  2. 1. Synthetic biology approaches for improving production of fatty acid-derived compounds in cyanobacteria

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

    Abstract : 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.

  4. 2. Fatty Acyl Reductases and Fatty Acyl Desaturases. Deciphering the biosynthesis of species-specific moth female sex pheromones from common fatty acids

    Author : Åsa Hagström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Moth; pheromone; insect; evolution; fatty acyl desaturase; fatty acyl reductase; endoplasmic reticulum; fatty acid biosynthesis; GFP; heterologous expression; phylogeny; cell factory; lepidoptera;

    Abstract : Moths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland.

  5. 3. The Use of Supercritical Fluids to Reduce the Number of Phases in Catalytic Hydrogenation: The Reaction of Fatty Acid Methyl Esters to Fatty Alcohols

    Author : Sander van den Hark; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fatty alcohols; single phase; deactivation; mass transport; phase reduction; supercritical fluids; hydrogenation; propane; kinetics; catalysis;

    Abstract : Supercritical fluids have unique properties - between those of liquids and gases - making them attractive reaction media. In this study, propane was used to change a heterogeneous catalyst from being substrate-covered in gas-liquid hydrogenation reactions into hydrogen-covered in our experiments. READ MORE

  6. 4. Fatty acid reductases (FAR): Insights into the biosynthesis of fatty alcohols in plants and bacteria

    Author : Thuy Doan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Primary fatty alcohols are present in all phyla, where they serve various unique biological functions, either in structural materials or biochemical compounds. Fatty alcohols and derivatives provided by living organisms are also important feedstock for the oleochemical and lubricant industries. READ MORE

  7. 5. Bioactive Carbohydrates in Vining Peas (Pisum sativum) - Variation in alpha-galactoside content and the colonic fermentation of sugar alcohols

    Author : Jimmy Ekvall; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-galactosides; raffinose family oligosaccharides; Näringslära; Nutrition; short-chain fatty acids; colonic fermentation; myo-inositol; sorbitol; xylitol; sugar alcohols; blanching; maturity; cultivar; Pisum sativum;

    Abstract : The composition of the colonic microflora is essential for the health of the human host. To be able to survive, the microflora is dependent of a continuous supply of substrate. In this respect dietary fibre and other indigestible carbohydrates, of which the consumption in affluent societies is generally low, are of great importance. READ MORE
