2. 21. Lactic acid production: extractive fermentation in aqueous two-phase systems

   Author : Jordi Planes; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gel excludion chromatography; polyethylenimine; ethylene oxide propylene oxide; phase forming polymers; aqueous two-phase systems; extractive fermentation; Lactococcus; Lactobacillus; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; mycology; Microbiology;

   Abstract : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.

4. 22. Early-life gut microbiota and breast milk oligosaccharides in relation to childhood immune maturation and allergy

   Author : Ylva Margareta Sjögren; Eva Sverremark-Ekström; Outi Vaarala; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; allergy; infant; gut microbiota; human milk oligosaccharides; Bifidobacterium; Lactobacillus; Bacteroides fragilis; Clostridium difficile; family size; secretory IgA; toll like receptor; Immunology; Immunologi; immunologi; Immunology;

   Abstract : Atopic allergy is the most common chronic disease among children in the developed world. This high prevalence could be associated with low microbial exposure. The early gut microbiota appears to be important for immune maturation. READ MORE

5. 23. Lactobacillus in semi-hard cheese and their use as adjunct cultures

   Author : Martin Antonsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Adjunct culture; NSLAB; Non-starter Lactic acid bacteria; Cheese ripening; Model cheese; Lactobacillus paracasei; Cheese; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : The microflora of Herrgård cheese produced at three dairies was compared after three and six months maturation. The microflora of cheeses from two of the dairies was dominated by a spontaneous microflora of Lactobacillus after three months of ripening, while starter bacteria still dominated in cheese from the third dairy after six months.

6. 24. On Lactobacillus plantarum 299v, bacterial translocation and intestinal permeability

   Author : Peter Mangell; Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacterial translocation; permeability; intestinal microflora; Kirurgi; orthopaedics; P-selectin; ortopedi; traumatologi; leukocyte recruitment; Lactobacillus plantarum 299v; traumatology; Surgery; colon resection;

   Abstract : The gastrointestinal tract harbours a huge load of bacteria which exerts important biological functions to maintain health. In certain conditions the relation between commensal bacteria and pathogens may be set off balance, with an increase in number of pathogens and risk of bacterial translocation (BT). READ MORE

7. 25. Lactobacillus mediated targeting of gastrointestinal pathogens

   Author : Kasper Krogh Andersen; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The mucosal membranes of the gastrointestinal, genitourinary and respiratory tract are the main targets for infection in the human body and are repeatedly challenged by pathogens. Passive immunization using delivery of antibodies at the mucosal membrane may thus provide a new first line of defense against these pathogens. READ MORE
