原始语种摘要: In the present study, an indigenous biosurfactant-producing bacterium, Rhodococcus sp. BAP-1, with effective fluoranthene-degrading ability was isolated from crude-oil contaminated soil. The biodegradation data indicated that Rhodococcus sp. BAP-1 grew well in the presence of 20 mg·L-1 of fluoranthene, whereas in the presence of 150 mg·L-1 of fluoranthene, the biodegradation rate almost remained at low levels. During growth on mineral salts medium, the bacterium could produce biosurfactants. As a result of biosurfactant synthesis, the surface tension of the culture broth was reduced, thus facilitating the contact between the bacterium and hydrocarbon. According to the experimental results, emulsification was probably not the leading mechanism that occurred...
