with the help of biosurfactants.…”

“…Moreover, when water is flushed across soil polluted with contaminants, the strong electrostatic interaction between the metal and the surfactant's oppositely charged ions can lead to removing the metal‐surfactant complex from the soil. This, in turn, can lead to metal mobilization in the water [91] . However, this only works in water that is contaminated.…”

Chemical surfactants have raised concerns due to their negative impact on ecosystems, prompting the search for ecofriendly alternatives. Biosurfactants derived from microorganisms offer a promising solution. These biomolecules are less harmful and can replace toxic pesticide surfactants. Biosurfactants have shown potential in agriculture for food digestion, crop protection, soil fertility, disease management, antibacterial properties, and biofilm prevention. They eliminate plantpathogens and improve nutrient availability, supporting plantgrowth. Rhamnolipids, produced by Pseudomonas, reduce surface tension, are used as wetting agents and emulsifiers in agriculture, and antimicrobial and anti-inflammatory medications. Surfactin, a biosurfactant from Bacillus subtilis, improves plant development, controls plant diseases, and fights pathogens and diseases. Candida bombicola yeast produces sopho-rolipids, biodegradable surfactants with antibacterial, anticancer, and anti-inflammatory properties. Pseudozyma yeast produces mannosylerythritol lipids (MELs), which biocontrol fungus and have antibacterial, anticancer, and immunomodulatory activities. Biosurfactants also hold potential in pharmaceuticals, functioning as antioxidants, exhibiting antibacterial and anticancer activities, and acting as drug-delivery systems. However, challenges in biosurfactant production include varying research methods, limited production organism sources, and cost implications for large-scale manufacturing. This minireview explores microbiologically produced biosurfactants, their regulatory parameters, their applications in optimizing soil health and controlling plant infections, and their potential roles in the pharmaceutical sector.* Ability to tolerate high temperatures, * Ability to tolerate variation in pH, * Ability to tolerate saline environment, * Biodegradable character, * Low or non-toxic nature, and * Effective selectivity.Generally, biosurfactants are amphipathic molecules characterized by hydrophobic and hydrophilic components. Generally, the hydrophobic component consists of a very long chain of fatty acids connected. The hydrophilic component comprises positively, negatively, or amphoterically charged ions. In contrast to their chemical analogs, biosurfactants are often categorized by their CMC concentration, low or high molecular weight, the microorganism type that produce biosurfactant, and their mode of action. Low molecular weight biosurfactants are most frequently reported as glycolipids, phospholipids, and [a]

There has been considerable interest in the use of biosurfactants due to the diversity of structures and the possibility of production from a variety of substrates. The potential for industrial applications has been growing, as these natural compounds are tolerant to common processing methods and can compete with synthetic surfactants with regards to the capacity to reduce surface and interfacial tensions as well as stabilise emulsions while offering the advantages of biodegradability and low toxicity. Among biosurfactant-producing microorganisms, some yeasts present no risks of toxicity or pathogenicity, making them ideal for use in food formulations. Indeed, the use of these biomolecules in foods has attracted industrial interest due to their properties as emulsifiers and stabilizers of emulsions. Studies have also demonstrated other valuable properties, such as antioxidant and antimicrobial activity, enabling the aggregation of greater value to products and the avoidance of contamination both during and after processing. All these characteristics allow biosurfactants to be used as additives and versatile ingredients for the processing of foods. The present review discusses the potential application of biosurfactants as emulsifying agents in food formulations, such as salad dressing, bread, cakes, cookies, and ice cream. The antioxidant, antimicrobial and anti-adhesive properties of these biomolecules are also discussed, demonstrating the need for further studies to make the use of the natural compounds viable in this expanding sector.

Hydrophobic surfaces modified by pathogens in agricultural production are one of the main reasons to reduce the utilization of pesticides. Adding surfactants to pesticide solutions is a common method to improve their wetting and spreading properties. In this work, the interaction mechanism between pathogen-modified hydrophobic surfaces and mixtures of surfactants and a pesticide was studied in detail. The interaction mechanism was determined by characterizing the wetting and spreading behaviors of droplets on cucumber powdery mildew leaves at different growth stages. When surfactants were added, droplets on cucumber powdery mildew leaves were in the Wenzel wetting state, the pinning force weakened, the contact line speed accelerated, and the adhesion force increased. We explained the micellar state and aggregation behavior of surfactant molecules in a pesticide solution that was applied to the surface of cucumber powdery mildew leaves. Droplets of solutions containing nonionic surfactants easily formed semibald micelles, binding to the pathogen of powdery mildew, whereas droplets containing cationic surfactants did not do so. Because of the electrostatic interaction between cationic surfactant molecules and powdery mildew pathogens, cationic surfactant molecules did not wet the pathogens very well, so we suggest adding nonionic surfactants rather than cationic surfactants to improve the wetting and spreading of pesticide solutions on cucumber powdery mildew leaves. This study provides new insights into enhancing the wetting and deposition of droplets on pathogen-modified hydrophobic surfaces.
