  2. 1. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides

    Author : Maria Henriksson; Tuula Teeri; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; glycosynthase; Pichia pastoris; fed-batch fermentation; expanded-bed adsorption; Plant biotechnology; Växtbioteknik;

    Abstract : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. READ MORE

  4. 2. Improving cellulose fibre properties by controlled adsorption of xylans

    Author : Tobias Köhnke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Isolation; Lignin-carbohydrate complexes; Adsorption; Extraction; Tensile strength; Aggregation; Softwood kraft pulp; Cellulose fibre; Hornification; Xylan;

    Abstract : Hemicelluloses are, together with cellulose and pectins, the polysaccharide constituents in the cell walls of higher plants. Xylans are the most common hemicelluloses, and are considered to be the second most abundant biopolymer in the plant kingdom. READ MORE

  5. 3. Iodine-Metal Surface Interactions under Severe Accident Conditions in a Nuclear Power Plant

    Author : Henrik Glänneskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; containment; reactive metals; BWR; adsorption; iodine; radiolysis;

    Abstract : In the event of a severe nuclear reactor accident, iodine will be released from the fuel and eventually enter the containment. Radioactive iodine isotopes constitute both an acute and a long-term threat to humans, owing to its half-life and its accumulation in the thyroid gland. READ MORE

  6. 4. Transport of Heavy Metals in Soil Subjected to an Electric Field -A Study of the Transport of Copper in Bentonite Clay

    Author : Klas Arnerdal; KTH; []
    Keywords : Electrokinetic soil remediation; bentonite; copper; adsorption; electromigration; electroosmosis; pH; potential;

    Abstract : This licentiate thesis addressesphosphorus release from sewage sludge, which is the first stepin phosphorus recovery. The concept ofphosphorus recovery maybe seen as a part of sustainable sludge handling in that it isa means of recycling resources without supplying harmfulsubstances to humans or the environment.

  7. 5. Effects of Natural Organic Matter on Herbicide Adsorption to Activated Carbon

    Author : Åsa Edell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural organic matter; herbicide; adsorption isotherm; preloading; activated carbon; competitive interaction;

    Abstract : The presence of pesticides in the aquatic environment represents a potential threat to water quality and human health. Increasingly stringent drinking water quality directives focus on the need for efficient pesticide removal processes. READ MORE
