  1. 21. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae

    Författare :Nina Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ethylene forming enzyme; Ethylene; respiration rate; Saccharomyces cerevisiae; cultivation; production; nitrogen metabolism; 2-oxoglutarate; enzyme engineering; metabolic modeling;

    Sammanfattning : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. LÄS MER

  2. 22. Vem formar den stategiska forskningen? Institutionell dynamik och anslagspolitisk utveckling i KK-stiftelsen

    Författare :Daniel Holmberg; Research Policy Institute (RPI); []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Strategic research; strategic research funding; research funding organization; higher education institutions; organizational institutionalist theory; The Knowledge Foundation;

    Sammanfattning : Research policy is increasingly linked to social needs and to some extent integrated with industrial and innovation policy. The strategic research policy that emerged in Sweden in the early 1990's resulted in the establishment of a new kind of research funding both in form and direction: strategic research foundations.

  3. 23. Microbial Synthetic Biology, Systems Metabolic Engineering and Enzyme Engineering for Advanced Microbial Biodiesel Production with Saccharomyces cerevisiae

    Författare :Juan Octavio Valle Rodriguez; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein rational engineering; wax ester synthase; hydrolase; advanced biofuel; fatty acid metabolism; directed evolution; chromosomal delta-integration;

    Sammanfattning : The continuous requirement of transportation biofuels has brought the necessity to establish alternatives permitting low-cost production of biodiesel while being environmentally friendly. Biodiesel production was achieved utilizing Saccharomyces cerevisiae by employing respective enzymes that catalyze the synthesis of fatty acid ethyl esters (FAEEs) based on fatty acyl-CoA molecules and ethanol.

  4. 24. Metabolic Engineering of Recombinant Protein Production by Saccharomyces cerevisiae

    Författare :Zihe Liu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recombinant protein production; genome sequencing; DNA microarray; insulin precursor; growth rate; UV mutation; yeast; anaerobic electron acceptor; secretory pathway; unfolded protein response; metabolic engineering; systems biology; α-amylase;

    Sammanfattning : The yeast Saccharomyces cerevisiae is a widely used cell factory for the production of fuels, chemicals, and it also provides a platform for the production of many heterologous proteins of medical or industrial interest. In this thesis, random and rational approaches, such as vector design, host engineering, fermentation analysis, UV Mutation, coupled with high-throughput systems biology techniques (including whole genomic sequencing, microarray analysis and flux analysis) and integrated analysis (Reporter feature technique), were employed to engineer cellular properties more effectively and purposefully to construct cell factories for protein production.

  5. 25. Enzymes for selective decoupling of woody biomass: From fundamentals to industrial potential

    Författare :Jenny Arnling Bååth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulose; glucuronoyl esterase; polysaccharide acetylation; carbohydrate esterase family 15; woody biomass; materials biorefinery; enzyme accessibility; lignin-carbohydrate bonds; mannanase; galactoglucomannan;

    Sammanfattning : The need for an economy based on renewable materials has resulted in growing interest in the use of woody biomass in a wider field of application. However, the chemical complexity of lignocellulose and the dense structure of wood pose challenges in its processing. LÄS MER
