    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Aspergillus niger; beta-mannosidase; alpha-galactosidase; purification; hydrolysis; cloning; galactoglucomannan; expression; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : Galactoglucomannan and galactomannan are among the most abundant plant polysaccharides in nature. The central enzymes involved in their degradation, i.e., endo-1,4-beta-mannanase (beta-mannanase, EC 3. LÄS MER

  3. 12. Metabolic Engineering of Central Carbon Metabolism in Saccharomyces cerevisiae The contribution of systems biology to physiological studies

    Författare :Marta Papini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fermentation technology; Metabolic engineering; RNA-sequencing; Saccharomyces cerevisiae; DNA microarrays; 13Cbased flux analysis; system biology; Scheffersomyces stipitis;

    Sammanfattning : Saccharomyces cerevisiae is one of the most well characterized yeast of large industrial interest due to several attractivefeatures such as its capability to efficiently convert glucose into ethanol and carbon dioxide at high flux, its amenabilityto genetic modification and the presence of extensive knowledge databases. For these reasons, it is often considered asuitable cell factory for the production of different classes of compounds. LÄS MER

  4. 13. Dissolved organic matter in lakes : Chemical diversity and continuum of reactivity

    Författare :Alina Mostovaya; Lars Tranvik; Colin Stedmon; Uppsala universitet; []
    Nyckelord :dissolved organic matter; DOM; dissolved organic carbon; DOC; PARAFAC; reactivity continuum model; ultrahigh resolution mass spectrometry; FT-ICR-MS; organic matter characterization; decomposition kinetics; baseline metabolism; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Sammanfattning : Dissolved organic matter (DOM) is the largest pool of organic carbon in aquatic systems and an important component of the global carbon cycle. Large amounts of DOM are decomposed within lakes, resulting in fluxes of CO2 and CH4 to the atmosphere. LÄS MER

  5. 14. Physiology of Escherichia coli in batch and fed-batch cultures with special emphasis on amino acid and glucose metabolism

    Författare :Ling Han; KTH; []
    Nyckelord :escherichia coli; amino acids; glycine; quorum sensing; metabolic switch; metabolite po9ols; carbon balance; outer membrne; lipopolysaccharide; batch culture;

    Sammanfattning : The objective of this work is to better understand themetabolism and physiology ofEscherichiacoli(W3110) in defined medium cultures with thelong-term goal of improving cell yield and recombinant proteinproductivity.The order of amino acid utilization inE. colibatch cultures was investigated in a medium with16 amino acids and glucose.

  7. 15. Factors influencing the metabolism of inorganic arsenic in humans

    Författare :Anna-Lena Lindberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Arsenic; AS3MT; Gender differences; GSTO1; Metabolism; Methylation; MTHFR; Nutrition; Polymorphisms;

    Sammanfattning : Inorganic arsenic (iAs), a naturally occurring drinking water contaminant, is a potent human carcinogen and toxicant. It is believed that in humans, as well as in most mammals, inorganic arsenic is biotransformed via reduction and methylation using one-carbon metabolism with S-adenosyl methionine (SAM) as methyl donor, and is excreted mainly in urine as dimethylarsinate (DMA) and methylarsonate (MA) as well as some unmethylated iAs (arsenate (As(V)) and arsenite (As(III)).
