Ecophysiological Investigation of Cyanobacteria using Controlled Cultivation


EMSL Project ID
16702

Abstract

This project targets the development and operation of a fully instrumented photobioreactor that will serve to cultivate Cyanobacteria under well defined and controlled conditions. This capability not only will provide a more complete understanding of the physiological response of cells to changes in environmental conditions, it will provide high quality, reproducible samples that will optimize biological information obtained from advanced analytical technologies. This project will also investigate the production, composition, and conductivity of extracellular nanowires produced by Synechocystis and, perhaps, Cyanothece in response to CO2 limitation. In the past week we have determined that Synechocystis does indeed produce conductive nanowires. We will now expand upon this scientifically significant discovery to more completely describe their role in physiology and metabolism of cyanobacterial communities.
