  1. 6. Fermentation of wheat starch hydrolysate by Lactococcus lactis: Factors affecting product formation

    Author : Karin Hofvendahl; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nutrients; temperature; pH; optical isomers; maltose; wheat; starch hydrolysate; Lactococcus lactis; lactic acid; SSF; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Lactic acid exists as two optical isomers, D- and L-lactic acid. For the production of biodegradable poly-lactic acid an optically pure product is desirable, but a racemate of known and constant ratio can also be used. Lactic acid can be produced either synthetically or fermentatively. READ MORE

  2. 7. 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

  3. 8. Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive

    Author : Victor Ibrahim; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Laccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product.

  4. 9. 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

  5. 10. Succinic acid production using metabolically engineered Escherichia coli

    Author : Christian Andersson; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). To date, the primary emphasis has been placed on the replacement of oil for transportation fuels. READ MORE
