  1. 1. Evaluation of Novel Probiotics Acting on Seaweed Biomass

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

    Författare :Tushar Kaushik; [2021]
    Nyckelord :Seaweed; Alaria escuenta; Probiotics; Lactic acid bacteria; Biotechnology; Technology and Engineering;

    Sammanfattning : Fermentation is a technique which has been employed for the preservation of food since time immemorial. With a growing population comes the challenge of providing accessible and nutritious food and at the same time adapting a sustainable approach to achieve the desired target. LÄS MER

  3. 2. Algae hydrocarbons designed for bio-based lubricants

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elin Sjöhag; [2020]
    Nyckelord :Microalgae; macroalgae; lubricant; alginate; grease; Mikroalger; makroalger; smörjmedel; alginat; förtjockningsmedel;

    Sammanfattning : Smörjmedel är en nödvändighet för maskiner för att minska slitage och energiförbrukning. Dock är över 95% av de använda smörjmedlen i dag fossilbaserade. Smörjmedel baserade på vegetabiliska oljor finns tillgängliga men har ofta en lägre oxidativ stabilitet och sämre lågtemperaturegenskaper än deras fossilbaserade motsvarigheter. LÄS MER

  4. 3. Värdeskapande av koldioxid frånbiogasproduktion : En kartläggning över lämpliga CCU-tekniker för implementeringpå biogasanläggningar i Sverige

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Nils Broman; [2020]
    Nyckelord :carbon dioxide; Carbon capture and utilization; CCU; Carbon capture and storage; CCS; Carbon capture; utilization and storage; CCUS; Carbon dioxide utilization; biogas plant; biogas production; Carbon sinks; micro algae; Power to gas; liquid CO2; paris agreement; UNFCCC; Purification CO2; Upgrading CO2; amino scrubber; liquid scrubber; Cryogenic scrubber; contaminants biogas production; substrates used for biogas production; biogas upgrading technique review;

    Sammanfattning : Carbon dioxide from biogas production is currently considered to be without value and isbecause of this released into the atmosphere in the biogas upgrading process. The residualgas is a potential carbon source and can create value in the biogas manufacturing process. LÄS MER

  5. 4. Long-chain polyunsaturated fatty acid production by microalgae

    Kandidat-uppsats, SLU/Dept. of Food Science

    Författare :Ida Collinius; [2016]
    Nyckelord :micro algae; LC-PUFA; eicosanoids;

    Sammanfattning : Long chain polyunsaturated fatty acids (LC-PUFA) are essential to humans and needs to be consumed through the diet instead of production in the body. LC-PUFAs are in this report be categorized into omega-3 and omega-6 fatty acids. The aim of this study was to focus on LC-PUFAs that can be produced by species of microalgae of commercial interests.

  7. 5. The life cycle and developmental phases of Cambrian-Ordovician organic-walled microfossils from Kolguev Island, Arctic Russia.

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Magdalena Pazio; [2016]
    Nyckelord :Saharidia fragilis; Prasinophyceae algae; life cycle; acritarchs; Saharidia fragilis; Prasinophyceae; livscykel; acritarch;

    Sammanfattning : Light microscopy studies of collections of late Cambrian/Early Ordovician organic-walled microfossils, informally called acritarchs, provide the observations on phenotypic traits that are comparable to Modern microalgae and make possible recognition of various developmental stages in their complex life cycle. The exceptionally preserved Saharidia fragilis microfossils show the internal body within the vesicle and the formation of the fringe and pylome, the opening for releasing of the daughter cells from the phycoma-like cyst.
