title: [Isolation and properties of a biostimulator formed by yeast-like fungi and its effect on levorin biosynthesis].
abstract: Experiments on isolation of active substances or biostimulators from the culture fluids of yeast-like fungi of Candida (C. tropicalis, strain 159) were performed. Addition of the biostimulators to the fermentation medium for cultivation of the levorin-producing actinomycete provided the same levels of the antibiotic synthesis as mixed cultivation of the actinomycete and C. tropicalis. The biostimulators were found to be thermostable and stable within a wide pH range (2.0--14.0). They are low-molecular compounds of the organic nature.
