  1. 1. Lackticka, Ganoderma lucidum : produktion och användningsområden

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Oskar Larsson; Filippa Goh; [2023]
    Nyckelord :Medicinalsvamp; sekundära metaboliter; produktion;

    Sammanfattning : Ganoderma lucidum (Lackticka) är en saprofytisk svamp i ordningen Polyporales som livnär sig på att bryta ned ved av hårda lövträd. Utseendet kan variera en aning men kännetecknas främst av sin hårda, glansiga, röda fruktkropp som vanligtvis växer i en halvmåneform. LÄS MER

  3. 2. Valorising spent coffee grounds : An assessment of possibilities in the municipality of Stockholm

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emma Westling; [2023]
    Nyckelord :Food waste hierarchy; spent coffee grounds; circular economy; economic assessments; waste valorisation; Matavfallshierarki; Kaffesump; Cirkulär ekonomi; ekonomisk bedömning; avfallsvalorisering;

    Sammanfattning : Circular economy is an economic model that is gaining more and more attention, themodel aims to close production chains by recirculate waste into the system as newraw material. Spent coffee grounds are a waste that has great potential to becomenew products since the spent coffee ground contains many valuable substances suchas polysaccharides, polyphenols, and lipids.

  4. 3. Protein-based hydrogel electrolytes for stretchable Zn-ion batteries

    Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Författare :Lovisa Byström; [2023]
    Nyckelord :Hydrogel; gelatin; kappa-carrangeenan; Zn-ion battery; Kemisk biologi; Kemisk biologi;

    Sammanfattning : Stretchable aqueous-based Zn-ion batteries have shown promise as a sustainable and safe energy storage system for wearable electronics used in healthcare, sports, soft robotics, and prosthetics. A battery consists of the active electrode, electrolyte, current collector, and encapsulation. LÄS MER

  5. 4. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
    Nyckelord :hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

    Sammanfattning : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. LÄS MER

  7. 5. Characterization of ulvan polysaccharide degrading enzymes from Wenyingzhuangia fucanilytica

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Författare :Erik Apelqvist; [2022]
    Nyckelord :Enzyme; Enzymatic characterization; Recombinant protein producaiton; Protien purification; E. coli; W. fucanilytica; Transformation; Overexpression; Seaweed; Ulvan; Polysaccharides; biotechnology; Biology and Life Sciences;

    Sammanfattning : The aim of this thesis was to fully characterize the enzyme WFp-105, including bioinformatic analysis, structural modeling, full activity and stability characterization and product determination. As well as for the enzyme WFp-37; optimize protein production in regard to expression strains and cultivation temperature, analyzing the genomic context as well as performing an initial activity detection.
