Biological Removal of Malachite Green and Congo red by Some Filamentous Fungi

Abstract

Four strains of filamentous fungi were studied to a removal of Malachite green (MG) and Congo red (CR). These fungi were Aspergillus Niger ,Aspergillus flavus , Aspergillus versicolor and P. funigulosum. P. funigulosum showed that decolorization activity was higher than other fungi on solid medium containing MG and CR . The stastical method obtained that there was no significance between fungi . All these fungi were able to degradation dyes to other metabolites . The dry weight ( Biomass) of P. funigulosum reached to 1.10 ,1.02 in mineral salts medium (MSM) with MG and CR respectively , and the stastical methods obtained that there was no significance in dry weights between fungi
