Abstract
The colored dye effluents are considered to be highly toxic to the
aquatic biota and reducing photosynthetic activity, which disturbs the
natural equilibrium. The direct disposal of textile industry wastes was
repeatedly described as a threat to the environment.
Since recent technologies designed for waste management and
environment cleanup program are based on the bioremediation of different
pollutants by soil and water microflora. Thus the present work discussed
the role of fungi in bioremediation and removal of textile dyes from wastes
of textile industries. The results could be summarized as follows:
Six fungal species were isolated from a mixture of 4 weeks incubated
soil samples and wood chives. These fungi were identified as Aspergillus
flavus, Aspergillus niger, Penicillium canescens, Penicillium crustosum,
Penicillium sp., and Fusarium sp.. It was obvious that Aspergillus flavus
and Penicillium canescens possessed the highest decolorization activity.
Hence these isolates were chosen for further investigation.
- Optimization studies revealed that Czapek’s Dox medium, 0.01% Direct
Blue dye concentration, incubation temperature 30 °C and 35 °C for 7 days
and pH4 and 5 were the best conditions for dye decolourization by
Aspergillus flavus and Penicillium canescens, respectively.
