  1. 1. Flow processing and gel formation for producing biopolymer drops with functional shapes and diffusion properties

    Författare :Bernhard Walther; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; drop deformation; 4-roll mill; biopolymer; agarose; shear; Kappa-carrageenan; elongation; microstructure; flow processing; drop-shaping; rheology; poly ethyleneglycol ; diffusion; gelatine; NMR; gel formation; TEM; flow channel;

    Sammanfattning : This thesis focuses on the development of novel processes which combine flow-induced drop deformation and simultaneous temperature-induced gel formation in order to create shaped biopolymer drops. The drops are functional in terms of rheology and diffusion properties, factors strongly influencing the consistency of food products and flavour or drug release. LÄS MER

  3. 2. Physico-chemical characterisation of novel surfactants

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

    Sammanfattning : 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. LÄS MER

  4. 3. Effects of fusion tags on protein partitioning In aqueous two-phase systems and use in primary protein recovery

    Författare :Cynthia Hassinen; KTH; []
    Nyckelord :E. coli; Aqueous two-phase systems; Fusion proteins; Hydrophobic interaction chromatography; Expanded bed adsorption; Beta-galactosidase; Klenow polymerase; Z-domain; Peptide tags;

    Sammanfattning : The two techniques aqueoustwo-phase partitioning and expanded bed adsorption that bothare suitable for primary protein recovery were studied. Most ofthe work was focused on partition in aqueous two-phase systemsand in particular on the possibility to effect the partitionbehaviour by fusion of short peptide tags or protein domains tothe target protein.
