  2. 1. Exploring glycoside hydrolase family 5 (GH5) enzymes

    Author : Yang Wang; Ines Ezcurra; Henrik Aspeborg; Henrik Stålbrand; Torkel Berglund; KTH; []
    Keywords : GH5; glycoside hydrolase; subfamily classification; mannans; polysaccharides; mannanases; cell wall; GH5; glykosidhydrolas; subfamiljklassificering; mannaner; polysackarider; mannanaser; cellvägg; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : In 1990, the classification of carbohydrate-active enzymes (CAZymes) was introduced by the scientist Bernard Henrissat. According to sequence similarity, these enzymes were separated into families with conserved structures and reaction mechanisms. READ MORE

  4. 2. Analysis of Genes and Proteins Involved in Wood Formation

    Author : Anders Winzell; Tuula Teeri; Alan Marchant; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : SAMMANFATTNING Vedbildning är en underliggande mekanism för så skilda områden som industri, boende och en hållbar miljö. Vedbildning sker i det vaskulära kambiet där organiserade celldelningar åtföljs av differentiering till specialiserade vedceller. READ MORE

  5. 3. Chemical Modification of Nanostructured Wood for Functional Biocomposites

    Author : Shennan Wang; Qi Zhou; Gustav Nyström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; nanostructured materials; nanocellulose; delignification; oxidation; crosslinking; amination; MOFs; transparent film; hydrogel; aerogel; biocomposites; mechanical properties; thermochromic materials; CO2 capture; protein immobilization.; Biotechnology; Bioteknologi;

    Abstract : Recently emerged top-down processing concept has provided new insights into the chemical modification of wood at the nanoscale. Nanostructured wood with naturally aligned cellulose microfibrils, cell wall nanoporosity, and precisely tuned chemical composition has opened up numerous possibilities for advanced design of functional materials.

  6. 4. Streptomyces sporulation - Genes and regulators involved in bacterial cell differentiation

    Author : Jessica Larsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Streptomyces coelicolor; venezuelae; morphological differentiation; WhiH; WhiA;

    Abstract : Streptomycetes are Gram-positive bacteria with a complex developmental life cycle. They form spores on specialized cells called aerial hyphae, and this sporulation involves alterations in growth, morphogenesis and cell cycle processes like cell division and chromosome segregation.

  7. 5. Role of TLR4 in Escherichia coli urinary tract infection

    Author : Patrik Samuelsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; mycology; Mikrobiologi; bakteriologi; serologi; transplantation; Microbiology; virology; bacteriology; Immunologi; serology; Immunology; Pathogen; Mucosa; P-fimbriae; Toll like receptor;

    Abstract : In this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. READ MORE
