it is known that native oil-degrading microorganisms are ubiquitous. they can be isolated from contaminated soils. in this study, biodegradation experiments were carried out to evaluate the efficiency of pollutant removal by adding the selected microorganisms. five mixed cultures and 3 single bacteria strains, pseudomonas sp., arthrobacter sp. and mycobacterium sp. were isolated from hydrocarbo...

a study was conducted in 2010 to investigate the effects of crude oil contaminated soil on biomass accumulation injatropha curcas seedlings in asaba, delta state, nigeria. oil levels used were 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0% w/w. the trial was arranged in a randomized complete block design with four replications and monitored for 12 weeks after transplanting. results showed that contamination...

the removal of disulfide oil (dso) from contaminated soil was studied by the bioremediation method and the influence of electrokinetic on the bioremediation process was investigated. the bacillus subtilis strain was used in the bioremediation process. the effects of humidity, time and dso concentration in soil was studied. the experimental results for the bioremediation of dso show, the removal...

bone matrix gelatin (bmg) has been used for bone induction intramuscularly and subcutaneously by many investigators since 1965. more recently, some of the researchers have used bmg particles for bone repair and reported various results. in present study for evaluation of bone induction and new bone formation in parital defects, bmg particles were used in five groups of rats. the bmg was prepare...

Pilot plant studies were carried out to evaluate the feasibility of remediation of coal tarcontaminated soil and oil-contaminated gravel by incineration with environmentally acceptable performance. In addition to adequate decontamination and emission control, effort was devoted to treating the special feedstocks with difficult handling properties by use of conventional combustion and feeding sy...

Studies have shown a link between Q-fever positive farms (QFPFs) and community cases of human Q-fever. Our study is the first to investigate the potential role of contaminated land-applied manure in human Q-fever, based on a large set of nationwide notification and farm management data. Time between manure application and disease onset in geographically linked notified human cases coincided wit...
