Streptomyces rishiriensis is a Gram positive bacterium that produces dark melanin pigments and a number of antimicrobial compounds. You hope to find gene(s) responsible for the production of these melanin pigments. You transform a culture with a plasmid containing a transposon and a kanamycin resistance gene (kanR) and successfully isolate transformed mutants.
