2. 1. Food Cultures in Sápmi : An interdisciplinary approach to the study of the heterogeneous cultural landscape of northern Fennoscandia AD 600–1900

   Author : Markus Fjellström; Gunilla Eriksson; Kerstin Lidén; Lars Liedgren; Marianne Skandfer; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Food Culture; Diet; Mobility; Iron Age; Middle Ages; Sápmi; Sámi Archaeology; Reindeer Domestication; Stable Isotope Analysis; Elemental Analysis; Repatriation; Reburial; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

   Abstract : The aim of this thesis is to highlight the heterogeneous cultural landscape in Sápmi through the study of food. By studying food and the choices of specific foodstuffs in Sápmi AD 600–1900, a greater understanding can be gained on the history of this area during the period. READ MORE

4. 2. Microbiological food safety of cheese produced in Swedish small-scale dairies : characteristics, growth and enterotoxin production of Staphylococcus aureus

   Author : Åsa Rosengren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The number of small-scale dairies in Sweden has increased during the past decade. Current agricultural policy encourages such small-scale production and various ways to help producers have been proposed. Combining traditional cheese making and good product safety is a challenge, since several human pathogens pose a hazard in the products. READ MORE

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

   Author : Rong Cao; Teknisk mikrobiologi; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Stress induced virulence of Staphylococcus aureus and Listeria monocytogenes

   Author : Nikoleta Zeaki; Teknisk mikrobiologi; []
   Keywords : ;

   Abstract : Control of the dissemination of pathogens in the food production chain is an on-going process with new challenges emerging as pathogenic bacteria evolve and express enhanced virulence characteristics. Staphylococcus aureus and Listeria monocytogenes are two notorious pathogens responsible for staphylococcal food poisoning (SFP) and listeriosis: a foodborne intoxication and an infectious disease respectively.

7. 5. Bacillus Cereus. Adhesion Ability to Biological and Non-Biological Surfaces, Enterotoxins, Characterization

   Author : Annika Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; characterization; Bacillus cereus; spores; adhesion; enterotoxin;

   Abstract : The organism investigated in this thesis was Bacillus cereus, which is important as a food spoilage organism and as a pathogen. The adhesion of endospores to and the removal of endospores from siliconized glass surfaces were investigated to increase the knowledge of adhesion mechanisms and to improve the removal of endospores from surfaces.
