    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

  4. 3. 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

  5. 4. Critical potential and oxygen evolution of the chlorate anode

    Författare :Linda Nylén; Göran Lindbergh; Yohannes Kiros; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chlorate; chloride oxidation; oxygen evolution; critical anode potential; chromate; DSA; mass transport; RDE; Chemical engineering; Kemiteknik;

    Sammanfattning : In the chlorate process, natural convection arises thanks to the hydrogen evolving cathode. This increases the mass transport of the different species in the chlorate electrolyte. There is a strong connection between mass transport and the kinetics of the electrode reactions. LÄS MER
