Assessment of growth of Fusarium solani by cyclic voltammetry and possiblebioanalytical applications

Fusarium solani, the fungus isolated from polyurethane waste scraps, was st udied for its voltammetric response. The peak current values were obtained for different days and were plotted against time. This electrochemical meth od based on the voltammetric response showed all the four phases of the gro wth of the fungus. The growth curve obtained matched well with the conventi onal methodology, which is obtained by assessing the increase of dry weight of the organisms against time. The electrochemical method is more advantag eous than the conventional method because the conventional method is very t ime consuming and difficult to work with. Further, the electrochemical meth od clearly shows the decline phase, which is generally not very well define d in the conventional method of assessment of the growth curve. It was conf irmed by further experiments that the metabolites were responsible for the anodic peak and not the fungal biomass. Identification of the metabolites t hat are responsible for the anodic peak is presently being studied.
