The influence of a direct electric current on the growth, protein secretion, and glucose consumption by Fusarium oxysporum was determined. An electrochemical cell with titanium electrodes was inoculated with F. oxysporum and incubated for 5 days in the presence of 1, 5, and 10mA current densities. The current reduced the fungal growth compared to the control culture. However, protein generation doubled after 3 days. Also, the glucose consumption increased significantly. Finally, the fitness of the growth, protein, and glucose concentration data to the logarithmic and Ludeking-Piret models was respectively investigated, and the effect of electric current on the model parameters was explained.
