  • Ammonia-oxidizing archaea possess a wide range of cellular ammonia affinities 
    Jung, M.-Y.; Sedlacek, C.J.; Kits, K.D.; Mueller, A.J.; Rhee, S.-K.; Hink, L.; Nicol, G.W.; Bayer, B.; Lehtovirta-Morley, L.; Wright, C.; de la Torre, J.R.; Herbold, C.W.; Pjevac, P.; Daims, H.; Wagner, M. (Basingstoke : Nature Publishing Group, 2022)
    Nitrification, the oxidation of ammonia to nitrate, is an essential process in the biogeochemical nitrogen cycle. The first step of nitrification, ammonia oxidation, is performed by three, often co-occurring guilds of ...
  • Fusarochromene, a novel tryptophan-derived metabolite from: Fusarium sacchari 
    Marshall, James W.; de Mattos-Shipley, Kate M. J.; Ghannam, Iman A. Y.; Munawar, Asifa; Killen, Jonathan C.; Lazarus, Colin M.; Cox, Russell J.; Willis, Christine L.; Simpson, Thomas J. (Cambridge : Royal Society of Chemistry, 2020)
    Fusarochromene isolated from the plant pathogenic fungus, Fusarium sacchari is closely related to a group of mycotoxins including fusarochromanone previously isolated from various Fusaria spp. Despite their assumed polyketide ...
  • LDL Susceptibility to copper-induced oxidation after administration of a single dose of free or esterified beta-cryptoxanthin 
    Wolters, Maike; Hahn, Andreas (Basel : S. Karger AG, 2004)
    Background: The oxidative modification of LDL is believed to be an initial step in atherosclerosis. Thus, antioxidative substances such as carotenoids may have a role in the prevention of coronary heart disease. We examined ...
  • Light intensity dependence of the kinetics of the photocatalytic oxidation of nitrogen(ii) oxide at the surface of TiO2 
    Dillert, Ralf; Engel, Astrid; Große, Julia; Lindner, Patrick; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2013)
    Air pollution by nitrogen oxides represents a serious environmental problem in urban areas where numerous sources of these pollutants are concentrated. One approach to reduce the concentration of these air pollutants is ...
  • Oxygenated bisabolane fucosides from Carthamus lanatus L. 
    Mikhova, Bozhanka; Duddeck, Helmut; Taskova, Rilka M.; Mitova, Maya; Alipieva, Kalina (Berlin : De Gruyter, 2004)
    The aerial parts of Carthamus lanatus (Asteraceae) afforded four new oxygenated bisabolane fucosides, 10-hydroperoxy-bisabola-2,11-diene 7-O-β-D-fucopyranoside, 11-hydroperoxy-bisabola-2,9-diene 7-O-β-D-fucopyranoside, ...
  • Regio- and stereoselective fungal oxyfunctionalisation of limonenes 
    Kaspera, Rüdiger; Krings, Ulrich; Pescheck, Michael; Sell, Dieter; Schrader, Jens; Berger, Ralf Günter (Berlin : De Gruyter, 2005)
    Selective transformations of limonene by asco- and basidiomycetes were investigated. On the shake flask scale, Penicillium citrinum hydrated R-(+)-limonene to α-terpineol [83% regioselectivity (rs), more than 80 mg l-1 ...
  • Silicon enhances suberization and lignification in roots of rice (Oryza sativa) 
    Fleck, Alexander T.; Nye, Thandar; Repenning, Cornelia; Stahl, Frank; Zahn, Marc; Schenk, Manfred K. (Oxford : Oxford University Press, 2011)
    The beneficial element silicon (Si) may affect radial oxygen loss (ROL) of rice roots depending on suberization of the exodermis and lignification of sclerenchyma. Thus, the effect of Si nutrition on the oxidation power ...
  • Traveling interface modulations in the NH 3 + O 2 reaction on a Rh(110) surface 
    Rafti, M.; Uecker, H.; Lovis, F.; Krupennikova, V.; Imbihl, R. (Cambridge : Royal Society of Chemistry, 2012)
    A new type of traveling interface modulation has been observed in the NH 3 + O 2 reaction on a Rh(110) surface. A model is set up which reproduces the effect, which is attributed to diffusional mixing of two spatially ...
  • Two alanine aminotranferases link mitochondrial glycolate oxidation to the major photorespiratory pathway in Arabidopsis and rice 
    Niessen, Markus; Krause, Katrin; Horst, Ina; Staebler, Norma; Klaus, Stephanie; Gaertner, Stefanie; Kebeish, Rashad; Araujo, Wagner L.; Fernie, Alisdair R.; Peterhansel, Christoph (Oxford : Oxford University Press, 2012)
    The major photorespiratory pathway in higher plants is distributed over chloroplasts, mitochondria, and peroxisomes. In this pathway, glycolate oxidation takes place in peroxisomes. It was previously suggested that a ...
  • UV/Vis light induced degradation of oxytetracycline hydrochloride mediated by Co-TiO2 nanoparticles 
    Akel, Soukaina; Boughaled, Redouan; Dillert, Ralf; Azzouzi, Mohamed El; Bahnemann, Detlef W. (Basel : MDPI AG, 2020)
    Pharmaceuticals, especially antibiotics, constitute an important group of aquatic contaminants given their environmental impact. Specifically, tetracycline antibiotics (TCs) are produced in great amounts for the treatment ...
