Abstract
The phytotoxic effects of crude oil and components on the growth of red beans (Phaseolus nipponesis OWH1) and corn (Zea mays) was investigated. In addition, the beneficial effects of bioremediation with the oil-degrading microorganism, Nocardia sp. H17-1, on corn and red bean growth in oil-contaminated soil was also determined. It was found that crude oil-contaminated soil (10,000mg/kg) was phytotoxic to corn and red beans. In contrast, obvious phytotoxicity was not observed in soils contaminated with 0-1000mg/kg of aliphatic hydrocarbons such as decane (C10) and eicosane,(C20). Phytotoxicity was observed in soils contaminated with 10-1000mg/kg of the poly aromatic hydrocarbons (PAHs) naphthalene, phenanthrene, and pyrene. It was observed that phytotoxicity increased with the number of aromatic rings, and that corn was more sensitive than red beans to PAH-contaminated soil. Bioremediation with Nocardia sp. H17-1 reduced phytotoxicity more in corn than in red bean, suggesting that this microbial species might degrade PAHs to some degree.
