Summary:The purpose of this study was to evaluate the influence of oil concentration and inoculum size on pertroleum biodegradation in soil by Nocardia sp. H171-1, isolated from oil-contaminated soil. To investigate the effect of initial oil concentration on total petroleum hydrocarbon degradation, the soil was artificially contaminated with 10, 50 or 100g of Arabian night oil per kg of soil, respectively. Also, it produced 1.35, 4.21, and 5.91 mmol of CO©üper g of soil, respectively. The degradation rate constant of TPH was decreased in proportion to the initial oil concentrations while CO©ü production was increased with the concentration. The growth of Nocardia sp. H17-1 was remarkably inhibited when it was inoculated into sil containing 100g of oill per kg of soil.
