abstract：:Bacterial cytokinesis is driven by the septal ring apparatus, the assembly of which in Escherichia coli is directed to mid-cell by the Min system. Despite suffering aberrant divisions at the poles, cells lacking the minCDE operon (Min(-)) have an almost normal growth rate. We developed a generally applicable screening...
