Microcystin (MC) is a common and widespread toxin which represents a health hazard to humans and animals. MC toxin concentrations are monitored by various direct or proxy techniques (HPLC, LC-MS/MS, ELISA, PPIA), however, these techniques do not disc

Autor: Virginie Riou, Marine Périot, Isabelle C. Biegala

Publikováno v: Frontiers in Microbiology, Vol 8 (2017)

Oligonucleotide probes are increasingly being used to characterize natural microbial assemblages by Tyramide Signal Amplification-Fluorescent in situ Hybridization (TSA-FISH, or CAtalysed Reporter Deposition CARD-FISH). In view of the fast-growing rR

The Mediterranean Sea is one of the most oligotrophic marine areas on earth where nitrogen fixation has formally believed to play an important role in carbon and nitrogen fluxes. Although this view is under debate, the diazotrophs responsible for thi

The hydrothermal-vent tubeworm Riftia pachyptila relies entirely on its intracellular chemoauto- trophic symbionts to sustain its metabolism. The host must therefore provide them with inorganic metabolites, including carbon. This study describes a to
