Verticillium dahliae transcription factors Som1 and Vta3 control microsclerotia formation and sequential steps of plant root penetration and colonisation to induce disease
(2018-10-12)Verticillium dahliae belongs to the soil-borne ascomycete fungi. It causes wilt diseases and early senescence in more than 200 plant species including economically important crops. It can exist in the soil without a host ... -
Impact of Rain Forest Transformation on Roots and Functional Diversity of Root-Associated Fungal Communities
(2017-12-07)Tropical rain forests are representing biodiversity hotspots, but their species richness is threatened by human driven land use changes. Between 1990 and 2015 most of the global deforestation of about 129 million hectares ... -
Analyse und Charakterisierung regulatorischer Vorgänge in Bacillus licheniformis
(2015-05-08)Analysis of RNA-Seq data in a genome context sensitive approach to identify known and novel RNA-regulatory elements and events applied by Bacillus licheniformis DSM13 to adapt its physiology to a productive fermentation. ... -
Natural products from Myxococcales and Bacillales & Description of a new myxobacterial taxon
(2015-02-19)With the advent of new pathogens and upsurge in the number of antibiotic resistant microbes, concerted efforts need to be made by pharmaceutical, biotechnological and academic communities to pace up the antibiotic discovery ... -
GlmY and GlmZ: a hierarchically acting cascade composed of two small RNAs
(2014-09-10)In Escherichia coli and other enterobacteria, the homologous small RNAs (sRNAs) GlmY and GlmZ act in a hierarchical manner to feedback control expression of key enzyme glucosamine-6-phosphate (GlcN6P) synthase GlmS. Enzyme ... -
Zelltyp-spezifische Interaktionen von Toxoplasma gondii und murinen Skelettmuskelzellen in vitro
(2014-06-26)Toxoplasma gondii is one of the most common intracellular protozoan parasites worldwide and an important human pathogen. Its life cycle includes three stages: sporozoites, tachyzoites and bradyzoites. While sporozoites are ... -
Untersuchung zur kohlenstoffabhängigen Wasserstoffperoxidproduktion und Virulenz in Mycoplasma pneumoniae und Mycoplasma genitalium
(2013-05-15)The human pathogens M. genitalium and M. pneumoniae use hydrogen peroxide as an important virulence factor. It could be shown that the glycerol-3-phosphate dehydrogenase (GlpD) is the key enzyme for the production of this ... -
Identification and Characterization of Microbial Key Functions in Soils of the German Biodiversity Exploratories Representing Different Land Use and Management Types
(2012-05-11)Soil probably harbors the highest microbial species diversity of any environment on Earth and represents a major reservoir of microbial taxonomic, genomic, and metabolic diversity. The most promising approach to gain ... -
Investigation of storage polysaccharide metabolism in lactic acid bacteria
(2011-10-21)Glycogen biosynthesis and its regulation have been investigated extensively in bacteria at the level of ADP-Glc synthesis. The enzyme ADP-glucose pyrophosphorylase (ATP: α-dglucose-1-phosphate ... -
Oxylipinstoffwechsel in Physcomitrella patens
(2011-07-01)During the presented doctoral thesis enzymes of the oxylipin metabolism from P. patens have been purified & described. Therefore, the bifunctional PpLOX1 & two AOC enzymes (PpAOC1 & PpAOC2) ... -
Physiologische Untersuchungen zur Regulation des Aminosäure-Stoffwechsels von Bacillus licheniformis DSM13
(2011-05-05)In contrast to his close relatives Bacillus licheniformis is able to grow fermentative under strict anaerobic conditions. Investigations of the anaerobic growth in a defined medium have ... -
Assessment of the functional diversity of soil microbial communities in the German Biodiversity Exploratories by metagenomics
(2011-04-18)Soil is the most complex microbial habitat on Earth with respect to bacterial species diversity and community size. Therefore, assessing the bacterial community composition in soil is a ... -
Die Rolle der beiden Transkriptionsfaktoren AtbZIP1 und AtbZIP53 aus Arabidopsis thaliana in der Anpassung des pflanzlichen Metabolismus an Energiemangelbedingungen
(2011-02-11)Energy deprivation, induced for example by long periods of darkness, leads to dramatic reprogramming of the plant's metabolism. Macromolecules like proteins, amino acids, fatty acids, ... -
Stammdesign in B. licheniformis
(2010-07-29)Bacillus licheniformis is an organism of great scientific and industrial interest. The analysis of this important bacterium suffers from poor genetic accessibility. Therefore DNA transfer ... -
Metagenomanalysen von zwei Habitaten mit (hemi-)cellulolytischen mikrobiellen Gemeinschaften
(2010-06-04)The analysis of metagenomes not only can give an insight into the microbial diversity of a habitat, it can also reveal new biocatalysts by screening of metagenomic DNA-libraries. In the ... -
Untersuchung der Expression und Aktivität des Molybdän-Eisen Protein in Wolinella succinogenes
(2010-04-27)In nature, the ability to fix nitrogen is restricted to some prokaryotes that possess the enzyme nitrogenase. It was possible to simulate this important process and achieve industrial ... -
Auswirkungen der Deletion membranständiger Dehydrogenasen auf Gluconobacter oxydans DSM 7145
(2009-11-06)Gluconobacter oxydans is one of the most important organisms in industrial biotechnology because of its ability to incompletely oxidize various sugars, sugar alcohols and sugar acids. The ... -
Metagenomic Analyses of Glacier Ice
(2009-06-15)The largest part of the Earth s microbial biomass is stored in cold environments, which represent almost untapped reservoirs of novel species, processes, and genes. In this study, the ... -
