  1. 6. Genetics of Tetrapyrrole Synthesis in Gram-Positive Bacteria

    Författare :Per Johansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; siroheme; tetrapyrrole synthesis; Bacillus subtilis; Bacillaceae; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The organization and regulation of genes for tetrapyrrole synthesis were studied in low G+C Gram-positive bacteria. Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. LÄS MER

  3. 7. Engineering of staphylococcal surfaces for biotechnological applications

    Författare :Henrik Wernérus; KTH; []
    Nyckelord :affibody; albumin binding protein; Bacterial surface display; cell immobilisation; bioremediation; combinatorial protein engineering; flow cytometry; Gram-positive; metal-binding; staphylococcal protein A; Staphylococcus carnosus; Staphylococcus xylo;

    Sammanfattning : The engineering of bacterial surfaces has in recent yearsattracted a lot of attention with applications in manydifferent areas of bioscience. Here we describe the use of twodifferent surface display systems for the gram-positivebacteria Staphylococcus carnosus and Staphylococcus xylosus invarious biotechnological applications. LÄS MER

  4. 8. Studies on Haemproteins of Gram-positive Bacteria - Implications as Antibacterial Drug Targets

    Författare :Peter Kjelgaard; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteriology; virology; mycology; Mikrobiologi; Microbiology; heme; Truncated hemoglobins; cytochrome c maturation; cytochrome bd; ResB; bakteriologi; virologi; mykologi;

    Sammanfattning : With the discovery of antibiotics, several diseases that were previously lethal is today readily cured, or so we thought. Some degree of resistance to one or several antibiotics can be found among many strains of clinical important bacteria. LÄS MER

  5. 9. Staphylococcal surface display for protein engineering and characterization

    Författare :John Löfblom; Stefan Ståhl; Henrik Wernérus; K. Dane Wittrup; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; affibody; combinatorial library; epitope mapping; Gram-positive bacteria; protein engineering; staphylococcal surface display; Molecular biology; Molekylärbiologi;

    Sammanfattning : Even though our understanding of mechanisms such as protein folding and molecular recognition is relatively poor, antibodies and alternative affinity proteins with entirely novel functions are today generated in a routine manner. The reason for this success is an engineering approach generally known as directed evolution. LÄS MER

  7. 10. On the development of low level resistance in gram-positive and gram-negative bacteria after antibiotic exposure

    Författare :Gunilla Rådberg; Signe Ringertz; Östergötlands Läns Landsting; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Resistance has been found to develop and spread via several mechanisms against virtually all clinically available antimicrobial agents. Increasing use of antibiotics has been shown to correlate to increasing incidence of bacterial resistance. LÄS MER
