Open AccessDie chemische Sprache von Symbiosen sichtbar machen
Small molecules — metabolites — provide the basis for chemical interactions between hosts and microbes. Especially in animal-microbe symbioses, the close physical interactions require a spatial organization of...

Verrucomicrobia use hundreds of enzymes to digest the algal polysaccharide fucoidan
Brown algae are important players in the global carbon cycle by fixing carbon dioxide into 1 Gt of biomass annually, yet the fate of fucoidan—their major cell wall polysaccharide—remains poorly understood. Mic...

Spatial metabolomics of in situ host–microbe interactions at the micrometre scale
Spatial metabolomics describes the location and chemistry of small molecules involved in metabolic phenotypes, defence molecules and chemical interactions in natural communities. Most current techniques are un...

Open AccessTwo intracellular and cell type-specific bacterial symbionts in the placozoan Trichoplax H2
Placozoa is an enigmatic phylum of simple, microscopic, marine metazoans1,2. Although intracellular bacteria have been found in all members of this phylum, almost nothing is known about their identity, location a...

Open AccessRole of N-terminal protein formylation in central metabolic processes in Staphylococcus aureus
Bacterial protein biosynthesis usually depends on a formylated methionyl start tRNA but Staphylococcus aureus is viable in the absence of Fmt, the tRNAMet formyl transferase. fmt mutants exhibit reduced growth ra...

Open AccessFed-batch process for the psychrotolerant marine bacterium Pseudoalteromonas haloplanktis
Pseudoalteromonas haloplanktis is a cold-adapted γ-proteobacterium isolated from Antarctic sea ice. It is characterized by remarkably high growth rates at low temperatures. P. haloplanktis is one of the model org...

Chemical characterization of soil extract as growth media for the ecophysiological study of bacteria
We investigated the composition of soil-extracted solubilized organic and inorganic matter (SESOM) prepared from three different soils. Growth of various bacterial strains in these soil extracts was evaluated ...
