(Elsevier, 2018-01)
A biotechnological process that combines the treatment of Citrus processing waste to extract a high-valuable biomolecule, neohesperidin (NEO), and its further modification by biocatalysis to enhance the lipophilicity of ...
The antioxidant activity of a prenyl flavonoid alters its antifungal toxicity on Candida albicans biofilms
(Pergamon-Elsevier Science Ltd, 2018-04)
The antioxidant effect of 8PP, a prenylflavonoid from Dalea elegans on Candida albicans biofilms, was investigated. We previously reported that sensitive (SCa) and resistant C. albicans (RCa) biofilms were strongly inhibited ...

Appetitive behavior of the honey bee Apis mellifera in response to phenolic compounds naturally found in nectars
(Company of Biologists, 2019)
The honey bee is the most frequently used species in pollination services for diverse crops. In onion crops (Allium cepa L.), however, bees avoid visiting certain varieties, being attracted differently to male sterile (MS) ...
Identification of a Bifunctional Maize C- and O-Glucosyltransferase
(American Society For Biochemistry And Molecular Biology, 2013-10)
Flavonoids accumulate in plant vacuoles usually as O-glycosylated derivatives, but several species can also synthesize flavonoid C-glycosides. Recently, we demonstrated that a flavanone 2-hydroxylase (ZmF2H1, CYP93G5) ...
