The reaction of soil microorganisms to the contamination of soil artificially polluted with @entity2555 ( @entity2556 ) was evaluated in pot experiments. The plant used in the tests was cock's foot (Dactylis glomerata). Three different soils artificially contaminated with @entity2556 were applied in the studies. Three selected @entity2556 ( @entity10517 , @entity11966 , and @entity9435 ) were used at the doses of 100, 500, and 1000 mg/kg d.m. of soil and diesel fuel at the doses of 100, 500, and 1000 mg/kg d.m. of soil. For evaluation of the synergistic effect of @entity1568 fixing bacteria, the following strains were selected: associative Azospirillum spp. and @entity4190 stutzerii. Additionally, in the bioremediation process, the inoculation of plants with a mixture of the bacterial strains in the amount of 1 ml suspension per 500 g of soil was used. Chamber pot-tests were carried out in controlled conditions during four weeks of plant growth period. The basic physical, microbiological and biochemical properties in contaminated soils were determined. The obtained results showed a statistically important increase in the physical properties of soils polluted with @entity2556 and diesel fuel compared with the control and also an important decrease in the content of @entity2556 and heavy metals in soils inoculated with Azospirillum spp. and @entity4190 after cock's foot grass growth. The bioremediation processes were especially intensive in calcareous rendzina soil artificially polluted with @entity2556 .
