Elimination of endocrine disrupting chemicals nonylphenol and bisphenol A and personal care product ingredient triclosan using enzyme preparation from the white rot fungus Coriolopsis polyzona.
Mass spectrometry analysis showed that the enzymatic treatment produced high molecular weight metabolites through a radical polymerization mechanism of NP, BPA and TCS, and these oligomers were produced through the formation of C-C or C-O bonds. Expand
Structure characterization of flavonoid O-diglycosides by positive and negative nano-electrospray ionization ion trap mass spectrometry.
Isomeric flavonoid O-diglycosides were analyzed by positive and negative nano-electrospray ionization (ESI) ion trap mass spectrometry (ITMS) in order to evaluate whether the two most commonExpand
Diterpenes from the leaves of Croton zambesicus.
Two new trachylobane- and one isopimarane-type diterpenoids are isolated from the leaves of Croton zambesicus, together with trans-phytol, beta-sitosterol, alpha-amyrin and stigmasterol. Expand
Carbon Source-Induced Modifications in the Mycolic Acid Content and Cell Wall Permeability of Rhodococcus erythropolis E1
The data show that the cell wall composition of R. erythropolis E1 is influenced by the nutritional regimen and that the most marked effect is a radical change in cell wall permeability. Expand
Key fragmentation patterns of aporphine alkaloids by electrospray ionization with multistage mass spectrometry.
This work reports a detailed study of the fragmentations of aporphine alkaloids by electrospray ionization with multistage mass spectrometry (ESI-MS(n)) in positive mode to yield important information on the structures of a porphines. Expand
Hop as an interesting source of resveratrol for brewers: optimization of the extraction and quantitative study by liquid chromatography/atmospheric pressure chemical ionization tandem mass
On the basis of standard additions applied with the optimized extraction procedure and reverse phase high-performance liquid chromatography-APCI(+)-tandem mass spectrometry, it appears that Tomahawk hop pellets (T90, harvest 2002) contain 0.5 ppm trans-resveratrol. Expand
Phytosterol analysis and characterization in spelt (Triticum aestivum ssp spelta L.) and wheat (T aestivum L.) lipids by LC/APCI-MS
Spelt is still a minor cereal crop, mainly grown in Belgium. It is said to have a better nutritive value than winter wheat. Moreover, interesting functional properties have traditionally beenExpand
Ochratoxin A in domestic and imported beers in Belgium: occurrence and exposure assessment
Beer consumption in Belgium is not likely to contribute to more than a few per cent of the tolerable daily intake (TDI) based on the average consumption, and variability of the OTA contamination in beer with time is shown. Expand
Spelt (Triticum aestivum ssp. spelta) as a source of breadmaking flours and bran naturally enriched in oleic acid and minerals but not phytic acid.
The results of this study show that the Ca/Fe ratio, combined with that of oleate/palmitate, provides a highly discriminating tool to authenticate spelt from wheat flours and to face the growing issue of spelt flour adulteration. Expand
Aerobic Growth of Escherichia coli with 2,4,6-Trinitrotoluene (TNT) as the Sole Nitrogen Source and Evidence of TNT Denitration by Whole Cells and Cell-Free Extracts
Escherichia coli grew aerobically with 2,4,6-trinitrotoluene as sole nitrogen source and caused TNT's partial denitration, and isomers of amino-dimethyl-tetranitrobiphenyl were detected and confirmed with U-15N-labeled TNT. Expand
