White phosphorus P4 is one of the most dangerous pollutants of the environment. Nevertheless, it is used in industry and for military purposes, so it cannot be ruled out that this substance is exposed to the environment. Consequently, methods of detoxifying P4 are needed, including biological means. For the first time, we have successfully cultured microbes (mold fungus of the genus Aspergillus) in a medium containing P4 as the sole source of phosphorus. In this novel medium, the microorganism grew and did not experience phosphorous starvation (Fig.). That is, the fungus oxidized white phosphorus to phosphate, which is a primary necessity for life! Aspergillus grows in a medium with white phosphorus concentration of up to 1%. This exceeds the TLC of P4 in wastewater by about 5000 times! Across the Globe, this is the first example regarding the inclusion of white phosphorus into the biospheric cycle of elemental phosphorus. We identified this microorganism as a new strain of A. niger. The strain was designated as A. niger AM1. The nucleotide sequence of the strain is published in the GenBank database, where it is assigned the number KT805426.
