Fermentation Broth of actinomycetes with insecticidal activity

摘要

Claim 1: a composition characterized in that it comprises a liquid or a Solid fermentation with insecticidal activity of an actinomycete, fermentation Broth or solid comprising an optimized ratio between the active and the inactive dunaimicinas dunaimicinas.Claim 2: the composition of claim 1, wherein the optimized ratio between the active and the inactive dunaimicinas dunaimicinas is at least approximately 1: 1. Claim 2: the composition of claim 1, characterized in that it is a Strain of the actinomycete Streptomyces sp. capable of producing both Active and inactive dunaimicinas dunaimicinas.Claim 1: a process for producing a fermentation Product enriched in dunaimicinas with insecticidal activity, characterized in that it comprises growing an actinomycete which produces dunaimicinas dunaimicinas Active and inactive in a Culture Medium containing carbon sources and F Sources of Nitrogen, until they are at least approximately 0,Active dunaimicinas 5 milligrams per Liter of Culture medium, where the ratio between carbon sources and Nitrogen is at least approximately 10: 1 by weight.
