  2. 1. 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.

  4. 2. Plantaricins as a novel group of antibacterial compounds and enhancers of antibiotics

    Author : Amani Musa; Hazem Khalaf; Torbjörn Bengtsson; Elena Vikström; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteriocin; antimicrobial peptide; plantaricin; antibiotic resistance; PLNC8 αβ; ESKAPE pathogens;

    Abstract : Antibiotics have revolutionized medicine, however, the rapid development of an-tibiotic resistance among bacteria is diminishing their efficacy. Antimicrobial pep-tides produced by Lactobacillus plantarum, i.e., plantaricins, are considered prom-ising alternatives to antibiotics against infections. READ MORE

  5. 3. Novel methods for diagnosis and treatment of periodontal disease

    Author : Anna Svärd; Torbjörn Bengtsson; Tülay Lindberg; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; inflammation; Porphyromonas gingivalis; gingipains; biosensing; gold nanoparticles; antimicrobial treatment; NC8;

    Abstract : Periodontitis is an inflammatory condition affecting tooth-supportive structures, the periodontium. Gingival tissues respond to biofilm formation by initiating an inflammatory process. READ MORE

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

    Author : Sravya Sowdamini Nakka; Torbjörn Bengtsson; Hazem Khalaf; Fariba Nayeri; Johanna Lönn; Tülay Lindberg; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; Porphyromonas gingivalis; anti-P. gingivalis antibodies; surface plasmon resonance; PLNC8 αβ; proliferation; growth factors.; Biomedicin; Biomedicine;

    Abstract : Periodontitis is a chronic inflammatory disease caused by exaggerated host immune responses to dysregulated microbiota in dental biofilms leading to degradation of tissues and alveolar bone loss. Porphyromonas gingivalis is a major periodontal pathogen and expresses several potent virulence factors. READ MORE

  7. 5. 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
