(author), Centraal Instituut voor Voedingsonderzoek TNO TNO Voeding (author)The theoretical mathematical models described in this paper are used to evaluate the effects of fungal biomass inactivation kinetics on a non- isothermal tray solid-state fermentation (SSF). The inactivation kinetics, derived from previously reported experiments done under isothermal conditions and using glucosamine content to represent the...article 1999

Vermeiren, L. (author), Devlieghere, F. (author), van Beest, M. (author), de Kruijf, N. (author), Debevere, J. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)Active packaging is one of the innovative food packaging concepts that has been introduced as a response to the continuous changes in current consumer demands and market trends. Major active packaging techniques are concerned with substances that absorb oxygen, ethylene, moisture, carbon dioxide, flavours/odours and those which release carbon...article 1999

(author), TNO Milieu, Energie en Procesinnovatie (author)A set of global greenhouse gas emission inventories has been compiled per source category for the 1990 annual emissions of the direct greenhouse gases CO2, CH4 and N2O, as well as of the indirect greenhouse gases (ozone precursors) CO, NOx and NMVOC, and of SO2. The inventories are available by sector, both on a per country/region basis and on a...article 1999

de Bie, A.T.H.J. (author), van Ommen, B. (author), Bär, A. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)The absorption, disposition, metabolism, and excretion of 14C-labeled γ-cyclodextrin ([14C]γ-CD) was examined in four separate experiments with Wistar rats. In experiment 1, [14C]γ-CD (25 μCi, 600 mg/kg body wt) was administered intravenously to four male and four female conventional rats. In experiment 2, [14C]γ- CD (25 μCi, 1000 mg/kg body wt)...article 1998

(author), Centraal Instituut voor Voedingsonderzoek TNO (author)Metabolic flows, especially those of amino acids, were determined and analyzed at different stages of a batch fermentation for microbial transglutaminase production by Streptoverticillium mobaraense. The method is mainly based on mass balances and measurements of amino acids and other metabolites. The measurements included the consumption rate...article 1998

(author), Centraal Instituut voor Voedingsonderzoek TNO (author)In this paper, correlations between temperature and kinetics of Trichoderma reesei QM9414 growing on wheat bran are described in terms of glucosamine production, oxygen consumption, and carbon dioxide production. Maximum growth temperature (T(max)) being approximately 314 K, is estimated by measuring the radial growth rate on wheat bran. The...article 1998

Rijkeboer, R.C. (author), Havenith, C. (author), Baarbe, H.L. (author), TNO Wegtransportmiddelen (author)Different scenarios have been compared for the future reduction of CO2-emission under real-world driving conditions. A significant shift towards diesel appears hardly to benefit the CO2 but would carry a real NOx penalty. Introduction of DI petrol engines and a shift towards gaseous fuels for s.i. engines would have similar results for CO2,...conference paper 1998

Feron, P.H.M. (author), Jansen, A.E. (author)The use of membrane gas absorption for carbon dioxide production from flue gases is discussed with special reference to the combined supply of heat and carbon dioxide to greenhouses. Novel absorption liquids are introduced which show an improved performance in terms of system stability and mass transfer compared to monoethanolamine when used in...article 1997

Audus, H. (author), Oonk, H. (author), TNO Milieu, Energie en Procesinnovatie (author)The concept of reducing emissions of CO2 to the atmosphere by producing chemicals has been suggested by many people as a potential greenhouse gas mitigation option. The goal of such schemes is either: (i) fixation of CO2 in a chemical compound for a significant time, or, (ii) reduction of emissions by replacing an existing process with an...article 1997

(author), Instituut voor Milieuwetenschappen TNO (author)In an on-going harmonized ESA/NIVR project, performed by Stork Comprimo and TNO-MEP, the removal of the carbon dioxide with membranes is studied. The use of membrane gas absorption for carbon dioxide removal is currently hampered by the fact that the commonly used alkanolamines result in leakage problems when using polyolefin membranes. This...conference paper 1996
