  2. 11. Assessing the toxic impact of chemicals using bacteria

    Author : Jenny Gabrielson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Bacteria; toxicity testing; ecotoxicity; phylogenetic diversity; growth inhibition;

    Abstract : There is a considerable backlog in the testing of new chemical compounds for their ecotoxic properties, mostly due to the lack of appropriate testing methods. In addition, there is a vivid debate today about the test endpoint for many of the existing methods. READ MORE

  4. 12. The Alzheimer Aβ Peptide : Identification of Properties Distinctive for Toxic Prefibrillar Species

    Author : Anna-Lena Göransson; Jenny Presto; Linköpings universitet; []
    Keywords : ;

    Abstract : Proteins must have specific conformations to function correctly inside cells. However, sometimes they adopt the wrong conformation, causing dysfunction and disease. A number of amyloid diseases are caused by misfolded proteins that form amyloid fibrils. One such disease is Alzheimer’s disease (AD). READ MORE

  5. 13. Effects of toxin-producing phytoplankton on copepods: feeding, reproduction and implications to the fate of toxins

    Author : Betina Kozlowsky-Suzuki; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; GSH transferase; oocyte development; fate of toxins; toxin accumulation; toxic phytoplankton; copepods;

    Abstract : Phytoplankton growth and loss rates are governed by several factors and in many cases, when growth control fails, algal blooms are established. Such blooms can be formed by different phytoplankton species and some of them have harmful impacts on marine ecosystems. READ MORE

  7. 15. Studies to Avoid Decreased Efficiency in Multiple Stage Biological Wastewater Treatment Plants: Concerning Forests Industry Effluents

    Author : Maria Sandberg; Ola Holby; Erik Särner; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment; Forest industry; Black liquor; MultiBio; Toxic effluents; Environmental engineering; Miljöteknik; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Målet med den här studien är att förhindra effektivitetssänkningar i moderna biologiska reningsanläggningar för skogsindustriella avloppsvatten. Biologiska processer är vanligtvis effektiva när det gäller att reducera lättnedbrytbart organiskt material. Eftersom den utgörs av levande mikroorganismer (MO) är tekniken känslig. READ MORE
