ABSTRACT
the present study deal with using two species of fungi, Aspergillus
Niger, Rhizopus oligosporium, in treatment of wastewater to reduce
heavy metals concentrations (Pb, Cd) and some physical and chemical
properties from final discharge of Al nassiryacity .Tow group were
used in this process ,with tow weight from the mention fungi (1 ,2)gm
of each group of fungi with 2 liter of wastewater this group have clone
in laboratory in (25◦) extended for 6 days .The result showed that high
efficiency in reducing the concentration of( cd and pb) by fungi
Aspergillus Niger the percent of removing was 100% more than
Rhizopus oligosporium compare with reducing of some environmental parameters.
Keywords: Aspergillus Niger, Rhizopus oligosporium.
