  1. 1. Bacterial identification by the 16S rRNA gene

    Författare :Tobias Olofsson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Naturvetenskap; Natural science; mykologi; virologi; Mikrobiologi; mycology; virology; bacteriology; 16S rRNA; Microbiology; Identification; Bacteria; bakteriologi;

    Sammanfattning : The identification and classification of bacteria was initially performed with morphological methods applied on cultivated bacteria. It was not until the mid 1970s, when sequences of ribosomal RNA were discovered to be useful for bacterial evolution, that a new era started. This method showed to be far more accurate for bacterial identification. LÄS MER

    Sammanfattning : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.

  4. 3. The importance of maturation factors in 30S ribosomal subunit assembly

    Författare :Stefan Nord; Mikael Wikström; Dan Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; 30S; rRNA; RimP; RbfA; C23U; rpsE; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The assembly of the ribosome is a complex process that needs to be highly efficient to support maximum growth. Although the individual subunits of the ribosome can be reconstituted in vitro, such a reaction is inefficient in comparison to the assembly rate in vivo. LÄS MER

  5. 4. Characterization of the Intestinal Microbiota by DNA-Based Methods

    Författare :Mei Wang; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; Microbiology; Ulcerative colitis; T-RFLP; 16S rRNA; Brachyspira; Microbiota; Bacterial diversity; Bacterial translocation; Translocating bacteria;

    Sammanfattning : The intestinal flora and the bacteria found in the extraintestinal sites were studied in liver injury rats, with or without Lactobacillus plantarum 299v pre-treatment. The dominating intestinal flora and translocating bacteria were typed by RAPD and identified by 16S rDNA sequencing. LÄS MER

  7. 5. Characterisation of Food Associated Bacteria by DNA based Methods, with Special Reference to Enterobacteriaceae

    Författare :Crister Olsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; 16S rRNA; TTGE; ribotyping; Rahnella; Klebsiella; HPI; Enterobacteriaceae; food; Livsmedelsteknik;

    Sammanfattning : The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. LÄS MER
