(A-C) Colonies formed by genetic variants of Pseudomonas aeruginosa strain PA01 on the surface of a nutrient agar pad. Images courtesy of Yasuhiko Irie, University of Dayton. (A) A colony formed by the standard (non-mutated) version of this strain. (B): A “mucoid” colony formed by a strain that overproduces extracellular polymeric substances. (C) A “rugose” colony formed by a “rugose small colony variant” (RSCV) strain. RSCV strains often show increased levels of the intracellular signalling molecule cyclic di-GMP.
