van de Schootbrugge, B. (author), Houben, A.J.P. (author), Ercan, F.E.Z. (author), Verreussel, R. (author), Kerstholt, S. (author), Janssen, N.M.M. (author), Nikitenko, B. (author), Suan, G. (author)The Toarcian Oceanic Anoxic Event (T-OAE, c. 182 Ma) represents a major perturbation of the carbon cycle marked by widespread black shale deposition. Consequently, the onset of the T-OAE has been linked to the combined effects of global warming, high productivity, basin restriction and salinity stratification. However, the processes that led to...article 2019

Berg, S. (author), Leng, M.J. (author), Kendrick, C.P. (author), Cremer, H. (author), Wagner, B. (author)Organic carbon occluded in diatom silica is assumed to be protected from degradation in the sediment. δ13C from diatom carbon (δ13C(diatom)) therefore potentially provides a signal of conditions during diatom growth. However, there have been few studies based on δ13C(diatom). Numerous variables can influence δ13C of organic matter in the marine...article 2013

(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

Centraal Instituut voor Voedingsonderzoek TNO (author), Pierik, A.J. (author), Roseboom, W. (author), Happe, R.P. (author), Bagley, K.A. (author), Albracht, S.P.J. (author)Infrared-spectroscopic studies on the [NiFe]-hydrogenase of Chromatium vinosum-enriched in 15N or 13C, as well as chemical analyses, show that this enzyme contains three non-exchangeable, intrinsic, diatomic molecules as ligands to the active site, one carbon monoxide molecule and two cyanide groups. The results form an explanation for the three...article 1999
