  1. 1. Discovery and investigation of glycoside hydrolase family 5 enzymes with potential use in biomass conversion

    Author : Yang Wang; Henrik Aspeborg; Ines Ezcurra; Jerry Ståhlberg; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; plant cell wall; biomass; hemicellulose; mannans; glycoside hydrolase; subfamily classification; Arabidopsis; mannanase; transglycosylase; enzymatic characterization.; Biotechnology; Bioteknologi;

    Abstract : Glycoside hydrolases (GHs) cleave glycosidic bonds in glycoconjugates, oligosaccharides and polysaccharides such as cellulose and various hemicelluloses. Mannan is a major group of hemicelluloses. READ MORE

  2. 2. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

    Author : Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Abstract : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. READ MORE

  3. 3. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides

    Author : Maria Henriksson; Tuula Teeri; KTH; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; glycosynthase; Pichia pastoris; fed-batch fermentation; expanded-bed adsorption; Plant biotechnology; Växtbioteknik;

    Abstract : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. READ MORE

  4. 4. Plant cell-inspiredmicrocontainers: Fabrication, Characterization and Applications

    Author : Thomas Paulraj; Anna Justina Svagan; Daniel Crespy; KTH; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Biomimetic materials have been inspiring mankind since a longtime for applications in a variety of fields. In particular, the production of lipidbasedvesicles have aided in our understanding of a variety of functions in animalcells, and also served as e.g. drug delivery systems and bioreactors. READ MORE

  5. 5. Microbial Fuel cells, applications and biofilm characterization

    Author : Adolf Krige; Paul Christakopoulos; Sebastià Puig; Luleå tekniska universitet; []

    Abstract : Since the 1900’s it has been known that microorganisms are capable of generating electrical power through extracellular electron transfer by converting the energy found organic compounds (Potter, 1911). Microbial fuel cells (MFCs) has garnered more attention recently, and have shown promise in several applications, including wastewater treatment (Yakar et al. READ MORE
