“…[1] BS are produced mainly by bacteria (e.g. Bacillus and Pseudomonas genera) and yeasts, such as Candida or Yarrowia [2][3][4][5] BS are a broad group of molecules that include lipopeptides (LP), lipoproteins, glycopeptides, phospholipids, etc. LP are comprised of a hydrophobic tail, which is usually a fatty acid, linked to a hydrophilic head between 4 and 12 amino acids.…”

“…Due to their chemical structure and biological and physiochemical properties, LPs are a particularly promising class of BS. [2,3,6,7] LPs exhibit activities that make these molecules potentially useful in industry, environmental protection and medical fields. Previous research has highlighted their potential use as bioemulsifiers, heavy metal-binding compounds, antibiotics, antifungals and antitumor agents.…”

“…Potential applications of LP/BS has been the subject of a number of thorough reviews and research publications. [2,3,[8][9][10][11][12] The broad spectrum of properties attributed to LP can be credited to their modularity, which results in a variety of possible structures. A change in a single amino acid within the molecule can cause an activity modification.…”

Lipopeptide biosurfactants are surface active biomolecules that are produced by a variety of microorganisms. Microbial lipopeptides have gained the interest of microbiologists, chemists and biochemists for their high biodiversity as well as efficient action, low toxicity and good biodegradability in comparison to synthetic counterparts. In this report, we review methods for the production, isolation and screening, purification and structural characterization of microbial lipopeptides. Several techniques are currently available for each step, and we describe the most commonly utilized and recently developed techniques in this review. Investigations on lipopeptide biosurfactants in natural products require efficient isolation techniques for the characterization and evaluation of chemical and biological properties. A combination of chromatographic and spectroscopic techniques offer opportunities for a better characterization of lipopeptide structures, which in turn can lead to the application of lipopeptides in food, pharmaceutical, cosmetics, agricultural and bioremediation industries.

“…The addition of surfactants in a washing procedure will make the liquid spread more easily and lower the interfacial tension between the two liquids or between a liquid and a solid. In addition, they may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants (6,37). Surfactants contain both a hydrophilic group and a hydrophobic group, which interact with the substance they are mixed with in order to alter the surface properties of the water either at the water-and-air interface or at the water-andsolid interface (6,37).…”

Because of these properties, surfactants allow the release of tightly bound contaminations such as foodborne pathogens from the surface, which leads us to hypothesize that surfactants may enhance the removal of food-borne pathogens from fresh produce.…”

Fruits and vegetables are major vehicles for transmission of food-borne enteric viruses since they are easily contaminated at pre-and postharvest stages and they undergo little or no processing. However, commonly used sanitizers are relatively ineffective for removing human norovirus surrogates from fresh produce. In this study, we systematically evaluated the effectiveness of surfactants on removal of a human norovirus surrogate, murine norovirus 1 (MNV-1), from fresh produce. We showed that a panel of surfactants, including sodium dodecyl sulfate (SDS), Nonidet P-40 (NP-40), Triton X-100, and polysorbates, significantly enhanced the removal of viruses from fresh fruits and vegetables. While tap water alone and chlorine solution (200 ppm) gave only <1.2-log reductions in virus titer in all fresh produce, a solution containing 50 ppm of surfactant was able to achieve a 3-log reduction in virus titer in strawberries and an approximately 2-log reduction in virus titer in lettuce, cabbage, and raspberries. Moreover, a reduction of approximately 3 logs was observed in all the tested fresh produce after sanitization with a solution containing a combination of 50 ppm of each surfactant and 200 ppm of chlorine. Taken together, our results demonstrate that the combination of a surfactant with a commonly used sanitizer enhanced the efficiency in removing viruses from fresh produce by approximately 100 times. Since SDS is an FDA-approved food additive and polysorbates are recognized by the FDA as GRAS (generally recognized as safe) products, implementation of this novel sanitization strategy would be a feasible approach for efficient reduction of the virus load in fresh produce.

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]
