The paper presents biological removing of Cr(VI) ions from aqueous solution by applying autochtonic fungi seedling of Trichoderma viride and Rhizopus oryzae originated from chromium-ore waste effluents. The growth of organism and removing of chromium (VI) was performed in aqueous solution of various chromium (VI) contents and at optimal value of pH. The optimumpH of Trichoderma viride and Rhizopus oryzae growth was 4.5 and 7.The maximum Cr reduction efficiency of 95.116% and 91.29%., biomass growth was achieved at temperature 30oC and 37oC,with an initial Cr6+concentration of 500 and 400 ppm and incubation period of 72 hours. Since removal of chromium(VI) from aqueous solution may occur because of reduction, bio-sorption or bioaccumulation processes, to determine which one occurred, the Cr(III) contents were determined in samples of the medium as well in ooze after mycelium irrigating and in mycelium, However, Cr removal via uptake by the two fungal biomass was observed to be the range of 0.51.78% only, for all the concentration applied, which is insignificant when compared with the initial Cr concentration in the culture medium
