Biofilm formation is a complex developmental process. Studying a cyanobacterial model, we uncovered that the cell population within the biofilm is not uniform. A quarter of the cells specialize in robust matrix formation, enabling most of the cells to reside in the biofilm.

The Wonderland of cyanobacterial biofilms: Visualization of  EbfG1::FLAG and EbfG4::FLAG by immunocytochemistry and confocal fluorescence microscopy. Red represents autofluorescence whereas green indicates presence of EbfG1::FLAG or EbfG4::FLAG. Localization of EbfG2 and EbfG3 was not studied yet, however, they form amyloids and are likely part of the biofilm matrix.
