    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.

  6. 4. Development of novel tools for prevention and diagnosis of Porphyromonas gingivalis infection and periodontitis

    Author : Sravya Sowdamini Nakka; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicin; Biomedicine;

    Abstract : Periodontitis is a chronic infectious disease causing inflammation and destruction of tooth-supporting structures eventually leading to tooth loss. Periodontitis is induced by different subgingival microorganisms in combination with an excessive and dysregulated immune-inflammatory response against this microbial challenge. READ MORE
