摘要: Rhodococcus erythropolis M-25, one of the representative biosurfactant producers, performed effectively during biodegradation four crude oil. The microbial degradation efficiency is positively relevant to API chemical dispersant Corexit 9500A did not enhance petroleum hydrocarbons experimental period. 70.7% N-4 oil was degraded after 30days, while in plus sample removal 42.8%. Corexit-derived compounds were metabolized by M-25 at same time biodegrading. Neither nor dispersion process has almost no effect on biomarker (m/z=231). saturated methyl-branched fatty acids increased from 37.3%, 49.4%, when exposed with Similarly, membrane N3-2P 20.25% 44.1%, it
