Descripción
The fluoranthene degradation was predicted by the sorption/desorption process as its fungal transformation was in relationship with the bioavailabit. Toxicants availability is significant to assess as their bioremediation and persistence in the contaminated environment depended on the physical, chemical and textures of the polluted sediments that fixed the organic xenobiotics. In most of natural and man-made habitats, the aromatic hydrocarbons had been found sorbed to soil particles that inmobilized the compounds and diminished the microbial attack. Therefore, wild yeasts from hydrocarbon polluted areas were isolated, and their potential as fluoranthene degraders were evaluated in different texture soils and organic matter contents. Hansenula angusta and Rhodotorula minuta were isolated from industrial effluents and used in desorption experiments; the obtained Flu uptake parameters explained the efficiency of both yeasts to biotransform Flu sorbed to soil particles. H. angusta and R. minuta degraded Flu by bioemulsifiers production; evenmore, they were highly efficient to uptake fluoranthene in the biphasic cultures and were dominant in the sampled polluted sediments. The potential application of biosurfactants produce by indigenous yeasts in PAHs recovery from the polluted environments was demonstrated by the percentage of fluoranthene removal and by the stability of the surface tension.
