Assessment of the toxicity of inorganic and organic pollutants using the benthic alga Closterium ehrenbergii
(2024-03-20)In this thesis, Closterium ehrenbergii was selected as test species for the assessment of the toxicity of environmentally relevant pollutants towards a representative of benthic algae. Therefore, a miniaturized bioassay ... -
Untersuchung zur Sekretion und Abtrennung von Lipiden aus Mikroalgen
(2022-02-24)Due to the high costs of downstream processing, the production of low-value substances from microalgae is currently not economically feasible. On opportunity to reduce the downstream costs is the process of in situ-extraction ... -
Vegetation and functional diversity of sand dune habitats between and within different bioclimatic regions
(2017-08-08)Use of plant functional types has a long tradition in ecology from the time that von Humboldt offered the first physiognomic classification of plants based on growth form. In recent years, the application of functional ... -
Biodiversity of terrestrial algal communities from soil and air-exposed substrates using a molecular approach
(2016-03-08)Terrestrial green microalgae are important primary producers in various habitats like soils, stone (epilithic and endolithic), tree bark and artificial hard substrates. In this thesis, the molecular diversity of green algae ... -
Green algae in soil: assessing their biodiversity and biogeography with molecular-phylogenetic methods based on cultures
(2016-02-04)Green microalgae (Chlorophyta) dominate soils in the northern temperate climate zone, however, their biodiversity is still poorly understood. Available diversity inventories rely on light microscopy and morphospecies, which ... -
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) ... -
Tracking HIV-1 genetic variation: recombination and N-linked glycosylation sites
(2007-11-02)The last 26 years saw a rampant global epidemic of HIV-1. HIV-1 s extraordinary diversity is seeded by a high mutation rate, rapid replication, frequent recombination, and strategic ... -
Functional analysis of the GlnK1 protein of Methanosarcina mazei strain Gö1: Aspects of nitrogen regulation
(2005-09-26)PII-proteins like GlnB and GlnK are ubiquitous distributed small regulator proteins that play a key role in regulation of nitrogen metabolism by sensing and signalling the intracellular ...
