Chromium Biosorption Potential of Alternaria Brassicae Cr04 Isolated From Effluent Sample

Kirupa S, Sumithra, P, Benila smily, J. M


In the present investigation, ten chromium resistant fungi were isolated from the tannery effluent collected from Trichy, TN, India. The isolated fungi were screened for their heavy metal resistance pattern by growing in increased concentration of chromium. The strain CR04 which resists upto 6 mg/ml concentration of chromium was selected for chromium biosorption studies, the strain was identified as Alternaria brassicae using 18S rRNA sequence analysis. The A. brassicae strain CR04 was mass produced and dead fungal biomass was harvested for biosorbent preparation. The dead fungal biomass of A. brassicae strain CR04 was found to be efficient in the biosorption of hexavalent chromium. The biosorbent formulated could be used in the environment cleanup of heavy metals inn near future.
