Diversity of fungal endophytes in Typha latifolia (L.) and their lead biosorption activity

The present study was done to determine the lead (Pb) adsorption capability of endophytic fungi isolated from Typha latifolia (L.), a member of Cattail family (Typhaceae). Wetland plant Typha latifolia (L.) is a well-known pollution indicator, having the ability to absorb and accumulate heavy metals. Twenty fungal endophytes were isolated from different parts of the plant; amongst all isolates, 100% adsorption of lead has been screened in the case of Aspergillus niger A40. Interaction between the fungal biosorbent and metal ion was optimized at contact time of 180 min. As an endophyte, fungi have the potential to remove soil contaminants by enhancing phytoremediation. It may be expected that they may prove good absorbance in case of heavy metal biosorption and waste water treatment.
