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

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

   Sammanfattning : 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.

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

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

   Sammanfattning : 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. LÄS MER

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

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

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

7. 5. Production, purification and characterization of antibacterial biomolecules from an alkaliphilic Bacillus

   Författare :Abolghasem Danesh; Bioteknik; []
   Nyckelord :;

   Sammanfattning : Forty alkaliphiles, which were isolated from samples collected in Eastern Africa, have been screened for production of antibacterial compounds. One of these isolates, Bacillus halodurans B20, was able to produce a prominent amount of antibacterial activity against a Gram-positive bacteria on agar plates [paper I] and selected for further study.
