Prominent Pseudomonas aeruginosa colony morphology variants. Cultures of PAO1, MJK8 (RSCV), and PDO300 (mucoid) were streaked on VBMM with Congo red. All strains grow at similar rates, yet MJK8 colonies are small and more aggregative and copious overproduction of alginate is obvious from PDO300. PAO1 has well-defined smooth colonies.
