  1. 1. Effect of nutrient limitation in chemostat cultures on amino acid excretion in Clostridium thermocellum

    Uppsats för yrkesexamina på avancerad nivå, KTH/Industriell bioteknologi

    Författare :Chonticha Phongsawat; [2019]
    Nyckelord :Biotechnology; ethanol; Clostridium; chemostat; nitrogen;

    Sammanfattning : Introduction: Clostridium thermocellum is considered a model organism forconsolidated bioprocessing, due to its ability to hydrolyze lignocellulosicbiomass more efficiently than many other organisms and to produce ethanol.In order to meet the industrial requirements of ethanol yield and titer, metabolicengineering efforts have been made resulting in a strain that successfullydisplays increased ethanol yield with reduced amount of some byproducts.

  3. 2. Structure and function of a bacterial redox sensor.

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Marwaa Ahmad; [2016]
    Nyckelord :Rex protein; Microscale thermophoresis MST ; dissociation constant Kd ; protein science; proteinvetenskap; Biology and Life Sciences; Chemistry;

    Sammanfattning : Gram-positive bacteria e.g. Streptomyces coelicolor [8], Bacillus subtilis [43] and Staphylococcus aureus [40] contain a novel sensor for the nicotinamide adenine dinucleotide (NAD) redox balance that functions as a transcriptional repressor called Rex (redox). Rex plays a key role in regulating genes in energy metabolism. LÄS MER

  4. 3. MFA för att öka produktiviteten av 3HB av rekombinant E.coli

    Master-uppsats, KTH/Skolan för bioteknologi (BIO)

    Författare :Gustav Sjöberg; [2014]
    Nyckelord :;

    Sammanfattning : Computer modeling has gained increasin attention as a quick method to investigate the effect of genetic changes on the metabolic networks of well-known organisms. This study has focused on the use of genome scale metabolic modelin of Escherichia coli metabolism to find ways of improving 3-hydroxybutyric acid (3HB) productivity. LÄS MER

  5. 4. The effect of redoxmodulation on osteoclastogenesis

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Sara Witte; [2010]
    Nyckelord :morfologi;

    Sammanfattning : During osteoclast differentiation and bone resorption the redox status in the cell display a decrease in reduction and a shift to an oxidized state. Structure, metabolism and function are some of the extensive changes that cells undergo during differentiation which alters both the extra- and intracellular redox environment. LÄS MER

  7. 5. Mineralization rates of organic matter in freshwater sediments when different electron acceptors dominate.

    Magister-uppsats, Institutionen för tematisk utbildning och forskning

    Författare :Catrin Samuelsson; [2004]
    Nyckelord :Interdisciplinary studies; Mineralization rate; Organic matter; Electron acceptor; Microbial metabolism; Methane; Carbon dioxide; Stångån; TVÄRVETENSKAP;

    Sammanfattning : Microbial decomposition of organic matter in aquatic environments plays an important role in natural fluxes of methane and carbon dioxide because the gases are end-products in microbial energy metabolism of organic matter. Microbial metabolism depends on the use of electron donors and electron acceptors in redox reactions that generate energy for growth and maintenance. LÄS MER
