“…As a result, biosurfactants help form a stable biofilm because foreign sources such as microorganisms, hydrophobicity, or electrical charges cannot adhere to it. This property can be observed, for instance, in the surfactant produced by Streptococcus thermophilus , which prevents the accumulation of other thermophilic strains on steel surfaces [ 63 ]. According to a similar study, a biosurfactant produced from Pseudomonas fluorescens prevents Listeria monocytogenes from adhering to steel surfaces [ 64 ].…”

The growing prevalence of resistance to antibiotics potentially makes Escherichia coli and Staphylococcus aureus serious pathogens, necessitating the development of new antimicrobial agents. We extracted crude biosurfactants from a potential probiotic Bacillus spp. to control pathogenic bacteria associated with aerobic vaginal infection. Using nanotechnology formulations, we developed nanoemulsions based on biosurfactants at different concentrations (1% and 3.33%). The results showed that these nanoemulsions were stable, with a weighted index of 0.3, and demonstrated broad-spectrum antibacterial activity against Escherichia coli and Staphylococcus aureus, with MICs ranging between 1.25 and 4 mg/mL. Additionally, the nanoemulsions exhibited interesting antibiofilm effects. All strains became more sensitive to the antibiotics to which they were resistant because of various biosurfactant formulations combined with antibiotics. Lower concentrations of BNE1% and 3.33% were still more efficient than the crude biosurfactants. Our findings demonstrated that the biosurfactant had a strong antibiofilm effect against all tested pathogens. This antibacterial effect can be explained by their ability to alter cell physiology such as cell hydrophobicity and membrane disintegration. Thus, we can conclude that the use of nanotechnology formulations has improved this effect, and the nanoemulsions developed in this study can be used as a potential anti-infectious therapy against multidrug-resistant bacterial strains of clinical origin.

“…This property of biosurfactants helps in formulating a stable biofilm as foreign sources such as micro-organisms, hydrophobicity or electrical charges do not adhere to the surface of biofilm. Some examples of this property include the surfactant produced from Streptococcus thermophilus, that did not allowed the accumulation of other thermophilic strains over a steel surface and prevented it from rusting [71]. In a similar study, a biosurfactant produced from P. fluorescens did not allowed the adhesion of Listeria monocytogens on the surface of a steel [72].…”
