  1. 1. Enzyme assays for lignin–carbohydrate bond hydrolysis

    Författare :Hampus Sunner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enzyme kinetic param- eter estimation; Glucuronoyl esterase; Enzyme assays; Lignin-carbohydrate bonds; Synergistic enzyme assay;

    Sammanfattning : To identify, produce, and use enzymes, analytical methods known as enzyme assays are employed. Enzyme assays are based on analysing the changes brought about on a substrate by an enzyme under defined conditions. Assays are often based on simplified reactions acting as substitutes for the reaction of interest. LÄS MER

  3. 2. Rational engineering of esterases for improved amidase specificity in amide synthesis and hydrolysis

    Författare :Peter Hendil-Forssell; Mats Martinelle; Romas J. Kazlauskas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amidase; Biocatalysis; Enzyme; Esterase; Enzyme engineering; Lipase; Substrate specificity; Bioteknologi; Biotechnology;

    Sammanfattning : Biocatalysis is an ever evolving field that uses enzymes or microorganisms for chemical synthesis. By utilizing enzymes that generally have evolved for specific reactions under mild conditions and temperatures, biocatalysis can be a more environmentally friendly option compared to traditional chemistry.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-domain enzyme; acetyl esterase; enzyme immobilization; N-glycosylation; carbohydrate active enzyme family 1; acetyl xylan esterase; heterologous production; polysaccharide utilization loci; enzyme stability; feruloyl esterase;

    Sammanfattning : Owing to the current efforts to find sustainable alternatives to petrochemical based industries and technologies, enzymatic degradation and valorization of plant biomass has been attracting interest. Due to the complexity of plant biomass, an array of enzymes is required to hydrolyze it, including esterases. LÄS MER

  5. 4. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

    Författare :Zubaida Gulshan Kazi; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycoside hydrolase; transglucosylation; alkyl glycoside; cyclodextrin glucanotransferase; Rhodothermus marinus; xylanases; hydrolysis; beta-glucosidases;

    Sammanfattning : Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. LÄS MER

  7. 5. New Methods for Enzyme Hydrolysis, Analysis, and Characterization of Modified Cellulose

    Författare :Claes Melander; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Methyl Cellulose; Reducing End; Micro Immobilised Enzyme Reactor; Mass Spectrometry; Enzyme Hydrolysis; Modified Cellulose; Substituent Distribution;

    Sammanfattning : Cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution, origin of cellulose and properties are importaint in order to design processess so as to produce derivatives with the desired properties.
