In vivo polydopamine coating of Rhodobacter sphaeroides for enhanced electron transfer

Ardemis Anoush Boghossian, Melania Reggente

Recent advances in coupling light-harvesting microorganisms with electronic components have led to a new generation of biohybrid devices based on microbial photocatalysts. These devices are limited by the poorly conductive interface between phototrophs and ...

Microbes support enhanced nitrogen requirements of coral holobionts in a high CO 2 environment

Nils Rädecker, Gabriela Hannah Holligan Perna

Ocean acidification is posing a threat to calcifying organisms due to the increased energy requirements of calcification under high CO2 conditions. The ability of scleractinian corals to cope with future ocean conditions will thus depend on their ability t ...

Community-Level Responses to Iron Availability in Open Ocean Plankton Ecosystems

Anna Carratala Ripolles

Predicting responses of plankton to variations in essential nutrients is hampered by limited in situ measurements, a poor understanding of community composition, and the lack of reference gene catalogs for key taxa. Iron is a key driver of plankton dynamic ...

Assimilation, translocation, and utilization of carbon between photosynthetic symbiotic dinoflagellates and their planktic foraminifera host

Anders Meibom, Emmanuelle Geslin, Charlotte Madeleine Nicole Lekieffre

Some species of planktic foraminifera inhabiting oligotrophic surface water environments are in an obligate symbiotic relationship with dinoflagellate microalgae, which can assimilate carbon (C) through photosynthesis. However, the mechanism and dynamics o ...

Subcellular Investigation of Photosynthesis-Driven Carbon and Nitrogen Assimilation and utilization in the Symbiotic Reef Coral: Pocillopora damicornis

Anders Meibom, Stéphane Laurent Escrig, Isabelle Domart-Coulon, Christophe Kopp

UNLABELLED: Reef-building corals form essential, mutualistic endosymbiotic associations with photosynthetic Symbiodinium dinoflagellates, providing their animal host partner with photosynthetically derived nutrients that allow the coral to thrive in oligot ...

Sensing the dynamics of oxidative stress using enhanced absorption in protein-loaded random media

Olivier Martin, Christian Santschi, Vera Slaveykova-Startcheva, Guillaume Suarez

Reactive oxygen species play a key role in cell signalling and oxidative stress mechanisms, therefore, sensing their production by living organisms is of fundamental interest. Here we describe a novel biosensing method for extracellular detection of endoge ...

Highly Diverse and Seasonally Dynamic Protist Community in a Pristine Peat Bog

Enrique Lara

Culture-independent molecular methods based on the amplification, cloning and sequencing of small-subunit ribosomal RNA genes (SSU rDNAs) are powerful tools to study the diversity of microorganisms. Despite so, the eukaryotic microbial diversity of many ec ...

Cyanobacterial Natural Products for the Inhibition of Biofilm Formation and Biofouling

Karl Gademann

Biofouling is defined by the non-specific attachment of biological material (proteins, carbohydrates, prokaryotic cells and higher organisms) to surfaces upon their exposure to any biological fluid. Biofouling is a serious problem in many areas ranging fro ...

Genetic diversity of cyanobacterial communities in Lake Kinneret (Israel) using 16S rRNA gene, psbA and ntcA sequence analyses

The genetic diversity of cyanobacterial communities was studied at various depths in Lake Kinneret (Israel). Denaturing gradient gel electrophoresis (DGGE) of specific 16S rRNA gene PCR products showed significant differences in the cyanobacterial communit ...

Molecular analysis of the biodiversity of protists in hydrocarbon-polluted and pristine soils

Enrique Lara

Eukaryotic microorganisms are an essential component of the Earth's global diversity. It is believed that the number of protistan taxa far outnumbers the one of viruses and bacteria. The taxonomic classification of these organisms, which also represent the ...
