Serratia marcescens can form brilliant red colonies on LB agar due to the synthesis of the secondary metabolite prodigiosin. In the Microbiology teaching lab, we had students create pigment mutants of S. marcescens and these lovely shades of pink and white were collected for analysis. Read More
Streptomycetes are a member actinomycete family. Streptomycetes are usually found in soil and are important decomposers. They are aerobic, gram-positive, filamentous rods that create branching hyphae. They also produce more than half of the world's antibiotics, and are therefore very valuable in... Read More
