Trichoderma is one of soil fungi that has been widely explored for the removal and recovery of heavy metals. A preliminary experiment was set to investigate the potential of two local species of Trichoderma, T. harzianum and T. virens , to remediate silver nanoparticles (AgNPs) contamination. AgNPs was studied as they have the most commercial applications as consumer products and accumulated in soil. Four levels of AgNPs (0, 100,200,300 mg L −1 ) were used to examine the ability of each species to grow in contaminated media. The growth of Trichoderma spp. was observed by measuring the colony diameter and spore production. The results showed that T. harzianum was more sensitive to AgNPs than T. virens as the colony diameter and spore production reduced significantly. The study indicates that T. virens has a potential to remediate AgNPs contamination.
