  1. 1. Mass Spectrometry of Biologically Active Small Molecules : Focusing on polyphenols, alkaloids and amino acids

    Författare :Zdeněk Spáčil; Leopold L. Ilag; Frantisek Turecek; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LC-MS; LDI; Mass spectrometry; HPLC; UHPLC; polyphenols; phenolic acids; BMAA; Separation methods; Separationsmetoder; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The foci of this dissertation are on advanced liquid chromatography (LC) separation and mass spectrometry (MS) techniques for the analysis of small bioactive molecules. In addition to discussing general aspects of such techniques the results from analyses of polyphenols (PPs), alkaloids and amino acids published in five appended studies are presented and discussed.

    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lingonberry; brown bean; flavonoids; phenolic acids; dietary fiber; HPLC-UV MS; atherosclerotic plaque; plasma lipid; gut microbiota; short-chain fatty acids; trimethylamine N-oxide; Apoe- - mice; lingon; bruna bönor; flavonoider; fenolsyror; kostfiber; HPLCUV MS; aterosklerotisk plaketter; plasmalipid; tarm-mikrobiota; kortkedjiga fettsyror; trimetylamin N-oxid; Apoe- - möss; Livsmedelsvetenskap; Food Science;

    Sammanfattning : Consumption of berries and pulses can protect against atherosclerosis and other metabolic diseases, by modulating plasma lipid profile, gut microbiota, and microbiota-dependent metabolites. These nutritional benefits are often attributed to high content of polyphenols (flavonoids and phenolic acids) and dietary fiber. LÄS MER

  5. 4. Ethanol from Lignocellulose - Fermentation Inhibitors, Detoxification and Genetic Engineering of Saccharomyces cerevisiae for Increased Resistance

    Författare :Simona Larsson; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; detoxification; S. cerevisiae; lignocellulose; inhibition; phenolic compounds; laccase; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars, and then fermenting the hydrolysate with the yeast Saccharomyces cerevisiae. Hydrolysis using dilute sulphuric acid has advantages over other methods, however, compounds which inhibit fermentation are generated during this kind of hydrolysis. LÄS MER
