Role of gamma irradiation in modulating 1.1 times more cadmium (Cd) tolerance in Penicillium cyclopium Westling has been detailed in this paper. Augmentation in metal tolerance was recognized by escalation in response to Cadmium and Cd removal efficacies than that of their un-irradiated group. FTIR spectra and electron microscopic photographs further strengthen the role of low absorbed dose of gamma in modulating Cd tolerance in P.cyclopium. Up regulated activities of anti-oxidatives in gamma exposed fungal groups might be the reason for enhanced Cd tolerance than that of their un-irradiated counter parts. This findings reveal a positive and eco-friendly step for heavy metal bioremediation and metal stressed lignocellulosic waste degradation.
