Zeta potential changes of Saccharomyces cerevisiae during fermentative and respiratory cycles
(Elsevier Science, 2019-02)
Saccharomyces cerevisiae is a type of yeast, widely used in diverse biotechnological food-beverage processes. Although the performance of an industrial fermentation process depends largely on the number of cells, it is ...
Interaction of green silver nanoparticles with model membranes: Possible role in the antibacterial activity
(Elsevier Science, 2018-11)
Silver nanoparticles (AgNPs) constitute a very promising approach for overcoming the emergence of antibiotic resistance bacteria. Although their mode of action could be related with membrane damage, the AgNPs-lipid membrane ...

Measure of Zeta Potential of Titanium Pillared Clays
(Elsevier, 2015-07)
The change of the zeta potential, ζ, with the pH as well as the isoelectric point of a charged particle are electrokinetic properties that characterize it. The TiO2 pillared clays are very interesting materials because of ...

Preliminary characterization of a spray-dried hydrocolloid from a high andean algae (nostoc sphaericum)
(Licensee MDPI, Basel, Switzerland.CH, 2022)
The search for new natural sources of hydrocolloids with stabilizing, thickening, and good
binding capacity, from raw materials that are environmentally friendly and that contribute to the
circular economy is a challenge ...
Chemical composition of Schinus areira essential oil and antimicrobial action against Staphylococcus aureus
(Taylor & Francis Ltd, 2019-10)
The antimicrobial activities of plant extracts have formed the basis of many alternative medicines. In this context, the genus Schinus L. (Anacardiaceae), exhibits many traditional uses in medicine. However, a few studies ...
Filling gaps in the knowledge of melittin on lipid membranes
(Elsevier Science, 2019-01-21)
Melittin (ML) is a small peptide of 26 residues rich in arginine (Arg) and lysine (Lys). Several studies have been done to understand the mechanism of interaction with neutral and negatively charged lipids. However, it is ...
Experimental and computational studies of the effects of free DHA on a model phosphatidylcholine membrane
(Elsevier Ireland, 2018-12)
Docosahexaenoic acid (DHA, 22:6) is a natural active compound that has raised considerable interest due to its several biological effects. In this work, effects of free DHA on the physicochemical properties of dipalmitoy ...
