A total of 47 cultures of Aspergillus representing 13 species were screened for their ability to tolerate 7.5 mM Pb2+ and 2 mM Cu2+, all of which were positive, with growth of 31 of the cultures being enhanced by low concentrations of lead. The isolates of Aspergillus versicolor, A. niger and A. flavus were tolerant to concentrations as high as 10 - 12.5 mM Pb2+ and 3 – 4 mM Cu2+. Selected cultures displayed a good sorption capacity of 32 - 41 mg Pb2+ and 3.5 - 6.5 mg Cu2+ g-1 dry weight of… Expand

Isotherm and kinetic models and cell surface analysis for determination of the mechanism of metal sorption by Aspergillus versicolor
TLDR
Fourier Transform Infrared, scanning electron microscopy and EDAX analysis indicated that metal removal from solution by A. versicolor occurred by a passive adsorption to the fungal cell surface, involving an ion exchange mechanism. Expand
Copper biosorption from an aqueous solution by the dead biomass of Penicillium ochrochloron
TLDR
The results evidenced that the dead biomass of P. ochrochloron has a great potential as a biosorbent to remove copper from an aqueous solution and could be explored for the development of the environmental recovery process. Expand

Bioremediation of Metallic Ions by Eight Penicillium Species
AbstractIn this paper, eight Penicillium species (P. brasilianum, P. citrinum, P. funiculosun, P. janczewskii, P. janthinellum, P. mineoluteum, P. pinophilum, and P. sclerotiorum), isolated fromExpand
Assessment of Ni accumulation capability by fungi for a possible approach to remove metals from soils and waters
TLDR
The achieved results demonstrate the high Ni(II) tolerance, up to 500 mg Ni l−1, and removal capability of a Trichoderma harzianum strain, suggesting its possible use in a bioremediation protocol able to provide a sustainable reclamation of broad contaminated areas. Expand
Diverse Metabolic Capacities of Fungi for Bioremediation
TLDR
The multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, laccases, peroxidases and cyrochrome P450 monooxygeneses are discussed. Expand
Metal resistance of halotolerant fungi from mangroves and salterns of Goa, India
TLDR
Amongst the isolates obtained, those of Aspergillus having a radiate, biseriate spore arrangement, and the single triverticillate morphotype of Penicillium displayed a higher degree of resistance to heavy metals, suggesting that mechanism of resistance in these fungi could be phylogenetically related.
