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.

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.

Toxic Heavy Metal

The contamination of toxic heavy metal Cadmium (Cd) in soils will be endanger the human health because it ismore available comparing to another toxic heavy metals. One method of Cd-contaminated soil bioremediation isusing exopolysachharide-producing bacteria Azotobacter. Exopolysachharides (EPS) can mobilize Cd through theformation of complex Cd-EPS which sequentially can increase the availability of Cd for plants uptake. A laboratoryexperiment has been done to study the EPS production and the viability of six Azotobacter isolates in the liquidculture containing 0.01, 0.1, and 1 mM CdCl2. The bacteria were cultured in liquid medium with and without CdCl2 for72 hours at room temperature. The EPS production was determined by gravimetric method after precipitationusing acetone and centrifugation at 7000 rpm. The result was that all of Azotobacter isolates produce EPS in thepresence of CdCl2. In the culture with 1 mM CdCl2, the density of Azotobacter sp. isolate BS3, LK5, LKM6 increasedsignificantly, and that of isolate LH16 decreased. No significant effect of CdCl2 on the density of isolate BS2 andLH15. This research suggested that some Azotobacter isolates were relatively resistence to the Cd and could bedeveloped as biological agents in Cd-contaminated soil bioremediation.

Toxicological Effect

The oilfield soil was contaminated for years by large quantities of aged oil sludge generated in the petroleum industry. In this study, physicochemical properties, contents of main pollutants, and fungal diversity of the aged oil sludge-contaminated soil were analyzed. Results revealed that aged oil sludge significantly changed physical and chemical properties of the receiving soil and increased the contents of main pollutants (petroleum hydrocarbons and heavy metals) in soil. Meanwhile, the internal transcribed spacer (ITS) sequencing by Illumina Miseq platform at each taxonomic level demonstrated that the toxicological effect of oil pollutants obviously influenced the fungal diversity and community structure in soil. Moreover, it was found that the presence of three genera (Cephalotheca, Lecanicillium, and Septoriella) appeared in aged oil sludge-contaminated soil. And oil pollutants promoted the growth of certain genera in Ascomycota (70.83%) and Basidiomycota (10.78%), such as Venturia, Alternaria, and Piloderma. Nevertheless, the growth of Mortierella (9.16%), Emericella (6.02%), and Bjerkandera (0.00%) was intensively limited. This study would aid thorough understanding of microbial diversity in oil-contaminated soil and thus provide new point of view to soil bioremediation.
