“…Typical monotonic activity curves are observed for both free and immobilized enzymes as the pH increases from 3 to 7. Such an observation is consistent with the reported impact of pH on fungal laccase activity: this has been attributed to the OHinhibition to T2/T3 copper at higher pH [30,40]. As demonstrated in Fig.…”

“…To identify the protein component of the crude enzyme extract, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was performed on a 13% resolving gel and a 4% stacking gel [30,31]. Protein bands were visualized by Coomassie Brilliant Blue R 230 staining overnight.…”

“…According to the Nernst equation these pH gradients cause high anodic equilibrium potential and/or low cathodic equilibrium potential that significantly lowers the cell voltage and causes a loss of ~60 mV per 1 pH change [1,15]. Fokina et al, 2015 have observed that increase in pH by one unit caused a decrease in oxygen reduction potential in the range of 30-80 mV in a biofuel cell using laccase as cathode catalyst [16].…”

“…Catalases [70,75] contain an iron ion in their active sites and transform H 2 O 2 into oxygen and water [76]. They are involved in the natural degradation of lignocelluloses and also catalyze the oxidation of various organic compounds including phenols, methoxyphenols, aminophenols, and diamines [77]. Fungal UPOs, which have been shown to oxidize aromatic as well as aliphatic compounds contain iron and magnesium ions [32,78].…”
