Hydroxypyridinones in nitrogen-fixing bacterial cultures: a metal buffer for molybdenum and simulation of natural conditions

Autor: Jan Frieder Mohr, Sofia Gama, Sébastien Roy, Jean-Philippe Bellenger, Winfried Plass, Thomas Wichard

Publikováno v: Metallomics : integrated biometal science. 14(8)

Organic matter regulates the availability of important trace elements in aquatic and terrestrial ecosystems by acting as a source and container for microbes. To overcome the limitation of trace elements, nitrogen-fixing bacteria, e.g. release low-mol

Macroalgal microbiomes have core functions related to biofilm formation, growth, and morphogenesis of seaweeds. In particular, the growth and development of the sea lettuce Ulva spp. (Chlorophyta) depend on bacteria releasing morphogenetic compounds.

Analysis of algal growth- and morphogenesis- promoting factors in an integrated multi-trophic aquaculture system for farming Ulva spp

Autor: Jan Frieder Mohr, Maria H. Abreu, Thomas Wichard, Gianmaria Califano, Fatemeh Ghaderiardakani, Juliet C. Coates

Publikováno v: Aquaculture Environment Interactions, Vol 11, Pp 375-391 (2019)

The marine green macroalgal genus Ulva (Chlorophyta) requires the presence of a combination of regulatory morphogenetic compounds released by their associated epiphytic bacteria in addition to nutritional parameters. The activity of algal growth- and

Frankobactin Metallophores Produced by Nitrogen-Fixing

Autor: Jan Frieder, Mohr, Florian, Baldeweg, Michael, Deicke, Cristina F, Morales-Reyes, Dirk, Hoffmeister, Thomas, Wichard

Publikováno v: Journal of natural products. 84(4)

A series of new metallophores, referred to as frankobactins, were extracted from cultures of the symbiotic and nitrogen-fixing actinobacterium

Metallophore profiling of nitrogen-fixing Frankia spp. to understand metal management in the rhizosphere of actinorhizal plants

Autor: Michael Deicke, Peter Herzsprung, Jean-Philippe Bellenger, Thomas Wichard, Sébastien Roy, Jan Frieder Mohr

Publikováno v: Metallomics : integrated biometal science. 11(4)

Frankia spp. are widespread nitrogen-fixing soil bacteria, which often live in symbiosis with a broad range of hosts. Metal homeostasis plays a crucial role in the success of the symbiosis regarding the acquisition of essential trace metals and detox

Iron-organic matter complexes accelerate microbial iron cycling in an iron-rich fen

Autor: Jan Frieder Mohr, Kirsten Küsel, Stefan Kügler, Carl-Eric Wegner, Rebecca E. Cooper, Thomas Wichard

Publikováno v: The Science of the total environment. 646

The accessibility of iron (Fe) species for microbial processes is dependent on solubility and redox state, which are influenced by complexation with dissolved organic matter (DOM) and water-extractable organic matter (WEOM). We evaluated the complexa

Gramibactin is a bacterial siderophore with a diazeniumdiolate ligand system

Autor: Winfried Plass, Sofia Gama, Bianca Hoffmann, Jan Frieder Mohr, Thomas Wichard, Ron Hermenau, Hanspeter Saluz, Christian Hertweck, Keishi Ishida, Michel Pfeifer-Leeg

Publikováno v: Nature chemical biology. 14(9)

Genome mining and chemical analyses revealed that rhizosphere bacteria (Paraburkholderia graminis) produce a new type of siderophore, gramibactin, a lipodepsipeptide that efficiently binds iron with a logβ value of 27.6. Complexation-induced proton

Metallophore mapping in complex matrices by metal isotope coded profiling of organic ligands

Autor: Jan Frieder Mohr, Jean-Philippe Bellenger, Michael Deicke, Thomas Wichard

Publikováno v: The Analyst. 139:6096-6099

Metal isotope coded profiling (MICP) introduces a universal discovery platform for metal chelating natural products that act as metallophores, ion buffers or sequestering agents. The detection of cation and oxoanion complexing ligands is facilitated
