  2. 1. Human salivary esterases : a biochemical study of carboxylesterase and thio-esterase in human saliva with special reference to their inhibition by dental materials

    Author : Lennart Lindqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Electrophoretic and gel chromatographic techniques have been developed in order to obtain partially purified esterases from small amounts of human saliva. These techniques permit the characterization of salivary esterase regarding substrate and inhibitor specificities, and lectin binding ability. READ MORE

  4. 2. Exploring and exploiting plant biomass degradation by Bacteroidetes

    Author : Cathleen Kmezik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polysaccharide utilization locus; plant biomass degradation; carbohydrate esterases; multidomain enzymes; Bacteroidetes; PUL transfer; carbohydrate-active enzymes; xylan;

    Abstract : Bacteroidetes bacteria have evolved to become excellent biomass degraders. They achieved this by applying carbohydrate-active enzymes (CAZymes) and organizing genes connected to the degradation of specific polysaccharides into discrete gene cassettes, so-called polysaccharide utilization loci (PULs).

  5. 3. Feruloyl esterases - Evaluation of their potential for biotechnological applications

    Author : Cyrielle Bonzom; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Enzymes for selective decoupling of woody biomass: From fundamentals to industrial potential

    Author : Jenny Arnling Bååth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulose; glucuronoyl esterase; polysaccharide acetylation; carbohydrate esterase family 15; woody biomass; materials biorefinery; enzyme accessibility; lignin-carbohydrate bonds; mannanase; galactoglucomannan;

    Abstract : The need for an economy based on renewable materials has resulted in growing interest in the use of woody biomass in a wider field of application. However, the chemical complexity of lignocellulose and the dense structure of wood pose challenges in its processing. READ MORE

  7. 5. Enzyme assays for lignin–carbohydrate bond hydrolysis

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

    Abstract : 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. READ MORE
