ABSTRACT

The objective of the study was to determine the rate of growth and cytotoxicity
of mycelium of fungus-like organisms Saprolegnia parasitica on media with
variable form of available carbon and nitrogen (Sabouraud Dextrose Agar (SDA),
Malt Extract Agar (MEA), Potato Dextrose Agar (PDA), Czapek-Dox Agar (CDA)) in
magnetic field of 1, 5 and 10 mT. The growth rate of S. parasitica in
magnetic field was most varied on SDA medium: the mycelium growth was the slowest
in the field of 5 mT compared to the remaining experimental variants and to the
control. On MEA and PDA media the growth rate did not vary among the tested field
values and the control. The kind of medium and magnetic field had an effect on
cytotoxicity of S. parasitica – on SDA medium the mycelium cytotoxicity
was reduced to the greatest extent in magnetic field of 5 mT. The phenomenon
can be used to increase the effectiveness of stocking material production.

Key words: Saprolegnia parasitica, fungus-like organisms, magnetic field, microbiological medium, cytotoxicity.
