Streptomyces coelicolor is a soil actinomycete bacteria used at the John Innes Centre on the Norwich Research Park as a model organism to understand different aspects of antibiotic production. In this example, S. coelicolor expressing the ß-glucuronidase reporter gene is being grown in the presence of paper discs contain different antibiotics. The intensity of the blue/green colour indicates the level of response of the promoters to the presence of the antibiotic. Yellow/brown squares represent conditions in which the promoter does not respond to the presence of these compounds.
