  1. 1. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

    Författare :Rong Cao; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

    Sammanfattning : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. LÄS MER

  3. 2. 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.

  4. 3. Antifungal properties of dairy propionibacteria

    Författare :Helena Lind; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Today global agriculture is facing major challenges. The world's population is growing rapidly and we need to meet the increasing need for food with new strategies, including environmentally sustainable practices. Production must be enhanced with optimised resource utilisation and improved storage and distribution techniques. LÄS MER
