【 摘 要 】

The aim of this work was to study the potential of fungus strains considered as prospective degraders for the herbicides quinclorac and propanil, for ligninolytic enzyme production. Eight fungal strains were grown in King's B liquid culture medium supplemented with 0.05% Remazol Brilliant Blue R (RBBR) and in liquid culture medium containing wheat bran as substrate. The enzymatic system assessment were: lignin peroxidase, manganese peroxidase and laccases. Results indicated differential patterns of ligninolytic enzyme production; the highest enzymatic activities were related to the production of lignin peroxidase. Among the strains, two (P3SA1F and P11SA2F) showed RBBR discoloration, suggesting the possibility of their application in bioremediation studies.
