Molekularbiologische Charakterisierung und vergleichende Genomik von ausgewählten Vertretern mariner Roseobacter-Stämme
(2014-03-13)The genome analyses presented in this thesis extend the current knowledge of the genomic potential of the Roseobacter clade and identify potential adaptations to ecological niches within marine habitats. New features were ... -
Molekulare Analyse des Biotin-regulatorischen Netzwerks Sinorhizobium meliloti durch Proteomanalyse, Expressionsstudien und Mutagenesen
(2003-10-16)Sinorhizobium meliloti is not able to synthesize endogenous biotin. Biotin-limitation leads to a clear reduction of metabolic activities, whereas biotin-sufficiency has a positive ... -
Molekulare, biochemische und strukturelle Untersuchungen an amylolytischen Enzymen von Thermotoga maritima MSB8
(2001-08-01)One of the most thermophilic and ancient bacteria known to date, the hyperthermophilic Thermotoga maritima MSB8 (growth range: 55°C - 90°C), degrades and fermentatively utilizes organic ... -
Produktion von monoklonalen Antikörpern und Phagenantikörpern gegen das Rinder-Prionprotein durch SFV Partikel-vermittelte Immunisierung von PrP0/0-Mäusen
(2002-01-16)The aim of my graduation work was the production and characterisation of monoclonal antibodies (mAK) and phage antibodies against the bovine Prionprotein (PrP). In the first part of the ... -
Regulation of nitrogen fixation in <i>Klebsiella pneumoniae</i>: The role of Fnr in oxygen signal-transduction
(2003-04-30)In Klebsiella pneumoniae transcriptional activity of NifA is modulated by NifL in response to combined nitrogen or molecular oxygen. NifL a flavoprotein, which is redox-sensitive, apparently ... -
Regulation of nitrogen fixation in Klebsiella pneumoniae: NifL, one protein transducing two environmental signals to the nif-transcriptional activator NifA
(2002-01-15)Klebsiella pneumoniae, NifL modulates the activity of the transcriptional activator NifA in response to combined nitrogen or external molecular oxygen. We recently showed that K. pneumoniae ... -
RNA-Seq and proteomics based analysis of regulatory RNA features and gene expression in Bacillus licheniformis
(2014-04-17)Bacillus licheniformis has been employed as industrial workhorse since several decades, especially for the production of alkaline serine proteases like Subtilisin Carlsberg, which is used as additive inhousehold detergents. ... -
Transcriptional Regulation and Differentiation in Saccharomyces and Aspergillus: jlbA, RPS26, and ARO3/4
(2003-12-19)Increasing data from genomics research revealed that the number of isogenes present within a given organism is significantly higher than anticipated a decade ago. Here we have characterised representatives of isogenes, ... -
Transformation und Pilusbiogenese: zwei voneinander unabhängige Systeme in Acinetobacter sp. BD413
(2003-10-27)The Gram negative soil bacterium Acinetobacter sp. BD413 is known for its high competence of natural transformation and its movement on solid surfaces. Genetic and biochemical studies ... -
Umwelt-Genomik als Quelle für die Isolierung von neuen Operons und Genclustern aus mikrobiellen Konsortien
(2002-10-15)The main goal of the present work was the isolation of biotin biosynthesis genes and operons from microbial consortia employing a combined enrichment and direct cloning strategy. Cosmid ... -
Untersuchung der Stressantwort von <i>Picrophilus torridus</i> mittels 2D-Gelelektrophorese und Charakterisierung ausgewählter Dehydrogenase
(2008-07-09)The thermoacidophilic archaeon Picrophilus torridus belongs to the Thermoplasmatales and is the most acidophilic microbe yet known. Optimal living conditions are at 60°C and pH 0.7. Some ... -
Untersuchungen zur Inaktivierung und Reaktivierung der Coenzym B12-abhaengigen Glycerin-Dehydratasen aus Citrobacter freundii und Clostridium pasteurianum
(2002-01-11)The coenzyme B12-dependent glycerol dehydratase of Citrobacter freundii is subject to suicide inactivation by the natural substrate glycerol during catalysis. We identified dhaF and dhaG ... -
Untersuchungen zur Physiologie des Essigsäurebakteriums Gluconobacter oxydans 621H
(2006-08-22)Gluconobacter oxydans 621H is a Gram-negative alpha-proteobacterium that belongs to the family Acetobacteriaceae. This strictly aerobic organism is adapted to growth in substrate-rich ... -
Vergleichende biochemische und strukturelle Untersuchung thermophiler α-Amylasen
(2006-02-14)A number of microorganisms exist in extreme environments. For example hot habitats are colonized by thermophilic archea and bacteria. Due to their physicochemical characteristics enzymes ...
