  1. 16. CRISPR based technologies for high-throughput metabolic engineering of yeast

    Author : Christos Skrekas; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cloning; Saccharomyces cerevisiae; enrichment; metabolic engineering; selection; library; screening; CRISPR; directed evolution;

    Abstract : The yeast Saccharomyces cerevisiae is a commonly used microorganism for metabolic engineering applications since it has a very well-studied metabolism and it can be easily genetically modified. This led to its use as a cell factory for the production of a wide variety of industrially relevant chemicals such as fuels, cosmetics and food additives. READ MORE

  2. 17. ω-Transaminase in Biocatalysis : Methods, Reactions and Engineering

    Author : Karim Engelmark Cassimjee; Per Berglund; Wofgang Kroutil; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Biocatalysis offers an alternative to classic chemistry by using enzymes, the protein catalysts of Nature, for production of fine chemicals. Evolution has created enzymes capable of catalysis at moderate temperature of a specific reaction in the presence of a plethora of compounds in the aqueous cell environment. READ MORE

  3. 18. Open-Loop Optimal Control of Chromatographic Separation Processes

    Author : Anton Sellberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chromatography; Modelling; Optimal Control; Parameter Estimation;

    Abstract : Chromatography is an important separation process for several industries due to its ability to separate components with similar physical properties, which are difficult to separate otherwise. This method may also give high product purity, which is necessary for production of biopharmaceuticals and fine chemicals. READ MORE

  4. 19. Enzymatic Reduction of Ketones

    Author : Magnus Carlquist; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inhibition; flavonoids; anthracyclines; human carbonyl reductase 1; kinetic resolution; Asymmetric bioreduction; bicyclic diketones; Saccharomyces cerevisiae; Escherichia coli; AKR; SDR;

    Abstract : Methods have been studied for the production of chiral alcohols, which are of importance in organic synthesis of pharmaceuticals, agro-chemicals and fragrances, etc., through the enzymatic or microbial reduction of ketones. READ MORE

  5. 20. Cellulose Nanofibril-based Hybrid Materials : Eco-friendly design towards separation and packaging applications

    Author : Luis Valencia; Aji Mathew; Olli Ikkala; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; hybrid materials; membranes; aerogels; separation; food packaging; Materials Chemistry; materialkemi;

    Abstract : Nanocellulose has been lately considered as the “Holy-Grail” in the design of sustainable materials due to its bio-origin and an unprecedented combination of prominent features, including good mechanical properties, anisotropy and versatile surface chemistry. In addition, nanocellulose in the form of cellulose nanofibrils, can adopt variable structures and morphologies depending on the processing technique, such as aerogels, films and monoliths. READ MORE
