    Sammanfattning : β-N-methylamino-L-alanine (BMAA) is a neurotoxic non-proteinogenic amino acid produced naturally by cyanobacteria, diatoms and dinoflagellates and it has been detected in samples from fresh and marine water from all over the world. It can bioaccumulate in fish and shellfish, and has a potential to biomagnify in a terrestrial food chain. LÄS MER

    Sammanfattning : Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. LÄS MER

  7. 25. Biobased production of succinic acid by Escherichia coli fermentation

    Författare :Christian Andersson; Gen Larsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : 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). The present thesis illustrates different aspects of biobased succinic acid production by a metabolically engineered E. coli strain. LÄS MER
