Fig. 2. Comparison of the efficiency of the hydrocarbon-degrading microorgan-
Isms (HDMs) and it coactivity with plant STL (STL-Ms) after 60 days in decreasing
Diesel pollution. Note: Each datum represents the mean 7S.D. of three replicates.
The statistical significance of diesel residual content between HDMs and STL-Ms
Was represented. (*Po0.05, **Po0.01.)
