ABSTRACT: The growth of the microscopic fungi on the solid surface has a great
influence on technical materials destruction. The aim of this study was to
determine the influence of two strains of micromycetesPenicillium palitansstrain6 andArthrinium
phaeospermumstrain 10 on morphological and structural properties of
carbon steel surfaces in the nutrient medium. The difference in consumption of
chlorine byP. palitans6(0.07 wt%) andA. phaeospermum10(0.04 wt%) and the difference in accumulation of a newly formed elementmanganese
forP. palitans6(0.01 wt%) andA. phaeospermum10(0.03
wt%) has been observed. A relation between the surface and interface fungal
stimulated processes, the biotic oxidation of steel surface as well as
formation of the mixed oxides on the biomodified steel surface has been
determined. The morphology of surfaces was characterized by scanning electron
microscopy, the structure—by the X-ray diffraction method, Fourier
transformation infrared and X-ray fluorescence spectroscopy.
