REMOVAL OF Cr (VI) from NORKRAN’S LIQUID MEDIUM USING Aspergillus fumigatus and Rhizopus sp.

Soil and water pollution caused by heavy metals can result in health challenges such as cancer. Therefore, this study was aimed at testing the ability of Aspergillus fumigatus Rhizopus sp. isolated from cassava grinding mill environment to reduce, bio-accumulate tolerate Cr (VI) Norkran’s medium. Fungal isolates were obtained soil samples using 2 % malt extract agar. reduction potential fungal cells done shake flask method. The tolerance different concentrations used for bio-sorption experiment determined collecting 1 ml sample each experimental on days 0, 5, 10 20 followed inoculation agar plates. adapt increasing ascertained inoculating mycelial ball amended with 16.1 mg/L (VI).
