  2. 1. Poly (3-hydroxybutyrate) from a moderate halophile: production and modification for new applications

    Author : Marlene Munoz; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biopolymers; polyhydroxyalkanoates; polyhydroxybutyrate; moderate halophile; Halomonas boliviensis; fermentation; recovery; thermally induced phase separation; scaffolds; covalent modification; hydrophobic ion pairing; polyethylenemine; lysozyme.;

    Abstract : Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence replace these fossil based polymers in a large variety of applications. READ MORE

  4. 2. Novel Moderate Halophiles: Application of Halomonas boliviensis in Biopolyester Production

    Author : Jorge Quillaguaman; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; biopolymers; Polymer technology; poly b-hydroxybutyrate accumulation; moderate halophile; Halomonas boliviensis; Chromohalobacter sarecencis; Polymerteknik; Bioteknik;

    Abstract : The south-west Andean region of Bolivia has vast landscapes comprising salt deserts and dry lands interspersed with a number of saline lakes. Much of this region lies above 4000 m above sea level that allows the survival of limited and unique flora and fauna. READ MORE

  5. 3. Characterization and engineering of carbohydrate-active enzymes for biotechnological applications

    Author : Noor Hassan; Christina Divne; Eva Nordberg Karlsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; se conversion; galacto-oligosaccharides; thermostability; propeptide; Bioteknologi; Biotechnology;

    Abstract : Extremozymes are enzymes produced by microorganisms that live in extreme habitats. Due to their higher stability, extremozymes is attracting interest as biocatalysts in various industrial processes. In this context, carbohydrate-active extremozymes can be used in various processes relevant to the paper, food and feed industry. READ MORE

  6. 4. Culture-independent methods and high-throughput sequencing applied to evolutionary microbial genomics

    Author : Anders E. Lind; Thijs JG Ettema; Purificación López-García; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Single cell genomics; metagenomics; amplicon; archaea; haloarchaea; endosymbiosis; ciliate; hydrogenosome; tree reconciliation;

    Abstract : Culture-independent methods allow us to better understand the diversity of microorganisms on earth. By omitting the culturing step, we can gain access to species previously out of our reach.To better capture and understand the diversity of microorganisms, we have developed an alternative to 16S amplicon sequencing.

  7. 5. An alkaline active maltooligosaccharide forming alpha-amylase from Bacillus halodurans

    Author : Suhaila Hashim; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk teknik; Biochemical technology; differential scanning calorimetry; soda lakes; Bacillus halodurans; alkaliphile; á-amylase;

    Abstract : The East African Rift Valley contains a number of soda lakes, which represent some of the most stable, naturally occurring alkaline environments on earth. Alkaliphilic microorganisms found in these habitats have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values for industrial applications.
