The paper studies the possible application of salt-tolerant strains of nodule bacteria such as 340b, 348a, 1360, 367a, 363a, 375a for clover and lupine in bioremediation of the soil contaminated by drilling waste in the Tyumen Region. Chemical composition of drilling sludge at the Nivagal’skoe oil field in KMAO (cluster No 924) was determined using XRF analysis, eight types of salinization wereidentified: MgSO4, Na2SO4, NaCl, NaHCO3, Na2CO3, sulfate-soda, sulfhate-chloride, and gypsum. Laboratory studies on nodule bacteria survival were carried out. Inhibiting influence of most salinization types was found, however, all samples have shown positive survival. Moreover, increaseof essential nutrients in the soil was noted. These results indicate that the application of given strains in the remediation of soil contaminated by drilling waste- is possible.
