  4. 2. Protected Lignin Biorefining: Fundamental Insights on Lignin Reactivity

    Author : Maria Karlsson; Martin Lawoko; Åsa Emmer; Olena Sevastyanova; John Ralph; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainability; lignin; biorefinery; cyclic organosolv extraction; preserved structure; NMR; MALDI-TOF MS; Hållbarhet; lignin; bioraffinaderi; cyklisk organosolv extraktion; bevarad struktur; NMR; MALDI-TOF MS; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The potential to utilize lignin, which constitutes as much as 15-30% of the biomass, needs further evaluation. In the transition towards a bioeconomy, lignin has the potential to replace fossil-based phenols. Attempts to valorize the available technical lignins are ongoing; however, that lignin suffers from molecular heterogeneity. READ MORE

  5. 3. Modeling for Quality and Safety in Biopharmaceutical Production Processes

    Author : Karin Westerberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process modeling; chromatography; quality by design; robustness; process control;

    Abstract : To design efficient and safe biopharmaceutical production processes, understanding the process and how it is affected by changes in the process conditions is essential. Experimental data form the basis of this understanding which can be enhanced by modeling and simulations of the physical and chemical processes known to control the process. READ MORE

  6. 4. Multifunctional carbohydrate-based soft materials from cereal by-products

    Author : Secil Yilmaz Turan; Francisco Vilaplana; Rosana Moriana; Amparo Jiménez Quero; Anna Ström; KTH; []
    Keywords : wheat bran; corn bran; hemicellulose; arabinoxylan; ferulic acid; subcritical water extraction; acetylation; films; hydrogels; crosslinking; regeneration; antioxidant activity; vetekli; majskli; hemicellulosa; arabinoxylan; ferulsyra; subkritisk vattenextraktion; acetylering; filmer; hydrogeler; tvärbindning; regeneration; antioxidant aktivitet; Bioteknologi; Biotechnology;

    Abstract : Cereal production generates large quantities of by-products every year, which still remain underutilized. The hemicellulose fractions from cereal by-products are anticipated to play an important role in tomorrow's sustainable and bio-based circular economy. READ MORE

  7. 5. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

    Author : Evelina Kulcinskaja; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

    Abstract : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. READ MORE
