Abstract: The presented study compared the growth of Aspergillus niger strain AM1 in culture media varying in composition but containing P4 as the sole source of phosphorus. Comparing the compositions of the media and the growth rate of Aspergillus in them, we found a key component that is a favorable factor for the growth of AM1 and the biodegradation of white phosphorus. This component was sodium nitrate (NaNO3 ). It has also been shown that copper sulphate (CuSO4 ) has no effect on the growth of Aspergillus in media with white phosphorus, regardless of the composition of these media.
Index terms: white phosphorus, Aspergillus niger АМ1, culture mediums, growth factors, morphological description, taxonomy.
