1. 1. Acrylamide in Potato Crisps - A Three-year Study on Swedish-grown Potatoes

   Författare :Gunilla Viklund; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Potato varieties; Asparagine; Acrylamide; Potato crisps; Reducing sugars;

   Sammanfattning : Acrylamide, a probable human carcinogen, has been found at mg/kg levels, in heat-treated carbohydrate-rich foods. Acrylamide is formed via the Maillard reaction as a result of the reaction between the amino acid asparagine and reducing sugars (glucose and fructose). LÄS MER

3. 2. Biochemical conversion of biomass to biofuels : pretreatment–detoxification–hydrolysis–fermentation

   Författare :Venkata Prabhakar Soudham; Jyri-Pekka Mikkola; Christer Larsson; Tom Birger Granström; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic materials; Ionic liquids; Pretreatment; Inhibitors; Detoxification; Ferrous sulfate and hydrogen peroxide; reducing agents; alkaline treatments; Hydrolysis; Fermentation; Biofuels; biokemi; Biochemistry;

   Sammanfattning : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. LÄS MER

4. 3. Industrial challenges in the use of Saccharomyces cerevisiae for ethanolic fermentation of lignocellulosic biomass

   Författare :Violeta Sanchez Nogue; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; Pentose fermentation; Evolutionary engineering; Acetic acid; pH; Short-term adaptation; Resident yeast; Spent sulphite liquor fermentation; Dekkera bruxellensis; Lactobacillus pentosus.;

   Sammanfattning : The sustainable production of ethanol from lignocellulosic biomass requires the combination of efficient hydrolysis and complete fermentation of all the monomeric sugars present in the raw material. The present work was aimed at tackling some of the major challenges that will be encountered in commercial-scale ethanol production using Baker’s yeast, Saccharomyces cerevisiae, the preferred microorganism for the fermentation step.

5. 4. Lytic Polysaccharide MonoOxygenases; their role for lignocellulose depolymerization and production of (functional) biobased compounds

   Författare :Madhu Muraleedharan Nair; Paul Christakopoulos; Ulrika Rova; Mats Sandgren; Francisco Vilaplana; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : Increased environmental concerns over petroleum-based products triggered the quest to find a sustainable alternative for fuels, chemicals etc. Lignocellulose biomass, due to its abundance, is considered as one of the most promising sustainable sources for the production of fuels and chemicals, while replacing the traditional petroleum resources.

7. 5. Depolymerization of Lignocellulose by Lytic Polysaccharide MonoOxygenases

   Författare :Madhu Nair Muraleedharan; Paul Christakopoulos; Ulrika Rova; Mats Sandgren; Johan Larsbrink; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : Lignocellulose biomass is considered as one of the most potential and sustainable sources for the production of value-added chemicals and fuels while replacing the traditional petroleum resources. In a biorefinery, by employing biochemical conversion processes,cellulose present in the biomass is broken down into monomeric sugars which can belater converted into fuels or chemicals. LÄS MER
