Preservative and Irritant Capacity of Biosurfactants From Different Sources: A Comparative Study

Fungistatic and Fungicidal Capacity of a Biosurfactant Extract Obtained from Corn Steep Water

“…However, at a temperature of 4 • C, the maximum growth inhibition achieved against C. albicans was 17.79%, as shown in Table 2. These results agree with a previous study conducted by Rodríguez-López et al [32], where the biosurfactant extract obtained from CSW after extraction with chloroform did not achieve a fungistatic effect on C. albicans at a temperature of 22 • C. Based on the results obtained in this work, it can be established that the biosurfactant extracted from the CSW with ethyl acetate was much more effective against A. brasiliensis than C. albicans, showing promising results as an antifungal agent against the Aspergillus family. It can be speculated that low temperatures and the presence of the biosurfactant produced a synergic effect on the Based on the results obtained in this work, it can be established that the biosurfactant extracted from the CSW with ethyl acetate was much more effective against A. brasiliensis than C. albicans, showing promising results as an antifungal agent against the Aspergillus family.…”

“…The factorial design also determined the optimal conditions established by the factorial design for both pathogenic strains at room temperature (25 • C), showing that a biosurfactant concentration of 0.99 mg/mL resulted in a maximum inhibition of 57.1% against A. brasiliensis after 11 days of incubation, achieving a fungistatic effect. These results agree with the results obtained by Rodríguez-López et al [32], where a biosurfactant extracted from CSW with chloroform displayed a fungistatic effect on A. brasiliensis at a temperature of 22 • C.…”

Immunomodulatory Role of Microbial Surfactants, with Special Emphasis on Fish

“…Microbial surfactants or biosurfactants (BS) are surface active molecules produced naturally by microorganisms. They comprise both hydrophobic (e.g., hydrocarbon (saturated or unsaturated) chains or fatty acids) and hydrophilic (e.g., acids, peptides, mono-/di-/poly-saccharides) moieties [ 1 ]. Due to their amphipathic nature, BS aggregate at interfaces and reduce the interfacial tension, thus increasing the water solubility of hydrophobic compounds.…”

“…Due to their amphipathic nature, BS aggregate at interfaces and reduce the interfacial tension, thus increasing the water solubility of hydrophobic compounds. They are less toxic, biodegradable, biocompatible, and stable in a wide range of pH, temperatures, or salinity [ 1 , 2 ]. They also exhibit diverse biological activity and can be produced using various renewable resources [ 1 , 3 , 4 , 5 ].…”

“…They are less toxic, biodegradable, biocompatible, and stable in a wide range of pH, temperatures, or salinity [ 1 , 2 ]. They also exhibit diverse biological activity and can be produced using various renewable resources [ 1 , 3 , 4 , 5 ]. Based on molecular weight, BS are divided into two classes: (a) high-molecular weight BS (bioemulsifiers, such as lipoproteins) and (b) low-molecular weight BS (e.g., glycolipids) [ 6 ].…”
