    Mechanisms of flocculation with chitosan in Escherichia coli distintegrates: effects of urea and chitosan characteristics1992Inngår i: Colloids and Surfaces, ISSN 0166-6622, E-ISSN 1873-4340, Vol. 69, s. 173-187Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Four different chitosans with different charge densities and different molecular weights were used for investigation of the mechanisms involved in selective flocculation of cell debris particles in E.coli disintegrates. It was found that the main mechanism for flocculation is a "non-equilibrium" bridging process in which a very efficient removal of cell debris particles can be achieved with highly charged chitosans. The high molecular weight (6.5-6.6x105) chitosans produce very large and shear resistant flocs suitable for filtration as well as settling and centrifugation. The low molecular weight (1x105) product forms smaller and more shear sensitive flocs best suited for centrifugation. There are small differences in flocculation dosages depending on molecular weight, but large differences are found with significant changes in charge densities. A decrease in the deacetylation degree from 93 to 39% increased the flocculation dosages by 100 to 150%. A low molecular weight chitosan gave a much broader flocculation region than that of a high molecular weight. Flocculation by addition of urea revealed a hydrogen bonding capacity of chitosan toward cell debris particles which was not involved in chitosan´s interaction with proteins or nucleic acids. The purification of the enzyme -galactosidase could be increased by a factor of 3.7 when using a two step flocculation procedure. The enzyme yield was 82% and the enzyme solution was essentially free of both nucleic acids and cell debris particles.

    Selective flocculation with chitosan in E.Coli disintegrates: effects of ionic strength and multivalent metal ions1993Inngår i: Journal of Dispersion Science and Technology, ISSN 0193-2691, E-ISSN 1532-2351, Vol. 14, s. 269-293Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The effects of ionic strength and multivalent metal ions on the flocculation performance in Escherichia coli cell disintegrates using the polycationic chitosan as a flocculant were investigated. The study showed that ionic strength could be used to optimize the selectivity in flocculation. The best selectivity was obtained at 0.5 M sodium chloride where 95% of the cell debris and 88% of the nucleic acids could be removed from the disintegrate by sedimentation, leaving 99% of proteins and 86% of -galactosidase enzyme activity in clarified solution. We will also discuss the mechanisms for interaction between chitosan and different groups of components in the disintegrate: cell debris particles, nucleic acid polymers and proteins.

    Abstract [en]

    A new joint research project (JRP) integrating metrology institutes and universities from nine countries is aimed at realization of a new generation of standards for quantum resistance metrology. The project exploits graphene's properties to simplify operation of standards without compromising the unprecedented precision delivered by semiconductor quantum Hall devices. Higher operating temperatures (above 4.2 K, and up to 8 K) and together with lower magnetic fields (below 5 T, and potentially down to 2 T) will lead to a significantly improved and cost-saving dissemination of intrinsically referenced resistance standards to all end-users relying on electrical measurements.

    Ammonium nitrate fertiliser production based on biomass: Environmental effects from a life cycle perspective2008Inngår i: Bioresource Technology, ISSN 0960-8524, E-ISSN 1873-2976, Vol. 99, nr 17, s. 8034-8041Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ammonium nitrate and calcium ammonium nitrate are the most commonly used straight nitrogen fertilisers in Europe, accounting for 43% of the total nitrogen used for fertilisers. They are both produced in a similar way; carbonate can be added as a last step to produce calcium ammonium nitrate. The environmental impact, fossil energy input and land use from using gasified biomass (cereal straw and short rotation willow (Salix) coppice) as feedstock in ammonium nitrate production were studied in a cradle-to-gate evaluation using life cycle assessment methodology. The global warming potential in the biomass systems was only 22-30% of the impact from conventional production using natural gas. The eutrophication potential was higher for the biomass systems due to nutrient leaching during cultivation, while the acidification was about the same in all systems. The primary fossil energy use was calculated to be 1.45 and 1.37 MJ/kg nitrogen for Salix and straw, respectively, compared to 35.14 MJ for natural gas. The biomass production was assumed to be self-supporting with nutrients by returning part of the ammonium nitrate produced together with the ash from the gasification. For the production of nitrogen from Salix, it was calculated that 3914 kg of nitrogen can be produced every year from 1 ha, after that 1.6% of the produced nitrogen has been returned to the Salix production. From wheat straw, 1615 kg of nitrogen can be produced annually from 1 ha, after that 0.6% of the nitrogen has been returned. © 2008 Elsevier Ltd. All rights reserved.

    Future fuel supply systems for organic production based on Fischer-Tropsch diesel and dimethyl ether from on-farm-grown biomass2008Inngår i: Biosystems Engineering, ISSN 1537-5110, E-ISSN 1537-5129, Vol. 99, nr 1, s. 145-155Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The effects of making a 1000 ha organic farm self-sufficient in renewable fuel were studied. Biomass grown on-farm can be transported to large fuel production facilities and the fuel transported back to the farm. Two fuels, Fischer-Tropsch diesel (FTD) and dimethyl ether (DME), produced from either straw or short-rotation willow coppice (Salix), were studied. The environmental impact, land use and energy balance were calculated using life-cycle methodology. It was calculated that the straw-based systems had only 32-39% of the impact on global warming (kg [CO2-eq]) compared to the Salix-based systems. For acidification and eutrophication, the differences between the systems were less significant. The energy balances were 8.9 and 9.6 for FTD and 10.1 and 10.0 for DME, from straw and Salix, respectively. To become self-sufficient in FTD, 108 ha has to be set aside for Salix production or 261 ha of straw collected from the existing crop rotation. For DME the corresponding figures are 38 and 70 ha. The many by-products in the FTD scenarios explain the large difference between fuels. Comparing FTD and DME, the differences in environmental impact were small. Considering this, FTD is a more likely alternative since DME requires a pressurised infrastructure system and engine modifications. © 2007 IAgrE.

    Tractive power in organic farming based on fuel cell technology: Energy balance and environmental load2009Inngår i: Agricultural Systems, ISSN 0308-521X, E-ISSN 1873-2267, Vol. 102, nr 1-3, s. 67-76Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study analysed a future hypothetical organic farm self-sufficient in renewable tractor fuel. Biomass from the farm was assumed to be transported to a central fuel production plant and the fuel returned to the farm, where it was utilised in fuel cell powered tractors. The land use, energy balance and environmental impact of five different scenarios were studied. In the first two scenarios, straw was used as raw material for production of hydrogen or methanol via thermochemical gasification. In the third and fourth scenarios, short rotation forest (Salix) was used as raw material for the same fuels. In the fifth scenario, ley was used as raw material for hydrogen fuel via biogas production. The straw scenarios had the lowest impact in all studied environmental impact categories since the Salix scenarios had higher soil emissions and the ley scenario had comparatively large emissions from the fuel production. The energy balance was also favourable for straw, 16.3 and 19.5 for hydrogen and methanol respectively, compared to Salix 14.2 and 15.6. For ley to hydrogen the energy balance was only 6.1 due to low efficiency in the fuel production. In the Salix scenarios, 1.6% and 2.0% of the land was set aside for raw material production in the hydrogen and methanol scenarios respectively. In the straw scenarios no land needed to be reserved, but straw was collected on 4.3% and 5.3% of the area for hydrogen and methanol respectively. To produce hydrogen from ley, 4% of the land was harvested. The study showed that the difference in environmental performance lay in choice of raw material rather than choice of fuel. Hydrogen is a gas with low volumetric energy density, which requires an adapted infrastructure and tractors equipped with gas tanks. This leads to the conclusion that methanol probably will be the preferred choice if a fuel cell powered farm would be put into practice in the future. © 2009 Elsevier Ltd. All rights reserved.

    Review of methodological choices in LCA of biorefinery systems - key issues and recommendations2015Inngår i: Biofuels, Bioproducts and Biorefining, ISSN 1932-104X, E-ISSN 1932-1031, Vol. 9, nr 5, s. 606-619Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The current trend in biomass conversion technologies is toward more efficient utilization of biomass feedstock in multiproduct biorefineries. Many life-cycle assessment (LCA) studies of biorefinery systems have been performed but differ in how they use the LCA methodology. Based on a review of existing LCA standards and guidelines, this paper provides recommendations on how to handle key methodological issues when performing LCA studies of biorefinery systems. Six key issues were identified: (i) goal definition, (ii) functional unit, (iii) allocation of biorefinery outputs, (iv) allocation of biomass feedstock, (v) land use, and (vi) biogenic carbon and timing of emissions. Many of the standards and guidelines reviewed here provide only general methodological recommendations. Some make more specific methodological recommendations, but these often differ between standards. In this paper we present some clarifications (e.g. examples of research questions and suitable functional units) and methodological recommendations (e.g. on allocation).
