    Mineral oil spill, especially waste-crankcase oil affects the soil which remains bereft of fertility for a long time. In the present study, an approach to soil bioremediation, based on application of mixed algal culture was described. Cyanobacteria and algae release oxygen in the soil and increase the rate of abiotic processes of oxidation which destroy the pollutant to harmless products. The released oxygen is also of use to the roots of higher plants in the polluted soil. The algal extracellular organic substances are a useful substrate for the soil bacteria and fungi which metabolize the pollutant. Seed germination, plant growth and development in oil polluted soil, watered with mixed algal culture, were quantified using Tribulus terrestris as an experimental plant. The plant growth parameters were very low at 5 % of heavy diesel fuel in the polluted soil, whereas up to 1 % of waste-crankcase oil was overcome. In case of higher pollutant concentrations the remediation required addition of sand, soil or compost.
