title: [Effect of population density on Actinomyces resistomycificus biosynthesis of heliomycin and resistoflavin].
abstract: Determination of heliomycin and resistoflavin contents in colonies of Act. resistomycilicus grown on pads with different density showed that the population density may be a factor controlling the level of the antibiotic biosynthesis by Act. resistomycificus and directing it along production of heliomycin or resistoflavin.
