Elevated concentrations of heavy metals in groundwater cause many environmental problems. The present paper reports adsorption behavior of a green bioadsorbent (Trichoderma sp.) for the removal of heavy metal ions from industrial effluents. Sampling of the groundwater within a commissioned landfill site showed contamination of the groundwater with some toxic heavy metals. Fungal biomass of Trichoderma sp.was tested to treat contaminated groundwater and it was found that dried Trichoderma sp. demonstrated significant ability for the extraction of Cd 2+ , Ni 2+ and Cr 3+ ions compared to wet Trichoderma. Fourier transform infrared (FTIR) analysis was conducted on wet and dry biomass before and after treatment to observe the changes in functional groups. In addition, Freundlich and Langmuir adsorption isotherms were used to verify the adsorption performance of Trichoderma sp. The Langmuir adsorption isotherm was found to be a better fit than the Freundlich adsorption isotherm. The maximum adsorption capacities of Ni 2+ , Cd 2+ and Cr 3+ ions on Trichoderma were found to be 0.1353 (pH 4), 0.374 (pH 8) and 0.0527 (pH 10), respectively. The results of removal efficiencies of metal on Trichoderma indicate that it can be successfully applied for the removal and recovery of Cd 2+ , Ni 2+ and Cr 3+ ions from industrial effluents with 100% recovery.

The worldwide interest of the current era is to increase tendency towards the use of natural substances instead of synthetic ones. So, alternative and effective environment friendly sustainable technologies are highly needed. Due to a broad range of biological activities, fungi are considered as a significant source of pigments. Among the fungal species in the soil, the genera of Aspergillus, Fusarium, Penicillium, Paecilomyces, and Trichoderma are dominant. The pigments commonly produced by fungi belong to aromatic polyketide groups such as melanins, quinones, flavins, ankaflavin, anthraquinone, and naphthoquinone. The use of fungal pigments has benefits which comprise easy and fast growth in the cheap culture medium and different color shades being independent of weather conditions and would be useful in various industrial applications. In relation to the toxic effects of the synthetic dyes, the natural dyes are easily degradable since they cause no detrimental effects. Thus, the study of pigments produced by soil fungi has tremendous use in medical, textile coloring, food coloring, and cosmetics.
