Bioconversion of agro-industrial by-products in rhamnolipids toward applications in enhanced oil recovery and bioremediation.
In this work, biosurfactant production by a Pseudomonas aeruginosa strain was optimized using low-cost substrates. The highest biosurfactant production (3.2 g/l) was obtained using a culture mediumExpand
Photodegradation of psychiatric pharmaceuticals in aquatic environments--kinetics and photodegradation products.
Benzodiazepines are widely consumed psychiatric pharmaceuticals which are frequently detected in the environment. The environmental persistence and fate of these pharmaceuticals as well as theirExpand
Characterization of phenolic components in polar extracts of Eucalyptus globulus Labill. bark by high-performance liquid chromatography-mass spectrometry.
High-performance liquid chromatography-electrospray ionization mass spectrometry (HPLC-ESI-MS) and tandem mass spectrometry (MS(n)) were used to investigate the phenolic constituents in methanol,Expand
Phenolic characterization of Northeast Portuguese propolis: usual and unusual compounds
In this study, an ethanolic extract from Portuguese propolis was prepared, fractionated by high-performance liquid chromatography, and the identification of the phenolic compounds was done byExpand
Phenolic profiling of Portuguese propolis by LC-MS spectrometry: uncommon propolis rich in flavonoid glycosides.
INTRODUCTION Propolis is a chemically complex resinous substance collected by honeybees (Apis mellifera) from tree buds, comprising plant exudates, secreted substances from bee metabolism, pollen andExpand
Coffee melanoidins: structures, mechanisms of formation and potential health impacts.
During the roasting process, coffee bean components undergo structural changes leading to the formation of melanoidins, which are defined as high molecular weight nitrogenous and brown-coloredExpand
Human plasma stability during handling and storage: impact on NMR metabolomics.
This work contributes to fill in some existing gaps in the knowledge of human plasma degradability during handling and storage, a paramount issue in Nuclear Magnetic Resonance (NMR) metabolomics.Expand
Identification of oxidation products and free radicals of tryptophan by mass spectrometry
New oxidation products and free radicals derived from tryptophan (Trp) oxidation under Fenton reaction conditions were identified using mass spectrometry. After the oxidation of tryptophan usingExpand
Phenolic composition and antioxidant activity of Eucalyptus grandis, E. urograndis (E. grandis × E. urophylla) and E. maidenii bark extracts
Abstract The phenolic composition of Eucalyptus grandis , Eucalyptus urograndis ( E. grandis  ×  E. urophylla ) and Eucalyptus maidenii bark is reported for the first time. High performance liquidExpand
Binding of epigallocatechin‐3‐gallate to transthyretin modulates its amyloidogenicity
MINT‐7294529: TTR (uniprotkb:P02766) and TTR (uniprotkb:P02766) bind (MI:0407) by comigration in non‐denaturing gel electrophoresis (MI:0404)
