Spills involving fuels and lubricating oils in industrial environments caused by the fueling of machines, inadequate storage washing equipment are significant sources environmental pollution, impacting soil water bodies. Such incidents alter microbiological, chemical physical properties affected environments. The use biosurfactants is an effective option for cleaning tanks remediation contaminated soils effluents. scope this work was to assess production application a Starmerella bombicola ATCC 22214 biosurfactant remediate marine terrestrial environment polluted oil. optimized terms carbon/nitrogen culture conditions using flasks. performance tested clayey soil, silty standard sand, as well smooth surfaces effluents with (fuel B1 thermal power generation, diesel, motor oil). ideal medium contained 2% glucose 5% glycerol, agitation at 200 rpm, fermentation 180 h inoculum, resulting yield 1.5 g/L. had high emulsification indices (86.6% oil 51.7% diesel) exhibited good stability under different pH values, temperatures concentrations NaCl. critical micelle concentration 0.4 g/L, surface tension 26.85 mN/m. In tests, enabled removal no less than 99% from types soil. results showed that produced promising agent derivatives, especially treatment oily
