The degradation of petroleum waste by mixed bacterial cultures which produce biosurfactants: Ralstonia pickettii SRS (BP-20), Alcaligenes piechaudii SRS (CZOR L-1B), Bacillus subtilis (1'- 1a), Bacillus sp. (T-1) and Bacillus sp. (T'-1) was investigated. The total petroleum hydrocarbons were degraded substantially (91 %) by the mixed bacterial culture in 30 days (reaching up to 29 % in the first 72 h). Similarly, the toxicity of the biodegraded petroleum waste decreased 3 times after 30 days as compared to raw petroleum waste. Thus, the mixed bacterial strains effectively clean-up the petroleum waste and they can be used in other bioremediation processes.
