Chemically defined media for competence factor (CF) production by group H Streptococcus strain Challis-6 are described. CF is produced by noncompetent cells in a glutamate-free medium in which the cells cannot attain competence and by cells prior to

Stable auxotrophic mutants of a group H streptococcus (strain Challis) were isolated on a modified Mickelson defined medium after exposure to N -methyl- Ń -nitro- N -nitrosoguanidine. Such mutants were transformed to both prototrophy and streptomyci

A procedure for the isolation and purification of competence factor produced in a defined medium by group H streptococci, strain Challis-6, is presented. Partial characterization and chemical analysis of the product are described. The procedure yield
