Abstract – The results of examining biodegradation of a hazardous toxicant – white phosphorus are presented, which confirm a hypothesis of involving elemental phosphorus into natural cycle of biogenic elements. The involvement of white phosphorus in the biomass of growing microorganisms after their inoculation into culture media containing white phosphorus as the single source of phosphorus has been reliably demonstrated for the first time. It has been shown that microorganisms of different taxonomic groups (i.e. bacteria, mold fungi, streptomycetes) exhibit different kinds of resistance to white phosphorus in the course of its biodegradation. A hypothetical scheme is proposed for biodegradation of white phosphorus in the open environment.
