Abstract

Abstract In response to light regime changes, the model cyanobacterium Synechocystis sp . PCC 6803 can switch from a planktonic lifestyle to form a phototrophic biofilm. Its planktonic cultures contain single cells and microcolonies, while the formed biofilms are dominated by cell aggregates with remarkable heterogeneity. We fitted the size distribution of the latter with a log-normal function and found that under low-to-moderate light intensities (
