Biodegradation of @entity2555 ( @entity2556 ) by pure laccase has been reported, but the high cost limited its application in environmental bioremediation. Here, we reported a study about @entity2556 degradation by crude extracts (CEs) containing laccase, which were obtained by extracting four spent mushroom (Agaricus bisporus, Pleurotus eryngii, @entity11829 , and Coprinus comatus) substrates. The results showed that @entity10517 , @entity3014 , and @entity9437 were top three degradable @entity2556 by CEs while @entity12683 was most recalcitrant. The @entity2556 oxidation was enhanced in the presence of @entity51351 ( @entity16376 ). Laccase included in CE might play a major role in @entity2556 degradation. The maximum degradation rate of @entity10517 and @entity3014 was observed by using crude extracts from P. eryngii while the highest laccase activities were found in crude extracts from A. bisporus, moreover, crude extracts from P. eryngii, which contained less laccase activities, degraded more @entity10517 and @entity3014 than pure laccase with higher laccase activities. The lack of correlation between laccase activity and @entity2556 degradation rate indicated that other factors might also influence the @entity2556 degradation. Boiled CEs were added to determine the effect on @entity2556 degradation by laccase. The results showed that all four boiled CEs had improved the @entity2556 oxidation. The maximum improvement was observed by adding CEs from P. eryngii. It suggested that some mediators indeed existed in CEs and CEs from P. eryngii contained most. As a result, CEs from P. eryngii has the most application potential in @entity2556 bioremediation.
