It is determined that in the oil field regions of the Perm Territory, water and soil samples contain micromycetes of various kinds. Penicillium, Aspergillus, Trichoderma were identified and identified. The effect of micromycetes on steel corrosion was investigated using the fungus resistance method. It was established that the presence of Penicillium, Aspergillus, Trichoderma causes significant corrosion damage to structural carbon steel quality grade St20. The nature of corrosion damage was determined by optical microscopy. It was shown that the areas affected by micromycetes have an uneven nature of corrosion damage with individual point and ulcerative lesions of the St20 surface. The change in the intensity of the growth of micromycetes of various kinds on steel from the time of exposure was established.
