Mechanism of Biosorption of Pb (ii) and Cu (ii) ions using Dead Biomass of Fusarium equiseti strain UMAS and Penicillium citrinum strain UMAS B2

Filamentous fungi such as Fusarium equiseti KR706303 and Penicillium citrinum KR706304 are capable of sequestering heavy metals from aqueous solutions. In the present study, the role play by various functional groups present in the cell wall of F. equiseti KR706303 and P.citrinum KR706304 during lea...
