  2. 1. An Alkaline Active Cyclodextrin Glycosyltransferase from an Alkaliphilic Bacillus agaradhaerens

    Author : Rita Martins; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloning; characterization; purification; 16S rRNA gene analysis; screening; alkaliphiles; soda lakes; Bacillus agaradhaerens; cyclodextrins; cyclodextrin glycosyltransferase; alpha-amylase family; sequencing; immobilization; Biotechnology; Bioteknik;

    Abstract : Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. READ MORE

  5. 3. Exploring glycoside hydrolase family 5 (GH5) enzymes

    Author : Yang Wang; Ines Ezcurra; Henrik Aspeborg; Henrik Stålbrand; Torkel Berglund; KTH; []
    Keywords : GH5; glycoside hydrolase; subfamily classification; mannans; polysaccharides; mannanases; cell wall; GH5; glykosidhydrolas; subfamiljklassificering; mannaner; polysackarider; mannanaser; cellvägg; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : In 1990, the classification of carbohydrate-active enzymes (CAZymes) was introduced by the scientist Bernard Henrissat. According to sequence similarity, these enzymes were separated into families with conserved structures and reaction mechanisms. READ MORE

  6. 4. Combining Metabolic Engineering and Synthetic Biology Approaches for the Production of Abscisic Acid in Yeast

    Author : Maximilian Otto; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; Botrytis cinerea; cell factory; abscisic acid; synthetic biology; biosensor; sesquiterpenoid; standardization; Saccharomyces cerevisiae;

    Abstract : Nature presents us with a myriad of complex and diverse molecules. Many of these molecules prove to be useful to humans and find applications as pharmaceuticals, biofuels, agrochemicals, cosmetic ingredients or food additives. One highly promising natural product with a broad range of potential applications is the terpenoid abscisic acid (ABA). READ MORE

  7. 5. Use of feruloyl esterases for chemoenzymatic synthesis of bioactive compounds

    Author : Io Antonopoulou; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : Feruloyl esterases (FAEs, EC 3.1.1.73) represent a subclass of carboxylic acid esterases that under normal conditions catalyze the hydrolysis of the ester bond between hydroxycinnamic acids (ferulic acid, sinapic acid, caffeic acid, p-coumaric acid) and arabinose residues in plant cell walls.
