چکیده    A bacterial culture was isolated from oil-contaminated soil based on its ability to metabolizethe quinoline as the sole source of nitrogen. in this research bacillus licheniformis strain was identified based onthe result of 16s rrna analysis. optimized conditions were obtained with full factorial experimental designmethod using design expert software at temperature: 32oc, agitation speed: 200rpm, quinoline concentration:400 ppm.the efficiency of bacillus licheniformis for biodegradation of quinoline at the optimum conditionswas determined to be 35%. two-phase cultivation media were used with 5, 10, 15 and 20% heavy crude oilconcentration in aqueous media. resting cells of bacillus licheniformis was shown to be capable of removingabout 25% of total nitrogen in 5% heavy crude oil. gc analysis showed a decreasing trend in the activity ofthis strain against crude oil concentration
