Effect of Metal on Soil Mycobiota


Present investigation were conducted to evaluate the influence of chromium contamination on soil mycobiota and to obtain some Cr resistant strains for the management of Cr contaminated soils and of the effluents carrying the metal. Each pot was treated with different concentrations (50 ppm, 100 ppm, 250 ppm and 500 ppm) of chromium sulphate solution separately in triplicates. Three pots served as control with each concentration. The soil samples collected aseptically from control and treated pots after 30, 60 and 90 days were analyzed for mycobiota using serial dilution method. Overall dominance of Aspergillus sp. was observed amongst the 43 species of fungi isolated. A. fumigatus was most tolerant to Cr probably due to binding of Cr by certain groups on the fungus as revealed by FT-IR spectroscopy. Chromium sulphate adversely affected the mycobiota qualitatively as well as quantitatively. Soil fungal diversity is also adversely affected by Cr contamination. A. fumigatus biomass with Cr binding functional groups might be utilized for in-situ management of Cr in soils and in biosorption based effluent treatment systems.
