AIMS: Soil @entity3494 (As) contamination of food-chains and public health can be mitigated through fungal bioremediation. To enumerate culturable soil fungi, soils were collected from the As-contaminated paddy fields (3-35 mg kg(-1) ) of the middle Indo-Gangetic Plains. METHODS AND RESULTS: Total 54 fungal strains were obtained and identified at their molecular level. All strains were tested for As tolerance (from 100 to 10,000 mg l(-1) @entity9491 ). Fifteen fungal strains, tolerant to 10,000 mg l(-1) @entity9491 , were studied for As removal in-vivo for 21 days by cultivating them individually in @entity415 dextrose broth enriched with 10 mg l(-1) As. The bioaccumulation of As in fungal biomass ranged from 0  023 to 0  259 g kg(-1). The biovolatilized As ranged from 0  23 to 6  4 mg kg(-1). CONCLUSIONS: Higher As bioaccumulation and biovolatilization observed in the seven fungal strains, @entity12799 FNBR_L35; Fusarium sp. FNBR_B7, FNBR_LK5 and FNBR_B3; @entity14940 FNBR_LK1; Rhizomucor variabilis sp. FNBR_B9; and @entity14940 sp. FNBR_BA5. These fungal strains were also tested and found suitable for significant plant growth promotion in the calendula, withania and oat plants in a greenhouse based pot experiment. SIGNIFICANCE AND IMPACT OF STUDY: These fungal strains can be used for As remediation in As-contaminated agricultural soils.
