摘要：Zinc and mercury are causing a problem worldwide owing to highly toxicity and this problem will intensify if obligatory actions not taken. In present study searching about bioactive fungal strain can. We screened ten endophytic fungal species derived from different plants grow in polluted sites for tolerating and removing both zinc and mercury efficiently from aqueous solutions. Among these isolates Aspergillus. tubingensis Merv4 showed the highest resistant toward mercury (Hg2+) with the highest tolerance against zinc (Zn2+). Moreover, simultaneously it was tolerant to different other toxic metals like pb2+, Cr6+, Cd2+ and Ni2+ with varied degree of resistant. Dead biomass of A. tubingensis Merv4 strain showed capable of totally removing (100%) of both zinc and mercury, respectively from aqueous solution under optimized conditions. In real industrial disposal water the maximum removal values of zinc and mercury were (96% and 91%, respectively) by dead biomass of A. tubingensis Merv4 under optimized conditions. In near future these promising fungi can be used in bioremediation of mercury, zinc and other metal contaminates from industrial wastewaters onto microbial dead biomass.
