Open AccessDifferential regulation of degradation and immune pathways underlies adaptation of the ectosymbiotic nematode Laxus oneistus to oxic-anoxic interfaces
Eukaryotes may experience oxygen deprivation under both physiological and pathological conditions. Because oxygen shortage leads to a reduction in cellular energy production, all eukaryotes studied so far cons...

Open AccessMikrobieller Plastikabbau im Meer: die Suche nach dem Unwahrscheinlichen
Microplastic particles have been found in all the world’s oceans. Since their surfaces are microbially colonised, research is currently determining whether microbes are able to degrade the synthetic polymers. ...

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...

A marine bacterial enzymatic cascade degrades the algal polysaccharide ulvan
Marine seaweeds increasingly grow into extensive algal blooms, which are detrimental to coastal ecosystems, tourism and aquaculture. However, algal biomass is also emerging as a sustainable raw material for th...

Centrifugation-Based Enrichment of Bacterial Cell Populations for Metaproteomic Studies on Bacteria–Invertebrate Symbioses
Owing to high sample complexity, metaproteomic investigations on bacteria–animal symbioses with two or more uncultured partners can be challenging. A selective isolation or enrichment of distinct (sub-)populat...

Open AccessGenome sequence of the sulfur-oxidizing Bathymodiolus thermophilus gill endosymbiont
Bathymodiolus thermophilus, a mytilid mussel inhabiting the deep-sea hydrothermal vents of the East Pacific Rise, lives in symbiosis with chemosynthetic Gammaproteobacteria within its gil...

Open AccessNitrogen fixation in a chemoautotrophic lucinid symbiosis
The shallow water bivalve Codakia orbicularis lives in symbiotic association with a sulfur-oxidizing bacterium in its gills. The endosymbiont fixes CO2 and thus generates organic carbon compounds, which support t...

Open AccessThe anaerobic linalool metabolism in Thauera linaloolentis 47 Lol
The betaproteobacterium Thauera linaloolentis 47LolT was isolated on the tertiary monoterpene alcohol (R,S)-linalool as sole carbon and energy source under denitrifying conditions. Growth experiments indicated th...

Open AccessLinalool isomerase, a membrane-anchored enzyme in the anaerobic monoterpene degradation in Thauera linaloolentis 47Lol
Thauera linaloolentis 47Lol uses the tertiary monoterpene alcohol (R,S)-linalool as sole carbon and energy source under denitrifying conditions. The conversion of linalool to geraniol ...

Open AccessThe oxygen-independent metabolism of cyclic monoterpenes in Castellaniella defragrans 65Phen
The facultatively anaerobic betaproteobacterium Castellaniella defragrans 65Phen utilizes acyclic, monocyclic and bicyclic monoterpenes as sole carbon source under oxic as well as anoxic conditions. A biotransfor...
