Background: This is a novel work that includes the use of a biosurfactant extract obtained from corn milling industry (named BS-CSW), with antimicrobial activity, as ingredient in formulations to treat acne vulgaris.
Methodology: With this purpose, it was established an incomplete experimental design with 3 independent variables, based on the concentration of non-nano zinc oxide (ZnO) (0-2%), BS-CSW (0-5%) and salicylic acid (0-2%).
Results: This design allowed to obtain a theoretical model that calculates the inhibitory effect on (also named ) for any formulation carried with the ingredients appointed before. It was observed a clear synergetic effect on the inhibition of between ZnO and BS-CSW, in absence of salicylic acid. This fact allowed to reduce the concentration of ZnO, giving more ecofriendly and biocompatible formulations.
Conclusions: It was observed that the biosurfactant extract, in formulations with intermediate concentration of ZnO (1%), possess an inhibitory effect on considerably higher than ZnO alone and similar to ZnO (1%) with salicylic acid (1%). This fact demonstrates the enormous potential of this bioactive extract in antiacne formulations.

Introduction: Biosurfactants are naturally occurring compounds with various ap-plications, biodegradable, non-toxic, and effective in different conditions. This study fo-cuses on the extraction and evaluation of biosurfactants produced by five strains of lactic acid bacteria [LAB] for their potential to inhibit biofilm formation and adhesion by Strep-tococcus mutans.
Methods: The strains of LAB-producing biosurfactants such as Lactobacillus salivarius, L.

This study investigates the removal of ibuprofen and diclofenac from aqueous media via a fully pressurized dissolved air flotation system, enhanced by fenugreek-derived saponin, a plant-based biosurfactant. The use of fenugreek saponin in flotation processes distinguishes this work from previous studies as it offers an ecofriendly and efficient alternative to chemical surfactants. The biosurfactant's surface-active properties were confirmed through FT-IR, UV-vis spectroscopy identified key functional groups and structural characteristics of the saponin, NMR provided molecular insights into its bioactive components, and surface tension analyses demonstrated its ability to reduce interfacial tension, indicating effective surfactant behavior.

The micellization properties of rhamnolipids (RLs) in extreme electrolyte concentrations and temperatures have gained considerable attention due to their broad industrial applications. In this study, the aggregation behavior, specifically the micellization pattern (critical micelle concentration (CMC)) of RLs produced from a newly isolated thermophilic strain of from a harsh environment of an oil field, was investigated by a spectrophotometric method at various temperatures (293-393 K) and electrolyte concentrations (NaCl: 2-20%). The result indicated that the values (0.
