  1. 1. Clostridium difficile : epidemiology and antibiotic resistance

    Författare :Torbjörn Norén; Erik Bäck; Lars G. Burman; Roland Möllby; Örebro universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Clostridium difficile; antibiotic resistance; epidemiology; Medicine; Medicin; Medicin; Medicine;

    Sammanfattning : Clostridium difficile is a spore-forming toxin-producing intestinal bacterium abundant in soils and waters. This pathogen relies on increased growth by a disturbed intestinal microflora and the production of two cytotoxins, toxin A and toxin B, which may cause anything from mild self-limiting C. LÄS MER

  3. 2. Analysis and engineering of central metabolism in Clostridium thermocellum

    Författare :Teun Kuil; Antonius J. A. van Maris; Ruud Weusthuis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; biofuels; ethanol; atypical glycolysis; pyrophosphate; phosphofructokinase; thermodynamic driving force; redox cofactor balancing; amino acid secretion; chaotropicity; hexose utilization; laboratory evolution; metabolic engineering; Biotechnology; Bioteknologi;

    Sammanfattning : To mitigate climate change, greenhouse gas emissions must be reduced to net-zero in 2050 requiring a drastic transition in today´s energy sector. To achieve this goal, the use of biofuels produced from lignocellulosic feedstocks, including agricultural and forestry residues, is expected to play an important role. LÄS MER

  4. 3. Toxin production in clostridium difficile

    Författare :Sture Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Clostridium difficile is a is a Gram potential human pathogen. It causing symptoms ranging from mild C. difficile associated diarrhea (CDAD) to severe inflammation of the colon including pseudomembranous colitis and fulminant colitis. Over 300 000 and about 10 000 CDAD episodes are diagnosed annually in the USA and Sweden, respectively. LÄS MER

  5. 4. Lactobacillus reuteri in health and disease

    Författare :Gabriela Sinkiewicz; Malmö högskola; []
    Nyckelord :breast milk; lactobacilli; Lactobacillus reuteri; probiotics; Bifidobacteria; clostridium; faeces; Gingivitis; oral health;

    Sammanfattning : People have exploited fermentation by lactobacilli for centuries as a means of preparing and preserving foods. Several different bacterial species are today used as probiotic bacteria in different products both for human and animal applications. LÄS MER

  7. 5. Insights into the metabolism of Clostridium thermocellum for cellulosic ethanol production

    Författare :Johannes Yayo; Antonius J. A. van Maris; Richard Sparling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; ethanol; glucose; fructose; amino acids; pyrophosphate; chaotropicity; thermodynamic driving force; laboratory evolution; chemostats; metabolic engineering; Biotechnology; Bioteknologi;

    Sammanfattning : The societal goal of reaching net-zero CO2 emissions requires development of integrated biorefineries to produce biomass-derived fuels and chemicals. For sustainable second-generation bioethanol production, consolidated bioprocessing with the thermophile Clostridium thermocellum is regarded as a promising concept in view of the microorganism’s native ability to efficiently degrade plant cell wall material.
