title: [Secretion of substances by different actinomycetes which induce sporulation by an asporogenic mutant of Streptomyces griseus].
abstract: The asporogenic mutant of Streptomyces griseus 1439 sporulates under the action of factor A, a regulator of differentiation, liberated by the parent strain. It has been found that 11 out of 30 cultures belonging to various species of actinomycetes induce formation of spores in strain 1439. The response of this strain to each of the 11 strains of actinomycetes has shown that they liberate stimulating substances in different quantities and at different periods of time.
