The biodegradation process is essentially controlled by the pH of
the medium. The variation of pH values during the ITE treatment
process using C. globosum is presented in Fig. 4b. The pH values
increased from 5.5 to 7.9 and 6.2 after 24 h of incubation and
reached final values of 9.05 and 8.7 for stirred and static cultures,
respectively. The pH increase was followed by a rise of the decolourization
yields and CODs removal efficiencies (Fig. 4c and d). As
observed by Dirk et al. (2003), the fungus produces organic
