  1. 1. Using Neural Networks to Predict Cell Specific Productivity in Bioreactors

    University essay from Umeå universitet/Institutionen för fysik

    Author : Frida Nordström; [2021]
    Keywords : machine learning; neural networks; nn; biopharma; sartorius; bioreactor; metabolic productivity; cell;

    Abstract : During production of certain biopharamaceutical drugs, cells are grown in a liquid mediainside bioreactors with the goal of producing a specic biomaterial that can be rened intoa drug. This project investigates whether the use of Neural Networks (NN) can decreasethe prediction error, in terms of Mean Squared Error (MSE), for 2 metabolic processes incells compared to current methods.

  3. 2. Optimizing Growth Conditions for Lactic Acid Bacteria

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lorenzo García Tejada; [2021]
    Keywords : Lactic Acid Bacteria; Optimization; Cell growth; Lactic acid production; Oxygen; Yeast extract; Wood hydrolysate; Poly-lactic acid; Chemical engineering; Technology and Engineering;

    Abstract : High production titers are paramount in lactic fermentation processes aimed towards poly lactic acid (PLA) manufacturing. Optimization of the fermentation stage is therefore essential for the viability of the process. READ MORE

  4. 3. Variability and regulation of the planktonic respiratory quotient in a eutrophic lake (Lake Vombsjön) in summer 2016

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Karla Münzner; [2017]
    Keywords : Physical geography and ecosystem analysis; biogeochemistry; bacterioplankton respiration; eutrophic lake; carbon cycling; Lake Vombsjön; Earth and Environmental Sciences;

    Abstract : Bacterial respiration and biomass growth are important processes for carbon cycling in freshwater ecosystems and bacterial respiration is often quantified from measured O2 concentrations by using a respiratory quotient (RQ=O2 consumed to produce CO2, in moles) of 1. Recent studies have shown, however, that RQs can vary a lot in different aquatic ecosystems (0. READ MORE

  5. 4. Size and Abundance of Late Pleistocene Reticulofenestrid Coccoliths from the Eastern Indian Ocean in Relation to Temperature and Aridity

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jeroen van Dijk; [2017]
    Keywords : coccoliths; abundance; biometry; circular polarized light microscopy; Late Pleistocene; Marine Isotope Stage 11; kokkoliter; mängder; biometri; cirkulär polariserat ljus; pleistocen; Marine Isotope Stage 11;

    Abstract : Measurements on coccolith abundance and mass can be used as a signal of primary productivity and pelagic calcification in response to environmental change. The Leeuwin Current (LC) is known to transport warm and low-salinity waters from the Indo-Pacific Warm Pool (IPWP) southwards along the coast of West Australia. READ MORE

  6. 5. Metabolic channeling for biofuel production : Co-localization of Pdc and Adh

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Isabel Moreno de Palma; [2017]
    Keywords : Bioethanol; Metabolic channeling; Synthetic biology; fusion of proteins; RNA scaffold; DNA scaffold; protein scaffold;

    Abstract : Enhancing productivity in bioprocesses, especially for biofuel production, is crucial for achieving an environmentally and economically sustainable biotechnology industry.Metabolic channelling occurs in nature when the intermediate between two consecutive enzymes in a pathway is directed from the first enzyme to the second avoiding diffusion in the cytosol.
