ABSTRACT
The preparation avercom created on the basis of ethanol extracts from the biomass of Streptomyces avermitilis UCM Ac-2179, contains an antiparasitic antibiotic avermectin, as well as a complex of biologically active substances: amino acids, lipids, including nonsaturated fatty acids, and phytohormones, particularly: auxins, cytokinins, hybberellins. The above mentioned complex is characterized by nematocidical, phytostimulating and elicitor effect upon plants which has been confirmed with the results of production experiments on the cucumber variety Angelina.

Systematic position of 49 cultures from Ukrainian Collection of Microorganisms (UCM) has been revised using the computer program StmID. Forty five cultures retained their species status but 4 cultures received the new species. Authors make a critical estimate of the program work and propose some recommendations for users.

The possibility of Streptomyces cultures preservation in the atmosphere of argon, nitrogen, carbon dioxide and free air (the latter as a control) has been first studied. The possibility of short-term (4-6 months) preservation of Streptomyces cultures in the atmosphere of argon and nitrogen has been demonstrated. Some cultures could be preserved in the argon and nitrogen atmosphere for 26 years.
