Absence of KpsM (Slr0977) Impairs the Secretion of Extracellular Polymeric Substances (EPS) and Impacts Carbon Fluxes in <i>Synechocystis</i> sp. PCC 6803

Most cyanobacteria produce extracellular polymeric substances (EPS) that fulfill different biological roles depending on the strain/environmental conditions. The interest in cyanobacterial EPS synthesis/export pathways has been increasing, not only to optimize production but also efficiently redirect carbon flux toward of other compounds, allowing implementation industrial systems based cell factories.
