2. 1. Malic acid production by Aspergillus oryzae

   Author : Christoph Knuf; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; C4 dicarboxylic acids; Aspergillus oryzae; systems biology; fermentation; malic acid; metabolic engineering;

   Abstract : Malic acid is a C4 dicarboxylic acid which is used as an acidulant in food and beverages. It isalso considered as a bio-building block to replace petrochemically derived compounds in thepost oil era. This organic acid can be biotechnologically derived from fermentation usingrenewable feedstocks as carbon source. READ MORE

4. 2. Impact of Cultivation Parameters on Cell Physiology of Limosilactobacillus reuteri

   Author : Nikhil Seshagiri Rao; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; probiotics; L. reuteri; oxygen; fermentation; heterogeneity; morphology; flow cytometery; freeze-drying; stress tolerance; Online flow cytometry; k-means clustering; fatty acids; defined minimal media; pre-formulation hold time;

   Abstract : Optimisation of cultivation conditions in the industrial production of probiotics is crucial to reach a high-quality product with high probiotic functionality. The production process includes a fermentation step to produce biomass, accompanied by centrifugation to concentrate the cells. READ MORE

5. 3. On yeasts from traditional fermented foods - Characterization, phytate degradation, strain improvement and applications

   Author : Linnea Qvirist; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytase; Saccharomyces cerevisiae; Phytate; Pichia kudriavzevii; Phenotypic Characterization; Goat Milk; Food Fermentation; Kluyveromyces marxianus; Yaghnob Valley;

   Abstract : Plant materials naturally contain minerals of iron, zinc and calcium. However, plants also contain a compound called phytic acid, which can chelate the minerals and form insoluble complexes. Minerals from plant foods are unavailable for intestinal uptake when they are bound in phytate complexes. READ MORE

6. 4. Evaluation of biosensors and flow cytometry as monitoring tools in lignocellulosic bioethanol production

   Author : Raquel Perruca Foncillas; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; Biosensors; Flow cytometry; Bioethanol production; Lignocellulosic biomass; Xylose; Strain engineering; Lignocellulosic ethanol; Lignocellulosic inhibitors; Furfural;

   Abstract : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. READ MORE

7. 5. Used but not Sensed - The Paradox of D-xylose Metabolism in Saccharomyces cerevisiae

   Author : Karen Ofuji Osiro; Teknisk mikrobiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; saccharomyces cerevisiae; sugar sensing signalling; D-Xylose; XR XDH; GFP biosensor; cAMP PKA; Snf3p Rgt2p; SNF1 Mig1p; flow cytometry;

   Abstract : The realization that the extraction and combustion of fossil fuels is having serious effects on the environment and the climate, together with the ever-growing need for fuels, has led to the development of the concept of the biorefinery. Biorefineries are refineries in which fossil resources, such as oil, are replaced by renewable biomaterials to produce biofuels and biochemicals. READ MORE
