    Sammanfattning : AbstractTransition from fossil- to bio-based economy is a critical step towards reduction of greenhouse gas emissions and climate change, and hence for achievement of sustainable communities and environment. In order to be fossil-free, the chemical and material industry is in need of carbon-neutral building blocks from renewable resources for the diverse array of products that are currently produced from olefins and aromatics.

  3. 42. Enhanced Enzymatic Hydrolysis of Lignocellulose in Bioethanol Production Substrate Interactions with Surfactants and Polymers

    Författare :Johan Börjesson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enzymologi; Penicillium brasilianum; SSF; Ethanol; Proteins; enzymology; Proteiner; Protease; Adsorption; PEG; Surfactant; Hydrolysis; Lignocellulose; Cellulase; Hypocrea jecorina; Trichoderma reesei; Cellulose;

    Sammanfattning : Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol.

    Sammanfattning : Insulin-regulated aminopeptidase (IRAP) has emerged as a potential new therapeutic target for treatment of cognitive disorders. Inhibition of the enzymatic activity facilitates cognition in rodents. LÄS MER

  5. 44. Glutaredoxin 3 from Escherichia coli : NMR structure analysis and structural aspects of the enzymatic mechanism

    Författare :Kerstin Nordstrand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The structure of Escherichia coli glutaredoxin 3 (Grx3) was investigated using NMR spectroscopy in combination with isotope labeling. Nearly complete sequence specific assignment were obtained for the reduced Grx3 using a 15N enriched protein sample. LÄS MER
