Fig. 12

CVs of graphite electrodes modified with verdigris egg tempera paint films immersed into 0.25 M sodium acetate buffer, pH 4.75, after incubation with: a, b Acremonium chrysogenum (EG@Ac) fungi and c, d Arthrobacter oxydans (EG@Ao) bacteria. Voltammograms before (a, c) and after (b, d) semi-derivative convolution; potential scan rate 50 mV s−1
