Abstract

The research investigated the capacity of rice husk for stimulating bioremediation of chromium polluted soil. Various levels of Cr (VI) polluted soil, ranging from 10 to 90 mg/Kg were amended with rice husk. The treated media composed of husk/soil ratio of 0.40 and 0.15. In the presence of C/N ratio of 70% higher than initial level, indigenous microbes grew up 3 times higher than their initial numbers during the first two weeks. At the same period, chromium removal increased sharply. Rice husk brought about increasing removal half time (t-50) for microbes and t-50 decreased for chromium removal.
