A bacterial colony of Streptomyces coelicolor growing on milk powder agar. This bacteria make a blue pigmented antibiotic called actinorhodin which can be seen, secreted into the colony's surroundings, and in combination with the colour of the agar, appears darker than the typical sky blue. Much research at the University of East Anglia, in collaboration with the John Innes Centre, has been centred around this fascinating and remarkable micro-organism and related actinomycetes to better understand their basic biology and to uncover new antibiotics.
