Bioremediation of Chromium from Fortified Solutions by Phanerochaete Chrysosporium (MTCC 787)

Sumit Pal and Vimala Y

Pollution by chromium is of major concern as the metal is used in electroplating, metal finishing leather tanning and chromate preparation. Chromium found in water bodies and in soil is in the form of Cr (III) and Cr (VI). Cr (VI) being of particular concern because of its greater toxicity. At present various microorganisms are used for bioremediation of heavy metals from soil and water bodies. The aim of present work was to bioremediate chromium from fortified solution by a white rot fungus Phanerochaete chrysosporium (MTCC787). The potency of Phanerochaete chrysosporium was evaluated to remediate chromium from fortified solution by viable cells, microbial biosorbents and immobilized cells for the first time. The percentage removal of chromium was analyzed by UV-Visible spectrophotometer (HitachiU-2900). The study shows 99.7% Cr (VI) was removed by biosorption with Phanerochaete chrysosporium detected spectrophotometrically after 72 hrs. This study shows that Phanerochaete chrysosporium is highly potential to be used for the removal of chromium which is also a viable, eco friendly and cost effective technology for cleanup of chromium (VI).
