Amperometric quantification of Alternaria mycotoxins with a mushroom tyrosinase modified carbon paste electrode.

The affinity of mushroom tyrosinase for alternariol (AOH) and alternariol monomethylether  (AME) produced by Alternaria alternata was verified both spectroscopically and electrochemically.  Commercial enzyme and fresh mushroom tissue were employed for electrochemical measurements.  The results demonstrate for the first time that both AME and AOH are substrates for mushroom tyrosinase.  It is concluded that the enzyme has relatively good affinities for both substrates which is a promising result for developing an exzymatic biosensor.
