[Activation of indigenous micorflora in oil-contaminated soils using photoluminescent films]
Abstract:
A stimulating effect of sunlight transformed by a photoluminescent polymer film on the abundance dynamics and fermentation and respiration of indigenous microflora in oil-contaminated soils was investigated. Polymer film doped with photoluminophores based on inorganic Eu-complexes and common glasshouse film was used as a cover material for oil-contaminated soils at experimental and control sites. The application of photoluminescent film has been reported to stimulate a hundredfold growth of the microflora population, with the soil respiration intensity and catalase activity being increased by a factor of 2.5-3, respectively. The extents of biodegradation of petroleum hydrocarbons within 60 days were up to 70 and 30% of the overall background pollution level for the experimental and control site, respectively. Residual hydrocarbons extracted from samples of the contaminated soils were analyzed by infrared spectroscopy to show the appearance of additional absorption bands at 3350, 1600, and 1710 cm(-1), thus indicating the formation of metabolites during enzymatic oxidation of oil. Chromatographic data corroborated the occurrence of intense oxidation. The hydrocarbon biodegradation factor increases sixfold when the photoluminescent films are used.
