  1. 1. Discovery and applications of family AA9 lytic polysaccharide monooxygenases

    Författare :Monika Tõlgo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lytic polysaccharide monooxygenases; cellulose; xylan; spruce; carbohydrate active enzymes; LPMO; lignocellulolytic enzyme cocktails; lignocellulose; polysaccharides; AA9; cellulose nanocrystals; thermophilic fungi;

    Sammanfattning : Auxililary activity family 9 lytic polysaccharide monooxygenases (abbreviated as AA9s or LPMO9s) are fungal mono-copper enzymes capable of oxidatively cleaving various plant cell wall oligo- and/or polysaccharides. LPMO9s are key components of lignocellulolytic enzyme cocktails used in today’s biorefineries to break down biomass into fermentable sugars. LÄS MER

  3. 2. Depolymerization of Lignocellulose by Lytic Polysaccharide MonoOxygenases

    Författare :Madhu Nair Muraleedharan; Paul Christakopoulos; Ulrika Rova; Mats Sandgren; Johan Larsbrink; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : Lignocellulose biomass is considered as one of the most potential and sustainable sources for the production of value-added chemicals and fuels while replacing the traditional petroleum resources. In a biorefinery, by employing biochemical conversion processes,cellulose present in the biomass is broken down into monomeric sugars which can belater converted into fuels or chemicals. LÄS MER

  4. 3. Lytic polysaccharide monooxygenases for green production of cellulose nanomaterials

    Författare :Salla Koskela; Qi Zhou; Markus Linder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose; enzyme; CNC; CNF; LPMO; nanocellulose; wood; Biotechnology; Bioteknologi;

    Sammanfattning : Cellulose is the main structural polymer in wood, and its potential in the form of nanomaterial building blocks, nanocelluloses, has now been recognized. Nanocelluloses, including cellulose nanofibers (CNFs) and cellulose nanocrystals (CNCs), have become increasingly important in development of modern sustainable materials. LÄS MER

  5. 4. Dissecting function and catalytic mechanism of fungal lytic polysaccharide monooxygenases

    Författare :Bing Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fungi use a complex and well-orchestrated enzyme machinery to degrade lignocellulose biomass, in which both hydrolytic and redox enzymes are involved. Lytic polysaccharide monoxygenases (LPMOs) are copper-dependent enzymes that cleave bonds in polysaccharides using oxidative mechanisms. LÄS MER

  7. 5. Lytic Polysaccharide MonoOxygenases; their role for lignocellulose depolymerization and production of (functional) biobased compounds

    Författare :Madhu Muraleedharan Nair; Paul Christakopoulos; Ulrika Rova; Mats Sandgren; Francisco Vilaplana; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : Increased environmental concerns over petroleum-based products triggered the quest to find a sustainable alternative for fuels, chemicals etc. Lignocellulose biomass, due to its abundance, is considered as one of the most promising sustainable sources for the production of fuels and chemicals, while replacing the traditional petroleum resources.
