1. 1. Wood hydrolysate Barriers

   Författare :Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; xylan; hemicellulose; layered silicates; oxygen barrier; packaging; film; coaing; birch.;

   Sammanfattning : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today.

3. 2. Wood Hydrolysate for Renewable Products

   Författare :Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Ann Cornell; Louise Staffas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wood hydrolysate; hemicellulose; oxygen permeability; PALS; film; coating; CMC; chitosan; HSP; Polymer chemistry; Polymerkemi;

   Sammanfattning : Renewable biomass has been used by mankind for a long time for different purposes, from simply food to industrial products. Among a large family of polysaccharides, hemicellulose is non-edible but has shown a potential in many industrial fields such as medicine, agriculture and packaging. LÄS MER

4. 3. Fermentation of undetoxified dilute acid lignocellulose hydrolysate for fuel ethanol production

   Författare :Tomas Brandberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrolysate; lignocellulose; Saccharomyces cerevisiae; nitrogen limitation; microaerobic conditions; cell recirculation; continuous fermentation; Mucor indicus; ethanol; cell retention;

   Sammanfattning : Important aspects of ethanol production from undetoxified dilute acid lignocellulose hydrolysate are covered in this thesis, which primarily focuses on the use of Saccharomyces cerevisiae (Baker's yeast) as the biocatalyst. Nine different strains of S. LÄS MER

5. 4. Genetic engineering of Yarrowia lipolytica for the sustainable production of food oils

   Författare :Oliver Konzock; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triacyclglycerols; RNA-seq; tolerance; cocoa butter; hydrolysate; yeast; desaturase; filamentation;

   Sammanfattning : The human population and its demand for food oils is constantly growing. However, increasing food oil production currently requires the deforestation of mostly tropical rainforests to allow the plantation of oil crops. LÄS MER

7. 5. Fermentation of wheat starch hydrolysate by Lactococcus lactis: Factors affecting product formation

   Författare :Karin Hofvendahl; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nutrients; temperature; pH; optical isomers; maltose; wheat; starch hydrolysate; Lactococcus lactis; lactic acid; SSF; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Lactic acid exists as two optical isomers, D- and L-lactic acid. For the production of biodegradable poly-lactic acid an optically pure product is desirable, but a racemate of known and constant ratio can also be used. Lactic acid can be produced either synthetically or fermentatively. LÄS MER
