Microbes and enzymes: the future for bioremediation of PAH-contaminated soils ?
soils polluted with polycyclic aromatic hydrocarbons (PAHs), suggests a new review of remediation approaches. However, risk assessments and further work are needed before their use can be extended beyond the lab to realworld situations. This comprehensive overview of available and novel methods indicates their constraints and potential for future development and research. 10 August 2017 Issue 4...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons by Aerobic Mixed Bacterial Culture Isolated from Hydrocarbon Polluted Soils
In this study, the degradation potential of five polycyclic aromatic hydrocarbons (PAHs) by aerobic mixed bacterial cultures was investigated. Microorganisms were isolated from hydrocarbon contaminated soils of Shadegan wetland located in southwest of Iran. The degradation experiments were conducted in liquid cultures. PAH or PAHs concentration was 100 mg/L at the beginning of degradation e...
متن کاملA review on slurry bioreactors for bioremediation of soils and sediments
The aim of this work is to present a critical review on slurry bioreactors (SB) and their application to bioremediation of soils and sediments polluted with recalcitrant and toxic compounds. The scope of the review encompasses the following subjects: (i) process fundamentals of SB and analysis of advantages and disadvantages; (ii) the most recent applications of SB to laboratory scale and comme...
متن کاملEffect of toluene as gaseous cosubstrate in bioremediation of hydrocarbon-polluted soil.
The stimulation of the microbial population by a more bioavailable supplementary carbon source and by a surfactant pretreatment was studied in petroleum hydrocarbon-polluted soils bioremediation. Two types of soils were used, Soil A which had been recently polluted and the aged Soil B. They contained 52.4 and 50.4 g of total petroleum hydrocarbons per kg of dry soil, respectively. The effect of...
متن کاملEffect of a nonionic surfactant on biodegradation of slowly desorbing PAHs in contaminated soils.
The influence of the nonionic surfactant Brij 35 on biodegradation of slowly desorbing polycyclic aromatic hydrocarbons (PAHs) was determined in contaminated soils. We employed a soil originated from a creosote-polluted site, and a manufactured gas plant soil that had been treated by bioremediation. The two soils differed in their total content in five indicator 3-, 4-, and 5-ring PAHs (2923 mg...
