Towards antimicrobial yet bioactive Cu-alginate hydrogels
(IOP Publishing Ltd, Bristol, 2016)
The simplest approach to enhance alginate hydrogel characteristics and functional properties is to replace the calcium in the process of alginate gelation with other metallic ions which are essential for living systems. ...
Novel Approach for Flavonoid Esters Production: Statistically Optimized Enzymatic Synthesis Using Natural Oils and Application in Cosmetics
(Amer Chemical Soc, Washington, 2019)
The present work describes application of natural triglycerides for lipase-catalyzed esterification of structurally diverse flavonoids-esculin, naringin, and phloridzin. Ester mixtures with laurate, linolenate, or linoleate ...
Removal of Anthraquinone Dye by Cross-Linked Enzyme Aggregates From Fresh Horseradish Extract
(Wiley, Hoboken, 2016)
Horseradish roots (Armoracia rusticana) fresh extract was the source of unpurified horseradish peroxidase (HRP) which was used for the immobilization in a form of cross-linked enzyme aggregates (CLEAs). Among three ...
A novel chitosan gels: Supercritical CO2 drying and impregnation with thymol
(Wiley, Hoboken, 2018)
Supercritical carbon dioxide (scCO(2)) technology was used for preparation of functional pH sensitive chitosan-based aerogels characterized with micron size pores and their impregnation with thymol as a natural bioactive ...
Structural and biological evaluation of lignin addition to simple and silver-doped hydroxyapatite thin films synthesized by matrix-assisted pulsed laser evaporation
(Springer, Dordrecht, 2015)
We report on thin film deposition by matrix-assisted pulsed laser evaporation of simple hydroxyapatite (HA) or silver (Ag) doped HA combined with the natural biopolymer organosolv lignin (Lig) (Ag:HA-Lig). Solid cryogenic ...
A high efficacy antimicrobial acrylate based hydrogels with incorporated copper for wound healing application
(Elsevier Science Sa, Lausanne, 2015)
In this study, three series of hydrogels based on 2-hydroxyethyl acrylate and itaconic acid, unloaded, with incorporated copper(II) ions and reduced copper, were successfully prepared, characterized and evaluated as novel ...
Ultrasound Pretreatment as an Useful Tool to Enhance Egg White Protein Hydrolysis: Kinetics, Reaction Model, and Thermodinamics
(Wiley, Hoboken, 2016)
The impact of ultrasound waves generated by probe-type sonicator and ultrasound cleaning bath on egg white protein susceptibility to hydrolysis by alcalase compared to both thermal pretreatment and conventional enzymatic ...
Waste Lard Methanolysis Catalyzed by KOH at Moderate Temperatures
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
The KOH-catalyzed methanolysis of waste lard from piglet roasting in a moderate temperature range was investigated in order to establish the reaction kinetics. For comparison, lard and thermally treated lard were also ...
pH-Sensitive Hydrogels Based on (Meth)Acrylates and Itaconic Acid
(Polymer Soc Korea, Seoul, 2014)
Novel hydrogels based on 2-hydroxyethyl methacrylate (HEMA), itaconic acid (IA) and different poly (alkylene glycol) (meth)acrylates (PAGM) (P(HEMA/IA/PAGM)) were synthesized. We investigated the influence of different ...
Impact of ultrasound on egg white proteins as a pretreatment for functional hydrolysates production
(Springer, New York, 2014)
The objective of this study was to investigate the effects of different ultrasound pretreatment on enzymatic hydrolysis of egg white proteins (EWPs) by Alcalase as well as evaluating some functional and antioxidant properties ...
