  1. 6. Expression and Mutagenesis studies of Candida antactica lipase B

    Författare :Johanna C. Rotticci-Mulder; KTH; []
    Nyckelord :Protein expression; Candida antarctica lipase B; Pichia pastoris; site-directed mutagenesis; fermentation; selection;

    Sammanfattning : Recombinant Candida antarctica lipase B was successfullyproduced in the methylotropic yeast Pichia pastoris. Thespecific activities of Candida antarctica lipase B produced inPichia pastoris and commercial Candida antarctica lipase B fromNovozymes were the same. In shake-flask cultivations theexpression levels were about 25 mg L-1. LÄS MER

  3. 7. The Effects of Mutation and Selection on the Rate and Pattern of Molecular Evolution in Birds

    Författare :Sofia Berlin; Hans Ellegren; Adam Eyre-Walker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; substitution rate; diversity; selection; male mutation bias; birds; Genetik; Genetics; Genetik;

    Sammanfattning : By comparing sequence diversity and divergence on sex chromosomes one can study how the rate of evolution in affected by mutation and/or selection. The rate of mutation in male biased, meaning that relatively more mutations are created in the male germ line than in the female. LÄS MER

  5. 9. Splice site selection in Saccharomyces cerevisiae pre-mRNA splicing

    Författare :B G Mattias Luukkonen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pre-mRNA splicing is the process by which intervening sequences (introns) are removed from the coding sequences (exons) resulting in a mature messenger-RNA (mRNA). Splicing takes place in a large ribonucleoprotein complex termed the spliceosome, composed of several protein components and the five small nuclear RNAs (snRNAs) U I, U2, U4, U5 and U6. LÄS MER

  7. 10. Potential Use of Aquifer Thermal Energy Storage System in Arid Regions

    Författare :Qais Al-Madhlom; Jan Laue; Nadhir Al-Ansari; Sabbar Abdullah Saleh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer thermal energy storage system; ATES; site selection; seepage velocity; aquifer vulnerability; DRASTIC; arid regions; ArcMap GIS; Soil Mechanics; Geoteknik;

    Sammanfattning : After the Oil Crises in 1973, which meant higher energy costs, the world started to look for other sources of energy. This led to the development of renewable energy techniques. Because of the intermittent nature of renewable energy, storage systems were also developed. LÄS MER
