The initial concentration of total petroleum hydrocarbons (TPHs) in the soil was 6380 μg.g-1 dry weight. An amount of 200 kg soil was inoculated with 1.5 L of the bacterial preparation GEM-100 containing Pseudomonas sp. and Acinetobacter sp. strains (5.3*1010 CFU.ml-1) adapted to diesel fuel. The concentration of TPHs in the soil decreased by 65.5 % after bioremediation. Different organisms such as the bacterium Vibrio fischeri, terrestrial plants Sinapis alba, Lactuca sativa, Hordeum vulgare, water plant Lemna minor, earthworm Eisenia fetida and the crustacean Heterocypris incongruens were used for ecotoxicity evaluation. The highest toxicity was detected in the first period of bioremediation. However, certain toxic effects were detectable during the whole bioremediation process Workplace Institute of Microbiology Contact Eliška Spurná, eliska.spurna@biomed.cas.cz, Tel.: 241 062 231 Year of Publishing 2008
