  1. 1. Lactic acid bacteria fermentations in oat-based suspensions

    Författare :Olof Mårtensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beta-glucans; probiotics; prebiotics; bacterial survival; Food and drink technology; Livsmedelsteknik; oats; ropiness; lactic acid bacteria; ropy;

    Sammanfattning : This thesis deals with the fermentation characteristics of lactic acid bacteria (LAB) in oat-based suspensions, with formulation work of fermented products based on oat and with nutritional studies of these products. Changes in structure in terms of viscosity and ropiness were studied when exopolysaccharide (EPS)-producing LAB strains, namely, Lactobacillus delbrueckii subsp. LÄS MER

  3. 2. Optically pure lactic acid production from lignocellulosic biomass

    Författare :Joana Coutinho Campos; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lactic acid; enantiomers; softwood; waste viscose; fermentation; Pediococcus acidilactici;

    Sammanfattning : Lactic acid is a platform chemical that can be used for many applications. More recently, optically pure lactic acid—L- or D-lactic acid enantiomers—have been used for the polymerisation to poly-lactic acid (PLA). LÄS MER

  4. 3. Influence of Lactic Acid Fermentation on Enteropathogenic Bacteria. Growth Inhibition in Cereal Gruels and in Human Intestine

    Författare :Rose Kingamkono; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intestinal mucosal permeability; enteropathogenic bacteria; enterotoxins; lactic acid fermentation;

    Sammanfattning : Togwa, a lactic-fermented cereal gruel, is widely consumed in Tanzania as a soft drink or used as a complementary food for young children. Studies were conducted to evaluate the potential of togwa to inhibit growth of common enteropathogenic bacteria and heat-labile (LT) enterotoxin production. LÄS MER

    Sammanfattning : Antibiotic resistance is now a large threat with worldwide agreement that we will fall into a post-antibiotic era unless there is suitable treatment alternatives discovered. In recent years, chronic wounds have become a major burden on society and treatment is complicated. LÄS MER
