  5. 8. Physiology of Industrially Relevant Bacteria: Freeze-drying tolerance of Lactobacillus reuteri and Pseudomonas chlororaphis and product formation of Lactococcus lactis metabolizing maltose

    Author : Johan Palmfeldt; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virologi; mykologi; Microbiology; bacteriology; virology; mycology; bakteriologi; Mikrobiologi;

    Abstract : When the metabolic activity of bacteria is exploited by the food and biotechnology industries, freeze-drying is commonly used to produce concentrated bacterial cultures with enhanced storage stability. The freeze-drying tolerance of the probiotic strain Lactobacillus reuteri and the biocontrol agent Pseudomonas chlororaphis has been characterized in this work. READ MORE

  6. 9. 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

  7. 10. Metabolic responses ofPseudomonas stutzeriandEscherichia colisubjected to starvation and surplus of carbon/energy substrates in bioreactors

    Author : Bo Xu; KTH; []
    Keywords : ;

    Abstract : Transient nitrite accumulation during anaerobicdenitrification is a widespread phenomenon for manydenitrifying bacteria includingPseudomonasstutzeri. Nitrate starvation caused the degradation ofthe second denitrifying enzyme nitrite reductase (NiR) inP.stutzeri. READ MORE
