CGXII culture supernatants and the MEK700 wild type culture (OD600 = 8) were not diluted before staining (5 µl supernatant or culture + 5 µl nigrosin dye). CGXII cultures were diluted with H2O to an OD600 of 1.5 prior to staining. CGXII wilt type culture was diluted to an OD600 of 8 prior to staining.
