 Project objective

Recently, a novel type of long, filamentous bacteria has been discovered, which are capable of guiding electrical currents over centimeter distances. These so-called “cable bacteria” were first isolated from marine sediments, and laboratory experiments demonstrate that electrons are passed on from cell to cell along the longitudinal axis of the filaments. This long-distance electron transport radically extends the physiological capacities of prokaryotes, and profoundly changes our understanding of biogeochemical transformations in marine sediments. In my PhD research, I have documented that in addition to oxygen, these sulphur oxidizing bacteria can also use nitrate as an electron acceptor. This new form of “electrogenic” nitrate reduction could have important implications for the removal of bio-available N in marine ecosystems. However, the effect of this newly described nitrate reducing process on the global nitrogen cycle, as well as the factors that ultimately control the occurrence, remain unknown. The goal of this project is to identify the end products of the electrogenic nitrate reduction and the environmental controls that regulate its occurrence. This project will hence provide new insights into the physiological abilities of micro-organisms and improve our understanding of N dynamics in marine sediments, strengthening European excellence in these fields of research. The goals of the project will be attained by combining state-of-the-art biogeochemical techniques with a novel and interdisciplinary approach based on principles traditionally applied in microbiology, electrochemistry and geophysics. This project will allow me to work on an up-to-front topic and thus to build up a unique research profile among the large number of researchers in the of nitrogen cycling.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "ENIRIS" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
