Abstract
This study aimed to isolate and identify the species Ochrobactrum anthropi and Pseudomonas putida as indicators for measuring lead absorption and degradation of anthracene in laboratory conditions. The results showed that the mentioned species could grow well in 50 mg/l of lead and 30 mg/l of anthracene. The maximum growth at concentrations of 50 mg/l of lead and 30 mg/l of anthracene was measured 1.39 and 0.530, respectively. The results of the study of the ability of lead uptake by O. anthropi at a concentration of 50 mg/l and anthracene removal by P. putida at a concentration of 30 mg/l indicated that the mentioned bacteria started absorbing lead and anthracene at the time of inoculation and quickly reduced their concentrations in the solution. Removal of lead and anthracene by Ochrobactrum anthropi and Pseudomonas putida from the metal and hydrocarbon solutions continued actively till the final moments of measurement and at the end of the experiment, 84% of lead and 77.986% of anthracene were removed.
