Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

Protein hydrolysates in cell culture: Toward multi‐omics characterization

Biotechnology Progress, EarlyView.
While protein hydrolysates are widely used in cell culture applications, they remain undefined and variable products. Multi‐omic characterization evaluating composition and function can transition hydrolysates toward semi‐defined media components.

Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...
