  2. 16. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

    Author : Evelina Kulcinskaja; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

    Abstract : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. READ MORE

  4. 17. Chemical characterization in the biorefinery of lignocellulose : Formation and management of oxalic acid and analysis of feedstocks for bioethanol production

    Author : Anders Sjöde; Nils-Olof Nilvebrant; Leif J. Jönsson; Arthur J. Ragauskas; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biorefinery; enzymes; ethanol; lignocellulosic feedstocks; oxalic acid; scaling; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : The pulp and paper industry is entering a new era. Pulp mills will be transformed to biorefineries that produce not only pulp, but also biofuels and novel products from lignocellulose. This thesis addresses problems connected with the industrial transition to environmental-friendly technologies and the implementation of the biorefinery concept. READ MORE

  5. 18. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

    Author : Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

    Abstract : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. READ MORE

  6. 19. Physico-chemical characterisation of novel surfactants

    Author : Britta M. Folmer; KTH; []
    Keywords : Natural raw materials; novel hydrophobes; physico-chemical characterisation; micelles; interfacial adsorption; liquid crystals; enzymes; polymers; complex formation; foam;

    Abstract : The aim of this thesis has been to investigate thephysico-chemical behaviour of novel surfactants based onnatural raw materials. Micellization properties, adsorptionatinterfaces and dynamic aspects have been studied. In additioncomplex formation of surfactants with enzymes and polymers hasbeen evaluated. READ MORE

  7. 20. Mechanistic Studies of Dinuclear Metalloenzymes - A Model Approach

    Author : Håkan Carlsson; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; models; Enzymes; bioinorganic chemistry; dinuclear; urease; nickel; zinc triphosphoesterase; Oorganisk kemi; Inorganic chemistry;

    Abstract : With the goal to study the mechanisms of dinuclear metalloenzymes, a new line of synthetic and computational models were prepared and studied. Mixed imidazole and carboxylate multidentate complexes were synthesized to better simulate carboxylate-rich ligand environments. READ MORE
