    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose synthase; Populus; secondary cell wall; gene upregulation; cell suspension culture; stationary phase; Bioengineering; Bioteknik;

    Sammanfattning : Cellulose is a biopolymer of great relevance in the plant cell walls, where it constitutes the most important skeletal component. Cellulose is also an important raw material in the pulp- and paper, forest, and textile industries, among others. LÄS MER

  3. 2. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

    Författare :David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Lars Lövgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; Environmental engineering; Miljöteknik; Water engineering; Vattenteknik; Soil chemistry; Markkemi;

    Sammanfattning : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

  4. 3. Sustainable phosphorus removal in onsite wastewater treatment

    Författare :David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Paul Withers; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Onsite wastewater treatment; Soil treatment system; Phosphorus; Removal mechanisms; Environmental impacts; Life cycle assessment;

    Sammanfattning : Aquatic eutrophication is a serious environmental problem that occurs all over the world. To protect surface waters (in particular the Baltic Sea), the regulatory pressure on onsite wastewater treatment (OWT) systems have increased in Sweden. LÄS MER

  7. 5. Biotic Ligand model : A tool for risk assessment of metals in Scandinavian fresh waters?

    Författare :Sabina Hoppe; Magnus Breitholtz; Jon-Petter Gustafsson; Karel De Schamphelaere; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BLM; Soft freshwaters; Sweden; Cu; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Products from iron and copper mining are among Sweden’s top exports. However, as the metals are excavated, they often end up in the aquatic environment where they can cause toxicity. LÄS MER
