  5. 18. Reactive dissolved organic carbon dynamics in a changing environment : Experimental evidence from soil and water

    Author : Balathandayuthabani Panneer Selvam; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon; DOC; Photodegradation; Biodegradation; DOC reactivity;

    Abstract : Dissolved organic carbon (DOC) is the major form of organic carbon in aquatic ecosystems. Biological and photochemical degradation of DOC are major causes of greenhouse gas emissions from aquatic ecosystems. READ MORE

    Abstract : Brominated flame retardants (BFRs) are chemicals used in e.g. electronic equipment, textiles and plastics for the prevention of fire. Over recent decades, concern has been raised regarding some heavily used BFRs, since the levels in the environment have been increasing. READ MORE

  7. 20. Fungal Redox Enzymes Involved in the Oxidation of Organic Pollutants

    Author : Enrique Terrazas; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Biokemisk teknik; Organic pollutants.; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Biochemical technology; Laccase; Lignin peroxidase; Manganese peroxidase; Fusarium sp. strain BOL35; Biodegradation; Bjerkandera sp. strain BOL13; Bioteknik;

    Abstract : This work describes the degradation of nonylphenol, toxaphene, phenanthrene, benzo[a]pyrene and dyes using fungi and their redox enzymes. Two fungi, Bjerkandera sp. strain BOL13 and Fusarium sp. strain BOL35 were isolated from different geographic area in Bolivia. READ MORE
