(author)In the present double-blind, randomised, parallel intervention study, the effects of the intake of galacto-oligosaccharides (GOS) on the gut microbiota of twelve healthy adult subjects (aged 18-45 years with a normal BMI (18-25 kg/m2)) receiving amoxicillin (AMX) treatment were determined. All the subjects were treated with AMX (375 mg; three...article 2014

(author), Overkleeft, H.S. (author), Overhand, M. (author)This article presents a series of ring-extended gramicidin S derivatives, 9-14, that have four ornithine residues as polar protonated side chains and one modified turn region containing a mono-functionalized cis-δ-oxetane, δ-furanoid, or δ-pyranoid sugar amino acid residue. Of the GS analogs evaluated, we identified compound 7, which contains...article 2012

(author), Venema, K. (author), TNO Kwaliteit van Leven (author)16S rRNA-based stable isotope probing (SIP) and nuclear magnetic resonance (NMR) spectroscopy-based metabolic profiling were used to identify bacteria fermenting glucose under conditions simulating the human intestine. The TIM-2 in vitro model of the human intestine was inoculated with a GI tract microbiota resembling that of the small intestine...article 2007

(author), TNO Industrie (author)Many studies have shown relationships of substratum hydrophobicity, charge or roughness with bacterial adhesion, although bacterial adhesion is governed by interplay of different physico-chemical properties and multiple regression analysis would be more suitable to reveal mechanisms of bacterial adhesion. The formation of a conditioning film of...bookPart 2004

van Nuenen, M.H.M.C. (author), Venema, K. (author), van der Woude, J.C.J. (author), Kuipers, E.J. (author), TNO Voeding (author)The hypothesis was studied that intestinal microbial metabolites play a role in the pathogenesis of inflammatory bowel disease. For that purpose, an in vitro model of the colon was inoculated with fresh feces of six healthy individuals and eight inflammatory bowel disease patients. Samples were taken from the model over time to analyze...article 2004

TNO Milieu, Energie en Procesinnovatie (author), Slenders, J.L.A. (author), Marinussen, M. (author), van der Ben, J. (author), van Vossen, W. (author)At this moment the results of an extensive set of soil and groundwater analyses of about 80 former Dutch landfills are being processed. The study not only has to produce an image of soil and groundwater quality in and around landfills, but also has to lead to a more solid estimate of aftercare measures at the 3800 former landfills in the...conference paper 2000
