Bioreactor Sandpit Workshop 2013: Designing and Building Pressure Tools for Worldwide Biological Investigations

Date: Monday, 26 August 2013 - Thursday, 29 August 2013

Location: Veyrier-du-Lac, France

The Deep Carbon Observatory will hold a sandpit style workshop for 20-30 participants from industrial and academic affiliations on 26-29 August 2013 at Les Pensières Conference Centre on the shores of Lake Annecy in France.  Financial support will be available to design, build and test the prototype(s) that meet the requirements agreed upon by the community. Conference center room and board will be supplied. Partial transportation support is also available. Bioreactor users, representatives of pressure apparatus companies and academic high-pressure technical networks, as well as scientists and engineers involved in international drilling programs are encouraged to attend the workshop.

Multiple bioreactor designs currently exist but they are not necessarily compatible and limit international coordination and collaboration among deep life scientists. These pressure chambers are critical for collecting during field expeditions, transporting, and investigating microbial cultures and microbial activities at extreme conditions in the laboratory. High-pressure vessels have been developed that are suitable for collecting deep-sea or deep-continental samples under pressure for in situ analysis, but it is not yet possible to sustain samples at appropriate high pressure throughout the whole sequence of analyses. Materials, pressure fittings, and other key design parameters are not uniform. The technical constraints encountered during deep drilling will also be considered. An open discussion and debate among experts and industry representatives is necessary to identify the best possible design specifications.

The primary workshop objective is to identify the optimum design for a new generation of a suite of interconnectable high-pressure/temperature bioreactors that can transport pressurized samples overseas from one laboratory to another. Reaching this objective involves establishing design priorities, producing a prototype design, and constructing and testing that prototype.

Application deadline 15 June 2013.
