  2. 1. Systematics of Lactobacillus spp. of probiotic potential

    Author : Alejandra Vasquez; Avdelningen för medicinsk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mikrobiologi; bakteriologi; virologi; mykologi; Food and drink technology; Livsmedelsteknik; mycology; virology; bacteriology; Microbiology; bacteria; molecular-based identification; probiotics; systematics;

    Abstract : Lactobacillus is a heterogeneous bacterial genus comprising at present 91 species. The high species number often makes classification and identification difficult, especially as the taxonomy to a high degree has been based on phenotypical traits. READ MORE

  4. 2. Impact of the gut microflora on the digestive system in the suckling rat

    Author : Frida Fåk; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; probiotics; prebiotics; antibiotics; lactobacilli; bacteria; intestinal permeability; Small intestine; maturation; weaning; suckling;

    Abstract : The postnatal development of the gastrointestinal (GI) system in mammals is genetically programmed, but is, to an unknown extent, regulated by external factors such as the diet and the gut microflora. These factors can influence the growth of the GI tract, the age-related pattern of appearance of digestive enzymes and the decreased intestinal macromolecular permeability at gut closure, normally timed with weaning in young rodents.

  5. 3. Lactic acid bacteria fermentations in oat-based suspensions

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

    Abstract : 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. READ MORE

  6. 4. Probiotic Lactobacilli in the context of dental caries as a biofilm-mediated disease

    Author : Pamela Hasslöf; Christina Stecksén Blicks; Svante Twetman; Peter Lingström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caries prevention; co-aggregation; dental caries; growth inhibition; mutans streptococci; probiotic lactobacilli; re-colonization; odontologi; Odontology;

    Abstract : Background: The World Health Organization defines probiotics as ‘live microorganisms which, when administered in adequate amounts, confer a health benefit to the host’. Traditionally, probiotic microorganisms have been used to prevent or treat gastrointestinal tract diseases. READ MORE

  7. 5. Fermented probiotic beverage based on quinoa : Functionality, hygiene, and health effects

    Author : Pamela Rosario Canaviri Paz; Avdelningen för livsmedel och läkemedel; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quinoa grains; Fermentation; Lactic acid bacteria; Probiotics; Food safety; Starter culture; Polyphenol compounds; Microbiota composition; Functional food; Gut microbiota;

    Abstract : White quinoa grains were used as a source of novel beneficial microorganisms and as a matrix for development of a fermented plant-based drink. Studies on the quinoa grain microbiota were performed by applying spontaneous fermentation to allow isolation of autochthonous Lactiplantibacillus strains with potential to be used as starter cultures.
