    Sammanfattning : Microbial chlorate respiration plays an important role in the turnover of oxochlorates in nature and industrial waste management. This thesis deals with the characterization of the molecular components of chlorate respiration in Ideonella dechloratans. LÄS MER

  3. 2. Oxygen-dependent regulation of key components in microbial chlorate respiration

    Författare :Miriam Hellberg Lindqvist; Thomas Nilsson; Stefan Nordlund; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic respiration; Gene expression; Chlorate; Chlorate reductase; Chlorite dismutase; Kemi; Chemistry;

    Sammanfattning : Contamination of perchlorate and chlorate in nature is primarily the result of various industrial processes. The microbial respiration of these oxyanions of chlorine plays a major role in reducing the society’s impact on the environment. LÄS MER

  4. 3. Electron transport in microbial chlorate respiration

    Författare :Anna Smedja Bäcklund; Thomas Nilsson; Åke Strid; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c cytochromes; chlorate reduction; electron transport; c cytokromer; kloratreduktion; elektrontransport; Biochemistry; Biokemi; Kemi; Chemistry;

    Sammanfattning : Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. Microbial respiration of oxochlorates is important for biotreatment of effluent from industries where oxochlorates are produced or handled. LÄS MER

  5. 4. c Cytochromes as Electron Carriers in Microbial Chlorate Respiration

  7. 5. Electrochemical Investigations of Water and Hypochlorite Reduction on a-and y-FeOOH

    Författare :Kristoffer Hedenstedt; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sodium chlorate; corrosion; electrodeposition; goethite; lepidocrocite; hypochlorite reduction; hydrogen evolution;

    Sammanfattning : The cathodes in the electrochemical cells used for production of sodium chlorate process are made from mild steel. Due to the harsh environment in the chlorate cell, with oxidative species such as chlorate and hypochlorous acid, the cathodes corrodes. This corrosion might be beneficial, leading to surface enlargement and lower potential. LÄS MER
