The growth of microorganisms of various taxonomic groups (fungi, streptomyces and bacteria) was
observed for the first time in culture media containing white phosphorus P4 as the source of phosphorus. This is the
first known example of the incorporation of white phosphorus into the biospheric circulation of the phosphorus
element. The highest concentration applied in this study exceeds the Threshold Limit Value (TLV) of white
phosphorus in wastewater by 5000 times, and in drinking water by up to 100,000,000 times! The growth selection of
cultures resistant to P4 was carried out for the first time. We identified the microorganisms, growing on white
phosphorus, as new strains of Aspergillus niger and Streptomyces sampsonii. The number A. niger AM1 and S.
sampsonii A8 were assigned to them, respectively. Strains of the A. niger isolates were shown to better adapt to P4
than the bacteria.
