TOXIC METABOLITES OF ENTOMORPHTHORIC FUNGI FROM CULTURE COLLECTIONS AND PRELIMINARY SELECTION OF ACTIVE MONOCONIDAL ISOLATES OF ENTOMOPHTHORA-THAXTERIANA PETCH (ZYGOMYCETES, ENTOMOPHTHORALES)

Study of collections strains of Entomophthorales from the collection o f VIZR, as well as monoconidial isolates have been performed. The foll owing parameters were analyzed: yield of biomass (Bm), content of toxi c compounds in biomass (By), biological effectivity (A) and technologi cal characteristics: yield of toxic compounds (Yt), general productivi ty (P). The ability to produce toxic metabolites while long-term culti vation on artificial growth media has been revealed for all studied sp ecies, strains and monoconidial isolates. It was shown that isolates w ith high productivity were more promissing for future selection of str ains with the increased ability of toxic production.
