Though highest resistance was observed in Aspergillus niger strain AM1, the three strains of A. niger, received from All-Russian collection of microorganisms (ARCM), showed a higher resistance to white phosphorus than the bacteria. It was shown that exclusion of copper sulfate from the composition of the nutrient medium with white phosphorus does not prevent the growth of fungi. In addition, white phosphorus does not react with the formation of a precipitate and remains for a longer period under these conditions. This fact is a serious argument in favor of biodegradation and has practical applicability in the method of microbial detoxification of white phosphorus. The reasons of resistance to white phosphorus were studied. According to the preliminary data, A. niger AM1’s resistance to white phosphorus is anchored in its genome.
