1. 1. The kinetics of cellulose enzymatic hydrolysis : Implications of the synergism between enzymes

   Författare :Priit Väljamäe; Jan-Christer Janson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Acetobacter; Cellobiohydrolase; Cellobiose; Cellulase; Cellulose; Diffusion; Endoglucanase; Hydrolysis; Inhibition; Kinetics; Model; Product; Substrate; Surface; Synergism; Trichoderma reesei; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : The hydrolysis kinetics of bacterial cellulose and its derivatives by Trichoderma reesei cellulases was studied. The cellulose surface erosion model was introduced to explain the gradual and strong retardation of the rate of enzymatic hydrolysis of cellulose. LÄS MER

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

   Författare :Jozsef Medve; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FPLC; cellulose hydrolysis; Trichoderma reesei; cellulase; cellobiohydrolase; endoglucanase; adsorption isotherm; synergism; enzyme purification; isoenzymes; quantitative analysis; Biochemistry; Metabolism; Biokemi;

   Sammanfattning : 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. LÄS MER

4. 3. Hydrolytic and Oxidative Mechanisms Involved in Cellulose Degradation

   Författare :Anu Nutt; Jerry Ståhlberg; Henrik Stålbrand; Uppsala universitet; []
   Nyckelord :Biochemistry; cellobiohydrolase; cellulase; cellulose; cellobiose dehydrogenase; endoglucanase; kinetics; synergism; competitive binding; Biokemi;

   Sammanfattning : The enzymatic degradation of cellulose is an important process in nature. This thesis has focused on the degradation of cellulose by enzymes from two cellulose-degrading fungi, Hypocrea jecorina and Phanerochaete chrysosporium, including both the action of the individual enzymes and their synergistic interplay.

5. 4. Studies of extraction and separation of Am(III) and Eu(III) using synergistic extraction with nitrogen coordinating ligands and 2-bromodecanoic acid

   Författare :Åsa Enarsson; Chalmers tekniska högskola; []
   Nyckelord :transmutation; oligopyridines; Am; lathanide; solvent extraction; basicity; actinide; separation; synergism; triazines; Eu;

   Sammanfattning : .... LÄS MER

7. 5. Adsorption of polyhydroxyl based surfactants

   Författare :Maria Matsson; Per Claesson; Robert Meszaros; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; surface chemistry; adsorption; surfactant; nonionic; alkyl glucoside APG ; ellipsometry; kinetics; alkyl amine oxide DDAO ; alkyl ammonium bromide DTAB ; solid liquid interface; synergism; coadsorption.;

   Sammanfattning : Adsorption on solid surfaces from solution is a fundamental property of a surfactant. It might even be the most important aspect of surfactant behavior, since it influences many applications, such as cleaning, detergency, dispersion, separation, flotation, and lubrication. LÄS MER
