1. 1. An insight towards food-related microbial sets through metabolic modelling and functional analysis

   Författare :Simonas Marcisauskas; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; RAVEN; gut; systems biology; comparative genomics; Kluyveromyces marxianus; bile acids; genome-scale metabolic model; next-generation sequencing; transcriptomics; thermotolerance;

   Sammanfattning : The dietary food digestion depends on the human gastrointestinal tract, where host cells and gut microbes mutually interact. This interplay may also mediate host metabolism, as shown by microbial-derived secondary bile acids, needed for receptor signalling. Microbes are also crucial in the production of fermented foods, such as wine and dairy. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

4. 3. Function and regulation of the Yeast Mig1 repressor

   Författare :Jonas Östling; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; glucose repression; Mig1; zinc finger protein; Saccharomyces cerevisiae; Kluyveromyces marxianus; Snf1; Biokemi; Biochemistry; Biokemi; molekylär cellbiologi; Molecular Cellbiology;

   Sammanfattning : Glucose repression is a global regulatory response in the yeast Saccharomyces cerevisiae. Thus, in the presence of glucose, the preferred carbon source, expression of many genes encoding proteins required for metabolism of other carbon sources are turned off.An important mediator of glucose repression is the Mig1 repressor.

5. 4. A systems biology understanding of protein constraints in the metabolism of budding yeasts

   Författare :Iván Domenzain Del Castillo Cerecer; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gene regulation; omics analysis; enzyme capacity; metabolism; systems biology; stress adaptation; genome-scale modeling; metabolic engineering;

   Sammanfattning : Fermentation technologies, such as bread making and production of alcoholic beverages, have been crucial for development of humanity throughout history. Saccharomyces cerevisiae provides a natural platform for this, due to its capability to transform sugars into ethanol. LÄS MER

7. 5. Yeast biotechnology for nutritional improvements of fermented cereal-based foods - Phytate degradation and folate production

   Författare :Andreas Hellström; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mineral availability; phosphate; togwa; starter culture; Yeast; food fermentation; phytase; phytate; folate;

   Sammanfattning : Anaemia is a serious public health problem in nearly all developing countries. It has negative consequences on cognitive and physical development of children, reduces work capacity in adults, and increases the risk of maternal and child mortality. LÄS MER
