  1. 1. Cellulose hydrolysis by Trichoderma reesei cellulases: Studies on adsorption, sugar production and synergism of cellobiohydrolase I, II and endoglucanase II

    University dissertation from Department of Biochemistry, Lund University

    Author : Jozsef Medve; Lunds universitet.; Lund University.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; FPLC; cellulose hydrolysis; Trichoderma reesei; cellulase; cellobiohydrolase; endoglucanase; adsorption isotherm; synergism; enzyme purification; isoenzymes; quantitative analysis; Biochemistry; Metabolism; Biokemi;

    Abstract : Three major cellulases, cellobiohydrolase I and II (CBH I and II) and endoglucanase II (EG II) of Trichoderma reesei have been purified by ion-exchange chromatography in an FPLC system. Microcrystalline cellulose (Avicel) was hydrolysed by the single enzymes and by equimolar mixtures of CBH I-CBH II and CBH I-EG II. READ MORE

    Abstract : Popular Abstract in Swedish Ett av dagens stora miljöproblem är de höga halter av koldioxid som ackumuleras i atmosfären. En stor del av samhällets koldioxidutsläpp kommer från förbränning av fossila bränslen som kol, olja eller bensin. READ MORE

  3. 3. Ethanol from Softwood - Process Development Based on Steam Pretreatment and SSF

    University dissertation from Kerstin Stenberg, Chemical Engineering, Lund University

    Abstract : Popular Abstract in Swedish Denna avhandling handlar om hur bränsleetanol kan produceras från barrved för att användas som ersättning för bensin. Den största fördelen med detta är att genom att använda etanol tillverkad av råmaterial från växtriket ökar vi inte växthuseffekten. READ MORE

  4. 4. Modeling of enzyme kinetics on polymeric substrates by simulation : Enzymatic hydrolysis of cellulose

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Veljo Sild; Uppsala universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : Biopolymers are an essential constituent of living matter. To develop new products and processes based on enzyme production and modification and hydrolysis of biopolymers, enzymes with well understood mechanism are required. It is impossible to derive a universal analytical model for every particular enzyme/polymer system. READ MORE

  5. 5. Biorefining of lignocellulose Detoxification of inhibitory hydrolysates and potential utilization of residual streams for production of enzymes

    University dissertation from Umeå : Umeå universitet

    Author : Adnan Cavka; Umeå universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Lignocellulosic biomass is a renewable resource that can be utilized for the production of biofuels, chemicals, and bio-based materials. Biochemical conversion of lignocellulose to advanced biofuels, such as cellulosic ethanol, is generally performed through microbial fermentation of sugars generated by thermochemical pretreatment of the biomass followed by an enzymatic hydrolysis of the cellulose.
