1. 1. The Last Urban Frontier : Commodification of Public Space and the Right to the City in Insurgent Hong Kong

   Författare :Elton Chan; Sociologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public space; commodification; protest; right to the city; Hong Kong;

   Sammanfattning : This thesis explores the production and transformation of public spaces in Hong Kong, a city that is steeped in neoliberal ideals and has seen substantial deterioration in terms of democratic rights and freedoms in recent years. As a result of the expansion of neoliberal capitalism, commodification of urban space has not only exacerbated, but also become more far-reaching and indiscriminate. LÄS MER

3. 2. Metabolic engineering strategies to increase n-butanol production from cyanobacteria

   Författare :Josefine Anfelt; Elton P. Hudson; Mathias Uhlén; Patrik R. Jones; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyanobacteria; metabolic engineering; biofuels; butanol; synthetic scaffold; CRISPRi; solvent tolerance; Bioteknologi; Biotechnology;

   Sammanfattning : The development of sustainable replacements for fossil fuels has been spurred by concerns over global warming effects. Biofuels are typically produced through fermentation of edible crops, or forest or agricultural residues requiring cost-intensive pretreatment. LÄS MER

4. 3. Adaptations and constraints associated with autotrophy in microbial metabolism

   Författare :Johannes Asplund Samuelsson; Elton P. Hudson; Adil Mardinoglu; Costas D. Maranas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autotrophy; Carbon fixation; CO2 fixation; Calvin cycle; CBB cycle; Bacteria; Archaea; Prokaryotes; Cyanobacteria; Synechocystis; E. coli; Comparative genomics; Metabolic engineering; Microbial metabolism; Machine learning; Systems biology; Ribosome profiling; Kinetic modeling; Enzyme kinetics; Metabolic models; Pathway enumeration; Biosynthesis pathways; Metabolomics; Metabolite concentrations; Thermodynamics; Autotrofi; Kolfixering; CO2-fixering; Calvincykeln; CBB-cykeln; Bakterier; Arkéer; Prokaryoter; Cyanobakterier; Synechocystis; E. coli; Jämförande genomik; Metabolisk ingenjörskonst; Mikrobiell metabolism; Maskininlärning; Systembiologi; Ribosomprofilering; Kinetisk modellering; Enzymkinetik; Metaboliska modeller; Syntesvägsuppräkning; Biosyntesvägar; Metabolomik; Metabolitkoncentrationer; Termodynamik; Bioteknologi; Biotechnology;

   Sammanfattning : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. LÄS MER

5. 4. Synthetic biology approaches for improving production of fatty acid-derived compounds in cyanobacteria

   Författare :Ivana Cengic; Elton P. Hudson; Mathias Uhlén; Annegret Wilde; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyanobacteria; metabolic engineering; surface display; CRISPRi; fatty alcohols; fatty acid synthesis; aldehyde deformylating oxygenase; Bioteknologi; Biotechnology;

   Sammanfattning : The environmental consequences associated with the use of fossil-sourced fuels and chemicals have brought with it a realization that future development must move in a more sustainable direction. Currently available biofuels or renewably produced chemical, such as bioethanol or biodiesel, are produced from microbial fermentation of sugar-rich crops or by chemical conversion of natural oils or fats.

7. 5. On thermodynamic and kinetic constraints in autotrophic metabolism

   Författare :Markus Janasch; Elton P. Hudson; Bas Teusink; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; autotrophic metabolism; cyanobacteria; microbial metabolic engineering; computational systems biology; biochemical thermodynamics; kinetic modelling; Bioteknologi; Biotechnology;

   Sammanfattning : Earth has entered a new geological epoch, the Anthropocene, defined by humanity’s impact on the environment with increased emissions of CO2 due to burning of fossil resource as a major contributor. To ensure a sustainable future, humanity has to move towards a circular economy, where released CO2 is re-captured and turned into resources. LÄS MER
