2. 1. Valorization of Low Value Organic Waste by the use of Black Soldier Fly Larvae – Bioconversion of Sludge from the Pulp and Paper Industry

   Author : Robert Norgren; Anders Jonsson; Olof Björkqvist; William Hogland; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainable sludge management; bioconversion; insect protein;

   Abstract : The current economic system is not sustainable, as it is based on a linear flow of resources from extraction, production, use and disposal. The linear flow of resources must be replaced with a circular flow where waste is seen as a resource. READ MORE

4. 2. Towards bacterial valorization of low molecular weight lignin

   Author : Krithika Ravi; Avdelningen för kemiteknik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas putida; Microbacterium sp.; Guaiacol; Syringate; Kraft lignin; Bioconversion; Biorefineries;

   Abstract : Lignin is one of the major constituents in lignocellulosic biomass and is the mostabundant source of renewable aromatics on terrestrial ecosystems. The workcarried out in this thesis concerns bacterial conversion of low molecular weightlignin. READ MORE

5. 3. Biosynthesis of capsaicinoids by recombinant Saccharomyces cerevisiae

   Author : Nina Muratovska; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capsaicinoids; nonivamide; baker’s yeast; Capsicum; Saccharomyces cerevisiae; Pseudomonas putida; lignin-derived substrates; vanillin aminotransaminase; reductive amination; vanillylamine; N-Acyltransferase; CoA-ligase; amide; whole-cell bioconversion; TRPV1 receptor; ion channel; calcium dye Fluo-4; flow cytometry;

   Abstract : Throughout history, people have used products from different microorganisms and plants for many medicinal and nutritional applications. Chilli peppers have been used for spicing up food, but also for their pharmacological properties. READ MORE

6. 4. Base-catalyzed depolymerization of kraft lignin for valuable chemical production

   Author : Kena Li; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kraft lignin; Depolymerization; CFR; Membrane filtration; Guaiacol; Vanillin; bioconversion;

   Abstract : Lignin is one of the three predominant biopolymers that make up plants together with cellulose and hemicellulose, and it is the only plant component that is based on aromatic units. The industrial kraft pulping process generates large amounts of lignin, which is currently used to generate heat for the process. READ MORE

7. 5. Four carbon oxychemicals from renewable resources

   Author : Adam Marschall Jaros; Christian Andersson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. READ MORE
