  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. 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.

  6. 4. Microbial polymers produced from residual biomass: exploring the potential of different microbes

    Author : Luis Alejandro Romero Soto; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microbial polymers; Exopolysaccharides; Polyhydroxybutyrates; residual biomass; agrowaste; pretreatment; hydrolysates; optimisation;

    Abstract : Microorganisms are important sources of diverse intracellular and extracellular biopolymers havingdifferent functions such as serving as carbon and energy reserves, or as protective layers around the cells in theform of capsules and/or biofilms. They have also found use in foods, medicine and other industrial applications. READ MORE

  7. 5. Production of Ectoines and Poly(3-Hydroxybutyrate): High Cell-Density Cultivation of Halomonas Boliviensis

    Author : Hector Guzmán; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poly 3-hydroxybutyrate ; hydroxyectoine; ectoine; Halomonas boliviensis; compatible solutes; Fed-batch cultivation;

    Abstract : This thesis reports a study involving the use of Halomonas boliviensis, a moderate halophile, for production of biopolyester poly(3-hydroxybutyrate) (PHB) and compatible solutes ectoine and hydroxyectoine through high cell-density cultivation comprising fed-batch cultures. PHB is a biodegradable plastic produced by bacteria as energy reserve and can potentially be used as a replacement of fossil based plastic. READ MORE
