  2. 1. 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

  4. 2. RECOMBINANT PEROXIDASES AND XYLANASES: I. Cloning and production of a peroxidase from horseradish II. Characterisation of functional domains of thermostable xylanases from Rhodothermus marinus

    Author : Eva Bartonek Roxå; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous cellulose; xylan; CBD; carbohydrate binding domains; insect cells; Baculovirus; catalytically active; recombinant horseradish peroxidase; HRP-n; PASC; beta-glucan; Biotechnology; Bioteknik;

    Abstract : Part I: Plant peroxidases are useful in many areas of application e.g. as tracer enzymes for clinical applications and in biosensors as well as for industrial purposes like in waste water treatment and bleaching processes. A gene encoding a new, neutral horseradish peroxidase isoenzyme, HRP-n, was isolated. READ MORE

  5. 3. In vitro and in vivo oxidation of diastereomers of lignin models of arylgylcerol b-aryl ether type and heterologous expression of laccase

    Author : Christina Bohlin; Leif Jönsson; Ming Tien; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : Enzymic and non-enzymic oxidation of lignin models of the arylglycerol β-aryl ether type was investigated in experiments aimed at providing a better understanding of the initial phase of biological lignin degradation. Product profiles and diasteromer selectivity were determined to gain knowledge of the properties of the oxidants and pave the way for evaluation of the presence of the oxidants in ligninolytic fungal cultures.

  6. 4. Functional ecology of ectomycorrhizal fungi : peroxidases, decomposition, spatial community patterns

    Author : Inga Bödeker; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Boreal forest ecosystems constitute a globally important carbon (C) sink, due to accumulation of complex organic matter, persistent to decomposition. Nitrogen (N) is immobilized in these complex compounds and, thereby, unavailable to the plant community. READ MORE

  7. 5. Microbial Degradation of Toxaphene

    Author : Martha Lacayo; Avdelningen för arbets- och miljömedicin; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Enterobacter; Environmental technology; Bjerkandera; Toxaphene; Biodegradation; Biotechnology; Bioteknik;

    Abstract : This works deals with the degradation of a group of recalcitrant compounds known as toxaphene. Toxaphene is a complex mixture of chlorinated compounds including hexa- and octachlorocamphenes, hepta-, nona- and decachlorobornanes. Some components of toxaphene are very persistent while others are degraded rapidly by both abiotic and biotic processes. READ MORE
