Monitoring of bioremediation of soil polluted with diesel fuel applying bioassays

Results of bioassays performed in Department of Microbiology and Environmental Biotechnology as well as statistical analysis point out to significant interdependence among decreasing amounts of diesel fuel in a soil and a germination level of spring barley (Ortega cv.) seeds, length of above ground parts of seedlings and their root system length. Calculated values of resistance indices (RI) express high susceptibility of spring barley towards diesel fuel presence in a soil and potential possibility to utilize the plant as a bio-indicator of changes occurring during remediation of soil polluted with diesel fuel.
