Characterization of airborne bacteria at an underground subway station
Dybwad, Marius; Granum, Per Einar; Bruheim, Per; Blatny, Janet Martha (2012)The reliable detection of airborne biological threat agents depends on several factors, including the performance criteria of the detector and its operational environment. One step in improving the detector's performance ... -
Genetic characterization of trh positive Vibrio spp. isolated from Norway
Ellingsen, Anette Bauer; Olsen, Jaran Strand; Granum, Per Einar; Rørvik, Liv Marit; Gonzalez-Escalona, Narjol (2013)The thermostable direct hemolysin (TDH) and/or TDH-related hemolysin (TRH) genes are carried by most virulent Vibrio parahaemolyticus serovars. In Norway, trh+ V. parahaemolyticus constitute 4.4 and 4.5% of the total number ... -
Genetic distribution of 295 Bacillus cereus group members based on adk-screening in combination with MLST (Multilocus Sequence Typing) used for validating a primer targeting a chromosomal locus in B. anthracis
Olsen, Jaran S.; Skogan, Gunnar; Fykse, Else Marie; Rawlinson, Elizabeth L. A.; Tomaso, Herbert; Granum, Per Einar; Blatny, Janet (2007)The genetic distribution of 295 Bacillus cereus group members has been investigated by using a modified Multilocus Sequence Typing method (MLST). By comparing the nucleic acid sequence of the adk gene fragment, isolates ... -
Genotyping of B. licheniformis based on a novel multi-locus sequence typing (MLST) scheme
Madslien, Elisabeth; Olsen, Jaran Strand; Granum, Per Einar; Blatny, Janet Martha (2012)Background Bacillus licheniformis has for many years been used in the industrial production of enzymes, antibiotics and detergents. However, as a producer of dormant heat-resistant endospores B. licheniformis might ... -
Identification and quantification of lichenysin – a possible source of food poisoning
Rønning, Helene Thorsen; Madslien, Elisabeth Henie; Asp, Tone Normann; Granum, Per Einar (2015)Lichenysin produced by 53 different Bacillus licheniformis strains has been structurally examined with a qualitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) method using quadrupole-time-of-flight mass ... -
L-alanine-induced germination in Bacillus licheniformis -the impact of native gerA sequences
Madslien, Elisabeth Henie; Granum, Per Einar; Blatny, Janet Martha; Lindback, Toril (2014)Background L-alanine, acting through the GerA receptor, was recently found to be an efficient germinant in Bacillus licheniformis ATCC14580/DSM13. Results In this study, we show that several of 46 examined B. ... -
Role of the gerA operon in L-alanine germination of Bacillus licheniformis spores
Løvdal, Irene Stranden; From, Cecilie; Madslien, Elisabeth; Romundset, Kristin Cecilia Saue; Klufterud, Elin; Rosnes, Jan Thomas; Granum, Per Einar (2012)Background The genome of Bacillus licheniformis DSM 13 harbours three neighbouring open reading frames showing protein sequence similarities to the proteins encoded from the Bacillus subtilis subsp. subtilis 168 gerA ...
