Several nitrogen fixing consortia (NFC) were isolated from kerosene contaminated soil, where Phaseolus vulgaris plants were being cultivated. The capability of these consortia for kerosene hydrocarbons removal was investigated and demonstrated. The NFC cultivated under aerobic conditions, and kerosene as sole carbon source, effected a maximum of 75% of reduction of the total kerosene hydrocarbons. Also, from experiments conducted to evaluate their atmospheric nitrogen fixing capability, all consortia showed nitrogenase activity: from 4 to 183 nmol N2/3E09 bacteria.day. To our knowledge, this is the first report that shows a group of bacteria with the dual characteristic of fixing atmospheric nitrogen and capability to use kerosene hydrocarbons as a sole carbon source. Application of these microorganisms to soil bioremediation processes is discussed.

Used Lubricating Oil

Soil and surface water contamination by used lubricating oil is a common occurrence in most developing countries. This has been shown to have harmful effects on the environment and human beings at large. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 15% (w/w) used lubricating oil and amended with 10% brewery spent grain (BSG), banana skin (BS), and spent mushroom compost (SMC) was studied for a period of 84 days, under laboratory condition. At the end of 84 days, the highest percentage of oil biodegradation (92%) was recorded in soil contaminated with 5% used lubricating oil and amended with BSG, while only 55% of oil biodegradation was recorded in soil contaminated with 15% used lubricating oil and amended with BSG. Results of first-order kinetic model to determine the rate of biodegradation of used lubricating oil revealed that soil amended with BSG recorded the highest rate of oil biodegradation (0.4361 day−1) in 5% oil pollution, while BS amended soil recorded the highest rate of oil biodegradation (0.0556 day−1) in 15% oil pollution. The results of this study demonstrated the potential of BSG as a good substrate for enhanced remediation of hydrocarbon contaminated soil at low pollution concentration.

As anthropogenic activities rise over the world, representing an environmental threat, soil contamination and treatment of polluted areas have become a worldwide concern. Bioremediation is a sustainable technique that could be a cost-effective mitigating solution for heavy metal-polluted soil regeneration. Due to the difficulties in determining the optimum bioremediation methodology for each type of pollutant and the lack of literature on soil bioremediation, we reviewed the main in-situ type, their current properties, applications, and techniques, plants, and microbe’s efficiency for treatment of contaminated soil. In this review, we describe the deeper knowledge of the in-situ types of bioremediation and their different pollutant accumulation mechanisms.

this study intends to compare through the experiment research of potassium permanganate, Fenton reagent, sodium persulfate, hydrogen peroxide, four kinds of commonly used oxidant chlorobenzene in contaminated soil, the removal effect of O-O-dichlorobenzene;, selected a typical ground soil bioremediation is the best antioxidant effect. Research under the condition of different on the dose, 4 kinds of oxidants to chlorobenzene and O-O-dichlorobenzene; removal effect. Combined pollution ground soil properties screen of chlorobenzene in contaminated soil, the highest removal rate of dichlorobenzene oxidant and best delivery dosage, to apply typical ground soil bioremediation, the results show that the effect is the best Kmno4.
