the objective of the study was to determine the effect of the process of natural bioremediation, and bioremediation supported by zb-01 microbiological preparation on the occurrence of collembola and araneae in conditions of soil contaminated by petroleum-derived substances. the studies were conducted in 2010-2012, in the area of the experiment station of the university of agriculture, near krak...
آلودگی آب های دریایی با هیدروکربن های پلی آروماتیک (pahs) سبب آسیب های جبران ناپذیری در جانداران از جمله تخریب بافت جگر و سلول های قرمز خون و همچنین انواع سرطان ها می شوند. وجود این ترکیبات در محیط، ناشی از سوخت ناقص ترکیبات آلی ، تخلیه پس ماندهای ناشی از پالایشگاههای نفت و یا در اثر نشت نفت از تاسیسات ساحلی و کشتی های نفت کش می باشد. یافتن روش های مناسب برای کاهش این ترکیبات در محیط زیست دریا ...
Bioremediation is defined as the act of adding or improving the availability of materials (e.g., nutrients, microorganisms, or oxygen) to contaminated environments to cause an acceleration of natural biodegradative processes. The results of field experiments and trials following actual spill incidents have been reviewed to evaluate the feasibility of this approach as a treatment for oil contami...
Successful bioremediation of hydrocarbon contamination in terrestrial as well as aquatic ecosystems is generally limited by the low bioavailability of hydrophobic pollutants. Considerably higher mass transfer rates and hydrocarbon solubilities can be obtained at higher temperatures, but so far approaches to bioremediation at increased temperature have hardly been investigated. The biotechnologi...
Crude oil extraction, transportation and use provoke the contamination of countless ecosystems. Therefore, bioremediation through surfactants mobilization or biodegradation is an important subject, both economically and environmentally. Bioremediation research had a great boost with the recent advances in Metagenomics, as it enabled the sequencing of uncultured microorganisms providing new insi...
