Abstract

The present study was aimed to isolate the fungal species capable of tolerating dye pollution. Also the study was conducted to select fungal strain that might be able to remediate the basic fuchsine and congo red dyes from the polluted water. It has been found that the soil treated with different concentrations of basic fuchsine and congo red dyes had shown significant differences in mycodiversity. Soil samples treated with different concentration of these dyes were screened for fungal isolates. Soil fungi were isolated by using dilution plating method and were identified by using two standard manuals of soil fungi. The present research studied the potential of fungal strains, for their tolerance against basic fuchsin and congo red dyes, isolated from dye treated soils for use on removal of dyes. The screening conducted found many strains that presented good tolerant properties, including Aspergillus flavus, Aspergillus niger and Penicillium glabrum that could survive in BF and CR treated soils in a reasonable extent maximum 500 ppm concentration in the present work and their population were isolated throughout the period of study. From the viewpoint of environmental sustainability, the use of such fungal species for removal of dyes from industrial wastewater can be proved as an ecofriendly and cost-effective approach. Depending on the results, the fungal strains appear as efficient candidates for further biotechnological research on the decontamination of dye based industry effluents. For a better remediation, the combined effects of different types of fungi on the growth of other need to be considered during the selection of efficient fungal strains.
