Abstract

• The present study was carried out to investigate metal resistant and adsorption strain. A chromiumresistant fungus M-1 was isolated from soil sample by conventional plating method. The isolated fungus was studied on the basis of morphological, microscopical characteristics and identified with the help of literature keys of Ando (2016). According to morphology and distinct characters, the fungal strain was identified as Paecilomyces sp. The fungal growth in metal resistant against Cr6+ ion at different concentration of 10 mM, 20 mM, 30 mM, 40 mM and 50 mM was studied. It was observed that Paecilomyces sp. was found to be resistant against 50 mM of Cr6+ ion. The biomass of chromium-resistant fungus was used for biosorption experiment by varying contact time and biomass dose. The biosorption of Cr6+ ion from industrial wastewater by chromium- resistant biomass showed 45.48 % removal and 1.9058 mg g -1 of Cr6+ ion at optimum contact time 8 h and biomass dose 0.4 g respectively. From the results, that Paecilomyces sp. showed chromiumresistant behaviour and biosorption potential for removal of Cr6+ ion from industrial wastewater.
