  2. 1. Laccases from New Fungal Sources and Some Promising Applications

    Author : Laura Mendoza; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fungi; ligninases; modification of primary alcohols; modification of lignin; laccase applications; dye decolorization;

    Abstract : Fungi are a group of organisms with the ability to produce different types of enzymes in order to get access to nutrients. Among the enzymes, oxidoreductases have the ability to degrade lignocellulosic material via an oxidative mechanism, facilitating the uptake of cellulosic material, which will be metabolized using other enzymes to provide the required nutrients to the fungi.

  4. 2. 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

  5. 3. Modified and hybrid cellulose-based materials for water purification

    Author : Dimitrios Georgouvelas; Aji Mathew; Henrikki Liimatainen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose; lignocellulose; membranes; water treatment; heavy metal adsorption; dye adsorption; scalability; materialkemi; Materials Chemistry;

    Abstract : The need for clean water has led to the development of several different water treatment methods as well as to a large number of organic, inorganic, hybrid and/or composite materials that are used in these methods. Cellulose, being a highly abundant biopolymer with meritorious properties, such as high mechanical strength, tunable surface chemistry, high aspect ratio and surface area, to mention a few, is exploited in the current thesis for water treatment applications.
