Microbial Communities in the Terrestrial Subsurface
(2025-01-23)Terrestrial subsurface habitats represent a significant portion of Earth's prokaryotic biomass. However, our understanding of microbial diversity and functions in these environments, particularly in arid regions, remains ... -
Social relationships: key to gut microbiome composition in wild redfronted lemurs?
(2022-03-03)The gut microbiome consists of the prokaryotic and eukaryotic communities inhabiting the gastrointestinal tract of an animal and plays a pivotal role in the health of the host. This microbial community is highly dynamic ... -
Structure and function of microbial communities involved in biomineralization
(2022-01-27)Different aspects of carbonate precipitation are considered in this study. The first part examines carbonates in a model system that helps to explain the initial steps in the formation of so-called concretions, which are ... -
Organic-rich shales as archive and resource for microbial extremophiles
(2021-09-10)Organic-rich shales of sedimentary basins are the most abundant carbon-rich rocks throughout the world, formed as a consequence of different geological events. The repetitive sedimentation of the mudstones, clay particles, ... -
The velvet protein Vel1 controls initial plant root colonization and conidia formation for xylem distribution in Verticillium wilt
(2021-08-24)The velvet family of regulatory proteins is well-conserved in fungi and links developmental processes and secondary metabolite production. These proteins comprise a velvet domain for DNA binding and dimerization with ... -
The potential of plant growth-promoting bacteria to enhance rhizoremediation of diesel fuel-contaminated sites
(2021-06-07)Crude oil and fuel spillages are the most persistent environmental menace resulting from oil and gas exploration, production and utilisation. The United States Environmental Protection Agency (US EPA) estimated that ... -
Metagenomic approaches to discover lipolytic enzymes
(2021-05-04)Lipolytic enzymes, including lipases and esterases, have a wide spectrum of applications in various industrial fields, due to their functional versatility. Despite an increasing number of lipolytic enzymes that have been ... -
Antagonistic fluorescent pseudomonads cause evasion of the plant pathogen Verticillium by controlling hyphal growth and polarity
(2021-04-09)Abstract Soil borne phytopathogenic Verticillia constitute increasing yield losses. Due to a lack of resistant cultivars as well as appropriate fungicides, the usage of biocontrol agents like fluorescent pseudomonads might ... -
Impact of rainforest conversion: How prokaryotic communities respond to anthropogenic land use changes
(2020-12-03)In this thesis, the impact of rainforest conversion to the managed land use systems jungle rubber, rubber plantation and oil palm plantation on structure and function of soil microbial communities was investigated. The ... -
Distribution and ecological characteristics of members of the Roseobacter group
(2020-08-27)Marine Rhodobacteraceae are collectively referred to as the Roseobacter group, and due to their functional versatility and high abundance in diverse marine habitats, serve as model organisms in the study of microbial ... -
Assessment of antibiotic resistance in soil and its link to different land use types and intensities
(2020-07-15)Nowadays, bacterial infections pose a serious risk for human health again, due to multi-resistant pathogens insensitive to antibiotic treatment. Some of the antibiotic resistance genes (ARGs) carried by these pathogens ... -
Health consequences of group living in wild Verreaux’s sifakas (Propithecus verreauxi)
(2020-07-10)The evolution of sociality exposed individuals to several new health-related costs and benefits, which fundamentally affect their survival and reproductive success. Group living provides better access to food and mates and ... -
Compositional and functional shifts in belowground fungal communities in tropical land-use systems
(2020-06-23)Tropical low-land rainforests are one of the most diverse ecosystems in the world and provide valuable ecosystem services such as climate change mitigation. They are immensely threatened by expanding human land-use. ... -
Metagenomics in One Health — from standardization to targeted application
(2020-04-21)This thesis is meant to further the applicability of metagenomics in One Health by discussing key forms of standardization, as well as targeted applications. Metagenomics is a powerful pathogen-agnostic tool, allowing for ... -
Effects of cropping systems on plant-associated microbial communities of faba bean and wheat
(2019-07-24)Beneficial plant-associated microorganisms are widely acknowledged as key promoter in plant growth and health. Although playing crucial roles in ecosystem functioning and in a sustainable agriculture, our knowledge on the ... -
Discovery and Functional Characterization of Novel Soil-metagenome Derived Phosphatases
(2019-07-22)Phosphatases, including phytases, play a major role in phosphorous cycle, cell metabolism, biotechnology, and pathogenic processes. Despite their relevance as biocatalysts, the study of phosphatases/phytases has been almost ... -
Taxonomic and Functional Characterization of Biopolymer-degrading Microbial Communities in the Intestinal Tract of Beavers
(2019-05-09)The mammalian gut harbors a complex and specialized microbiota, which includes all tree domains of life (Archaea, Bacteria, and Eukarya). Bacteria are the most abundant group within the gut system, and they take part in ... -
Phylogenetic and functional diversity of soil prokaryotic communities in temperate deciduous forests with different tree species
(2019-04-30)Forest ecosystems provide an important contribution to global carbon storage through processes mediated by trees. As the dominant forest vegetation, trees largely drive primary productivity and mediate the flow of aboveground ... -
Symbiotic adaptation of prokaryotic microorganisms in extreme deep-sea environments
(2019-04-10)Extreme deep-sea environments are widespread and intensively studied in the last decades. They are of special interest since living organisms in those habitats happen to live at the expenses of the fluids emitted from the ... -
Diversity and function of root-associated fungal communities in relation to nitrogen nutrition in temperate forests
(2019-01-29)Ectomycorrhizal fungi form symbiotic association with roots of a variety of plant species. They provide plants with nutrients in exchange of photosynthetic carbohydrates. In natural ecosystems, plants form associations not ...
