Retenção de metais pesados em micélio de fungos micorrízicos arbusculares

Bibliographic Details
Title: Retenção de metais pesados em micélio de fungos micorrízicos arbusculares
Authors: Cabral, Lucélia, Siqueira, José Oswaldo, Soares, Claúdio Roberto Fonsêca Sousa, Pinto, José Eduardo Brasil Pereira
Source: Química Nova. January 2010 33(1)
Publisher Information: Sociedade Brasileira de Química, 2010.
Publication Year: 2010
Subject Terms: arbuscular mycorrhiza, biosorption, soil pollution
More Details: This work evaluated the kinetics as well as the retention capacity of Cu, Zn, Cd, and Pb by arbuscular mycorrhizal fungi (AMF) mycelium. The metal retention is a fast process with Cu being retained 3, 30, and 60 times faster than Zn, Cd, and Pb, respectively. Metal retention capacity varied amongst the different tested AMF species and decreased in the following order: Cu>Zn>>Cd>Pb. The Glomus clarum mycelium showed the highest retention capacity for Cu, Cd and Pb, whereas Zn was mostly retained by Gigaspora gigantea mycelium. The simultaneous application of all tested metals in solution decreased Cu and Zn retention by AMF mycelium. The high retention capacity of Cu and Zn by mycelium of G. clarum and G. gigantea suggests a promising use of these isolates in phytoremediation.
