  3. 2. Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution

    Författare :Johan Borgström; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polysaccharide; physical gel; ion binding; carrageenan; liquid crystal; polymer; Fysikalisk kemi;

    Sammanfattning : The phase behaviour and gelation of the anionic polysaccharide kappa-carrageenan (KC) in different salt solutions was studied. The specific site binding of certain anions and certain cations to the KC helix was used as a means of controlling the interactions. LÄS MER

  4. 3. Metabolic Engineering of Disaccharide Catabolism for Polysaccharide Formation in Lactococcus lactis and Streptococcus thermophilus

    Författare :Fredrik Levander; Institutionen för immunteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; metabolic engineering; exopolysaccharide; polysaccharide; disaccharide; Streptococcus thermophilus; lactic acid bacteria; Lactococcus lactis; Biochemical technology; Biokemisk teknik; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Exopolysaccharides (EPSs) produced by the lactic acid bacteria (LAB) Lactococcus lactis and Streptococcus thermophilus are important for the rheological behaviour and texture of a variety of fermented food products. Furthermore, EPSs from food-grade LAB have potential as food additives and functional food ingredients with both health and economic benefits. LÄS MER

  5. 4. Polysaccharide-based wood adhesives

    Författare :Tijana Todorovic; Eva Malmström; Linda Fogelström; Johannes Konnerth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : It is highly desirable to increase the use of renewable resources and reduce fossil-dependence due to sustainability concerns. As a consequence, it is expected that the use of the wood-based materials will increase in the future. Therefore, adhesives will have an important role since they allow for the use of lower-quality and recycled wood. LÄS MER

  7. 5. Interfacial Properties of Biomacromolecular Model Systems: Surface Forces and Nanotribology

    Författare :Niklas Nordgren; Mark Rutland; Harry Brumer III; Robert Pelton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; afm; surface force; friction; composite material; model surface; quartz crystal microbalance; dissipation; cellulose; xyloglucan; chitosan; colloidal probe; nanotribology; biomimetic; enzymatic; polysaccharide; graft; fiber; thiol; spring constant; calibration; lubrication; polyion; responsive.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The nanotribology, adhesion and related interfacial properties of biomacromolecular systems have been studied.  The aim was to elucidate the role of physisorbed and chemically grafted bio-polymers implicated as mediators for cellulose based processing and material design.
