ProteomicsBiopearling: Chains of interconnected outer membrane vesicles in a marine flavobacterium
Large surface-to-volume ratios provide optimal nutrient uptake conditions for small microorganisms in oligotrophic habitats. The surface area can be increased with appendages. Here we describe chains of interconnecting vesicles protruding from cells of the flavobacterial strain Hel3_A1_48 originatin...

ProteomicsProteogenomic characterization of microbial communities fueled by metal-sulfide oxidation of inactive hydrothermal chimneys
Iron-sulfur minerals such as pyrite are found in many marine benthic habitats. At deep-sea hydrothermal vent sites they occur as massive sulfide chimneys. Hydrothermal chimneys formed by mineral precipitation from reduced vent fluids upon mixing with cold oxygenated sea water. While microorganisms i...

ProteomicsEffects of hypoxia-reoxygenation stress on mitochondrial proteome and bioenergetics of the hypoxia-tolerant marine bivalve Crassostrea gigas
Intermittent hypoxia is a common stressor in estuarine and coastal habitats due to the diurnal and tidal cycles of oxygen availability. Oxygen deficiency results in energy stress by limiting aerobic ATP production, while reoxygenation may lead to oxidative injury due to the excessive production of r...

ProteomicsMetaproteome analysis of hydrothermal vent chimney biofilms
At hydrothermal vent sites, chimneys consisting of sulfides, sulfates, and oxides are formed upon contact of reduced hydrothermal fluids with oxygenated seawater. The walls and surfaces of these chimneys are an important habitat for vent-associated microorganisms. We used community proteogenomics to...

ProteomicsMethanosaeta and Candidatus Velamenicoccus archaeovorus
The Candidatus phylum Omnitrophica (candidate division OP3) occurs ubiquitous in anaerobic habitats, but is currently characterized only by draft genomes from metagenomes and single cells. We had visualized cells of the phylotype OP3 LiM in methanogenic cultures on limonene as small epibiontic cells...

ProteomicsCharacterization of a thaumarchaeal symbiont that drives incomplete nitrification in the tropical sponge Ianthella basta
Marine sponges represent one of the few eukaryotic groups that ubiquitously harbor symbiotic members of the Thaumarchaeota, which are important chemoautotrophic ammonia-oxidizers in many environments. However in most studies, direct demonstration of ammonia-oxidation by these archaea within sponges ...

To characterize the taxonomic and functional diversity of biofilms on plastics in marine environments, plastic pellets (PE and PS, ø 3mm) and wooden pellets (as organic control) were incubated at three stations: at the Baltic Sea coast in Heiligendamm (coast), in a dead branch of the river Warnow in...

Humans harbor numerous species of colonic bacteria that digest the fiber polysaccharides in commonly consumed terrestrial plants. More recently in history, regional populations have consumed edible seaweeds (macroalgae) containing unique polysaccharides. However, it remains unclear how extensively g...

ProteomicsGrazing-resistance, antibiotic production and internal carbon cycling are characteristics for bacteria that prevail in long-term enclosure experiments
Enclosure experiments are frequently used to investigate the impact of changing environmental conditions on microbial assemblages. Yet, the question how individual members of bacterial communities respond to challenges posed by the incubation itself remained unanswered. We used metaproteomic profili...

Bathymodiolus mussels inhabiting deep-sea hydrothermal vents harbor bacterial symbionts in their gills, which support the animals’ diet. While the basic mechanisms of energy generation and CO2 fixation that drive these symbioses are largely established, details of molecular interactions between the ...
