today oil removal from contaminated soil by new methods such as bioremediation is necessary.  in this paper, the effect of chemical fertilizers and aeration on bioremediation of oil-contaminated soil has been investigated. also the control group, (bioremediation of petroleum hydrocarbons in contaminated soil without treatment by chemical fertilizers and aeration treatment was examined. the cond...

Efficient pretreatment of lignocellulosic biomass is needed to reduce associated energy costs. Lignin-degrading bacteria ( Comamonas testosteroni, Agrobacterium sp. , Lysinibacillus sphaericus, and Paenibacillus sp.) were tested as potential pre-treatment methods for oil palm empty fruit bunches (OPEFB) enhance its methane yield during anaerobic digestion (AD). The lignocellulose fractions anal...

Bioremediation of diesel oil in soil can occur by natural attenuation, or treated by biostimulation or bioaugmentation. In this study we evaluated all three technologies on the degradation of total petroleum hydrocarbons (TPH) in soil. In addition, the number of diesel-degrading microorganisms present and microbial activity as indexed by the dehydrogenase assay were monitored. Soils contaminate...

The main purpose of this research is studying the possibility of bioremediation of polycyclic aromatic hydrocarbons (PAHs) contaminated soils in Iran’s tar refinery area located in Isfahan. For many years a great quantity of tar produced by neighboring metallurgical plant has been stored in lagoons as natural reservoirs, causing the contamination of soil in this area. Microorganisms capable of ...
