  1. 21. Studies of the Effects of Industrial Processing on Fruit

    Författare :Uno Viberg; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; antioxidants; invertase; thawing; blackcurrant; strawberry; fruit; berry; Livsmedelsteknik;

    Sammanfattning : The industrial production of preserves includes several unit operations which all affects sensorial properties as well as the nutritional value of the final product. Thawing is a crucial unit operation, since then both chemical and physical changes take place. LÄS MER

  3. 22. β-Mannoside hydrolases from clan A – Structural enzymology, subsite engineering and transglycosylation

    Författare :Anna Rosengren; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-mannosidase; β-mannanase; enzymology; kinetics; MALDI-TOF MS; protein engineering; protein structure; subsite organisation; transglycosylation;

    Sammanfattning : β-Mannoside hydrolases are enzymes that are involved in conversion of the major soft-wood hemicellulose O-acetyl-galactoglucomannan, an important renewable biomass resource. They belong to clan A of glycoside hydrolases and share a common (β/α)8-TIM barrel fold. LÄS MER

  4. 23. Thermostable glycosidases and glycosynthases as biocatalysts in green chemistry applications

    Författare :Tania Pozzo; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green chemistry; 3D sturcture; Glycosyl hydrolases; Glycosynthases; Alkyl glucosides; Oligosaccharides; Flavonoids;

    Sammanfattning : The constant need to develop environmental friendly processes using renewable raw materials and to reduce harmful waste production motivates the present investigation focusing on biocatalyst development for enzymatic synthesis, a biotechnological approach in the field of green chemistry. At first, structural functional experiments were made for a β-glucosidase from T. LÄS MER

  5. 24. Evolution of Yeast Respiro-Fermentative Lifestyle and the Underlying Mechanisms Behind Aerobic Fermentation

    Författare :Arne Hagman; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crabtree effect; aerobic fermentation; respiro-fermentation; ethanol production; yeast; central carbon metabolism; evolution of alternative lifestyles;

    Sammanfattning : Under aerobic conditions, most yeasts such as Kluyveromyces lactis, prefer the respiratory pathway and some, such as Saccharomyces cerevisiae prefer less energy efficient fermentative pathway for their energy metabolism. These two metabolic strategies are also known as Crabtree negative and Crabtree positive respectively, and the evolution of the latter has lately been explained by the “make-accumulate-consume” life strategy.

  7. 25. Salt-inducible kinases in adipose tissue

    Författare :Johanna Sernevi Säll; Proteinfosforylering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; salt-inducible kinase; SIK; SIK2; fettväv; fettceller; insulinsignalering; glukosupptag; fetma; insulinresistens; salt-inducible kinase; SIK; SIK2; adipose tissue; adipocytes; insulin signalling; glucose uptake; obesity; insulin resistance;

    Sammanfattning : Obesity, insulin resistance and type 2 diabetes (T2D) are metabolic diseases that increase rapidly in the modern society. The underlying mechanisms are complex and involve both environmental and genetic factors. Adipose tissue is an important organ for maintaining whole body energy homeostasis. LÄS MER
