A Review On Bioremediation Of Petroleum Hydrocarbon Contaminants In Soil

Abstract

This review article illustrates the pros and cons of using bioremediation process for the remediation of petroleum contaminants in soil. Bioremediation along with other processes have been used to remediate petroleum hydrocarbon contaminants in soil in past. The major constituents of most crude oils are biodegradable, so bioremediation has proven to be cheap and efficient than others techniques. Different organisms are employed using various technique of bioremediation according to hydrocarbon present in the contaminated soil. Bioremediation is simpler, less labor intensive and public attitude toward bioremediation are generally favorable, the lack of knowledge about microorganisms and their natural role in the environment could affect the acceptability of their use. However, bioremediation can be considered one of the best technologies to deal with petroleum product contaminated soil.

Biotechnological advances in bioremediation of heavy metals contaminated ecosystems: an overview with special reference to phytoremediation

“…Temperature affects biochemical reaction rates and the rates are double for each 10°C rise in temperature; and (9) Oxygen-it is mainly used for the initial breakdown of the hydrocarbon in the contaminated sites. Also, the amount of available oxygen will determine whether the bioremediation is carried out under aerobic or anaerobic condition (Thapa et al 2012). It is the fact that although relevant knowledge has been gained in the field of bioremediation-through intensive laboratory researchthe exploitation of these innovations has not been fully realized (Ramos et al 2011).…”

Evaluation of Phytoremediation and Bioremediation for Sandy Soil Contaminated with Petroleum Hydrocarbons

“…In Treatment 1 (bacteria), the reduction of TPH was suggested to be due to the fact that bacteria take the hydrocarbon contaminants as a supplement for population. Bacteria take the hydrocarbon contaminants as source of carbon for new cells constituents and bacteria release enzymes in the soil, which have the ability to catalyze the oxidation of hydrocarbons contaminants [2]- [16].…”

Bioremediation of Diesel Fuel by Fungal Consortium Using Statistical Experimental Designs

“…method that is harmless and ecofriendly [4,7,8]. The principle of bioremediation or the microbial degradation process is about using microbes to destroy hazardous contaminants and convert them to harmless products [2,[9][10][11][12].…”
