  1. 21. In silico analysis of microbial communities through constraint-based metabolic modelling

    Författare :Parizad Babaei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fermented food production; metagenomics; genome-scale metabolic model; community modelling; malnourishment; Microbial community; systems biology; lactic acid bacteria; gut microbiota; uniform randomised sampling;

    Sammanfattning : Microbial communities are involved in many vital biological processes from elemental cycles to sustaining human health. The bacterial assemblages are remarkably under-studied as they are reluctant to grow in the laboratory conditions. LÄS MER

  3. 22. Microbial biofilm communities associated with degradation of sprayed concrete in subsea tunnels

    Författare :Sabina Karacic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine environment; subsea tunnels; surface structure; biofilm; steel fibers; metagenomics.; microbially induced deterioration; amplicon sequencing; concrete;

    Sammanfattning : Deterioration of concrete leads to reduced structural strength implying high societal challenge with huge economic impact. In the Oslofjord subsea tunnel, complex microbial biofilm activity together with abiotic attack from saline groundwater are responsible for concrete matrix degradation and steel fiber corrosion.

  4. 23. When bioelectrochemical systems meet extremophiles, possibilities and challenges

    Författare :Gaofeng Ni; Mark Dopson; Bert Hamelers; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

    Sammanfattning : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. LÄS MER

  5. 24. Identification of novel antibiotic resistance genes through large-scale data analysis

    Författare :Fanny Berglund; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; hidden Markov model; carbapenemases; antibiotic resistance; big data; carbapenemases;

    Sammanfattning : Antibiotic resistance is increasing worldwide, and is considered a serious threat to public health by e.g. the World Health Organization. Antibiotic resistance genes are hypothesized to originate from harmless bacteria in and around us, from where they are horizontally transfered into human pathogens. LÄS MER

  7. 25. New antibiotic resistance genes and their diversity

    Författare :Fanny Berglund; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; β-lactamases; hidden Markov model; antibiotic resistance; carbapenemases; big data; tetracycline resistance;

    Sammanfattning : Antibiotic resistance is increasing worldwide and is considered a severe threat to public health. Often, antibiotic resistance is caused by antibiotic resistance genes, of which many are hypothesized to have been transferred into human pathogens from environmental bacteria. LÄS MER
