  2. 6. Interplay between bacteria and host epithelial cells

    Author : Lisa Maudsdotter; Ann-Beth Jonsson; Cindy Grove Arvidson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbial-cell interaction; Adherence; Infection; Lactic acid bacteria; Antimicrobial peptides; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Bacterial pathogens have developed multiple ways of manipulating host cell functions to exploit the host environment. We found that interactions with epithelial cells increase the resistance of the human pathogen Neisseria meningitidis to the antimicrobial peptide LL-37. READ MORE

  4. 7. Modelling and Optimisation of Integrated Biotechnical Processes -Application to the Fermentative Production of Lactic Acid from Wheat Flour

    Author : Christina Åkerberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; economy; wheat flour; starch; lactic acid; kinetics; simulation; modelling; optimisation; Kemiteknik och kemisk teknologi;

    Abstract : Biotechnical processes are often integrated to increase productivity and yield. It is difficult to predict the effects of process integration and to find optimum conditions for the process. A valuable tool for the evaluation of a complete process is mathematical modelling. READ MORE

  5. 8. Fluoride concentration in plaque and saliva and its effects on oral ecology after intake of fluoridated milk

    Author : Kristina Engström; Svante Twetman; Lars G Petersson; Göran Dahllöf; Umeå universitet; []
    Keywords : children; enamel; demineralisation; fluoride; lactic acid; laser fluoroscense; milk; plaque; saliva; salivary bacteria; odontologi; Odontology;

    Abstract : According to WHO, the addition of fluoride to milk could be considered as an alternative to water fluoridation for community-based caries prevention in childhood. School-based schemes in developing as well as industrial countries have demonstrated substantial benefits on oral health, but there are limited data available on the local events in the oral cavity after consumption of fluoridated milk.

  6. 9. Production, Purification and Characterization of Antimicrobial Biomolecules from Potential Probiotic Lactic Acid Bacteria

    Author : Sahar Deraz; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactobacillus; Bioteknik; Biotechnology; Livsmedelsteknik; Food and drink technology; bacteriocin purification.; inhibitory activity; Bacteriocin; antimicrobial protein;

    Abstract : Development and optimization of the production of lactic acid bacteria (LAB) and their attendant 'natural' inhibitors as biopreservatives to control undesirable bacteria currently remains a primary focus of several laboratories involved in research concerning food safety and quality. Strategies utilized to study incorporation of biopreservatives into food include either direct use of LAB-strains or use of a biopreservative preparation in the form of previously fermented product or use of semipurified, purified, or chemically synthesized bacteriocins.

  7. 10. The effect of honeybee-­specific lactic acid bacteria on american foulbrood disease of honeybees

    Author : Sepideh Lamei; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The honeybee, Apis mellifera, is one of the most economically important pollinators and highly valued for its honey and wax production. Managed honeybees occupy an increasingly critical role in agricultural productivity and food security. READ MORE
