Biological vs. chemical regulation of nitrite concentrations in acidic and neutral pH soils : a study of kinetics and bacterial denitrifier communities
(Master thesis, 2015-11-06)Denitrification is an anaerobic microbial respiratory process, which takes part in the global biogeochem- ical nitrogen cycle. Microbial denitrifiers contribute to the global recirculation of nitrogen, by stepwise reduction ... -
Characterization of Streptococcus pneumoniae lacking the gene dacA, which encodes Penicillin Binding Protein 3 (PBP3)
(Master thesis, 2012-10-19) -
Cloning, expression, purification and characterization of a sulfate transporter from Legionella pneumophila
(Master thesis, 2013-09-09)Legionella pneumophila is a gram-negative, non-encapsulated, rod-shaped facultative intracellular pathogen with a single, polar flagellum. The SO42- transporter protein (LPL0734) is a membrane protein of Legionella ... -
Co-aggregation among Rhodococcus and Acinetobacter from the food industry
(Master thesis, 2013-10-28)Microorganisms’ attachment to surfaces and consequently biofilm formation creates problems in food production industries. Such problems include contamination of equipment and products. Biofilm development is the result of ... -
Diversity in germination response among Bacillus licheniformis strains
(Master thesis, 2012-09-12)Flere studier har blitt utført for å beskrive germineringsegenskaper i forskjellige Bacillus licheniformis-stammer. Stammene har påviste forskjeller i operonet som koder for germineringsreseptoren GerA, som er forbundet ... -
Evaluation of Liquid Array Diagnostics for microbiota-based diagnosis of dysbiosis
(Master thesis, 2018)The human gut contains a complex community of microorganisms that impact our health and general well-being. Based on observed microbial patterns, a balanced composition can be defined, known as normobiosis. Deviations from ... -
Genome-wide transcriptional profiling of Clostridium species during sporulation
(Master thesis, 2016-11-22)Dormancy strategies utilized by bacteria contribute to their survival under adverse conditions, as well as persistence and transmission between hosts. The formation of endospores produces some of the most resilient forms ... -
Gut microbiota and tumorigenesis in A/J min mice
(Master thesis, 2016-08-10)Colorectal cancer is one of the most common cancer type worldwide. Mouse models are important tools in cancer research and the recently developed A/J Min+ mouse model has shown to develop a great amount of lesions in colon, ... -
Hemming og frigjøring av biofilm hos bakterier isolert fra næringsmiddelindustrien
(Master thesis, 2013-09-06)Flere bakterieslekter har evne til å danne biofilm og det er antatt at biofilmdannelse spiller en rolle når det kommer til deres overlevelse i næringsmiddelindustrien. Enda viktigere er kanskje det at deres tilstedeværelse ... -
In silico and in vitro studies of a non-commensal soil bacterium and its interactions with a mammalian host
(Master thesis, 2013-07-08)Methylococcus capsulatus (Bath) er en Gram-negativ, metanotrof bakterie. Til tross for at den aldri har vært beskrevet å være en del av tarmflora har M. capsulatus (Bath) vist seg å ha positive effekter ved inflammatoriske ... -
