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

    Författare :Sweta Singh; [2024]
    Nyckelord :lactic acid bacteria; solid-state fermentation; Alaria esculenta; Saccharina latissima; seaweed fermentation; biotechnology; Technology and Engineering;

    Sammanfattning : Fermentation has played a vital role in human history, offering solutions for food preservation, culinary diversity, and the creation of diverse and flavorful foods and beverages. Its importance continues today, both in traditional practices and in modern industrial applications. LÄS MER

  3. 2. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Gustav Larsson; [2023]
    Nyckelord :organic solar cells; polymer; morphology; film; AFM;

    Sammanfattning : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

  4. 3. Algaform : en studie om möjligheterna att använda alger som material i produkter

    Kandidat-uppsats, Högskolan i Gävle/Industridesign

    Författare :Sebastian Hedin; [2023]
    Nyckelord :alger; materialdriven design; materialdriven; design; produkt; produktutveckling; industridesign; formgivning; ericsson; innovation; skörda alger; miljö; hållbarhet; hållbar; grönslick; algaform; 5g; idrott; elitidrott;

    Sammanfattning : I ett tidigare arbete har den snabbväxande fintrådiga algen grönslick undersökts som material i produkter. När algen kokas, pressas och torkas kan det hålla en form. Algafrom som materialet kallas är lätt, hårt och omformningsbart. LÄS MER

  5. 4. Method development of flow cytometry analysis of yeast and lactic acid bacteria viability for alcohol fermentation

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Megha Komahan; [2023]
    Nyckelord :Flow cytometry; yeast; lactic acid bacteria; fermentation; cell viability; applied microbiology; Technology and Engineering;

    Sammanfattning : The usage of yeast in conventional brewing techniques involving alcoholic fermentation is an age-old process. Analyzing the viability and obtaining physiological information regarding the microbial diversity of the fermentation samples plays a pivotal role in obtaining real-time information as well as developing a more efficient process design.
