Purine Auxotrophic Mutants with Altered Spore Color in Streptomyces azureus. ATCC 14921

Microbial Genetics Division, Institute of Genetic Resources, Faculty of Agriculture, Kyushu University, 46, Higashi-ku, Fukuoka 812, Japan

ABSTRACT

A purine auxotroph with pale purple spores and a derivative with yellowish orange spores were obtained from the wild-type strain of Streptomyces azureus ATCC 14921, which has bluish green spores. The changed color or pigmentation in the mutants was limited to the spores. They accumulated AIR (5'-phosphoribosyl-5-aminoimidazole) due to the lack of AIR carboxylase activity.
