  2. 6. Algal-Bacterial Photobioreactors for the Degradation of Toxic Organic Pollutants

    Author : Raul Munoz; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; symbiosis.; nutrient removal; heavy metals removal; Algal-bacterial systems photobioreactors; toxic organic pollutants;

    Abstract : The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. READ MORE

  4. 7. Fungal and bacterial contributions to decomposition in terrestrial and aquatic ecosystems

    Author : Margarida Soares; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fungi; bacteria; microbial carbon use efficiency; litter decomposition; priming effect; heavy metal stress;

    Abstract : Microbial decomposers process a great majority of net primary production in the biosphere and regulate carbon (C) and nutrient cycling. Microbial communities are extremely diverse and often disregarded from global C-cycling models, but one strategy to overcome this challenge is to focus on the major decomposer groups: fungi and bacteria.

  5. 8. Host responses to malaria and bacterial co-­infections

    Author : Maria Nelson; Johan Normark; Sven Bergström; Anna Fahlgren; Olle Stendahl; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Plasmodium; Malaria; Borrelia; S. pneumoniae; Co-infection; Immunology; Metabolomics;

    Abstract : The two main causes of child mortality and morbidity in Africa are malaria and invasive bacterial diseases. In addition, co-infections in sub-Saharan Africa are the rule rather than the exception. However, not much is known about the host-pathogen interaction during a concomitant infection or how it affects the outcome of disease. READ MORE

  6. 9. Bacterial gene expression inhibition with antisense peptide nucleic acids

    Author : Rikard Dryselius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Regulated gene expression is widely useful for gene function studies and as a means to control genes important in disease. There are many methods for regulating the expression of genes, and one approach is to use antisense oligonucleotides that bind complementary mRNAs to inhibit translation. READ MORE

  7. 10. Links Between Structure and Function of Heterotrophic Aquatic Bacterial Communities

    Author : Silke Langenheder; Lars Tranvik; Eva Lindström; David Kirchman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; heterotrophic bacteria; dissolved organic matter; diversity; community composition; ecosystem functioning; salinity; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Heterotrophic bacteria utilize dissolved organic matter, and the carbon flow through an ecosystem depends on the fractions of the utilized carbon that is either respired or transferred to higher trophic levels. The major aim this thesis is to investigate 1) the relationship between composition and functioning in heterotrophic bacterioplankton communities and 2) the influence of environmental conditions on both parameters.
