Enhanced remediation of sewage effluent by endophyte-assisted floating treatment wetlands. 2014) is submerged in the trajectory of polluted groundwater. Introduction Textile industries consume huge quantities of water and generate an enormous amount of impurities including dyes, detergents, additives, suspended solids, aldehydes, heavy metals, non-biodegradable matter, and insoluble substances [ [1], [2], [3], [4] ]. Altmetric Review Article. The aim of this review is to provide a comprehensive knowledge on the two major bioremediation techniques with regards to site of application, highlighting their principles, advantages, limitations and possible solutions. The high percentage of TPH reduction was attributed to synergistic interaction between bioaugmentation and biostimulation, thus demonstrating the flexibility of biopiles for bioremediation. Unlike bioventing that relies on enhancing microbial degradation process at the vadose zone by moderate air injection, soil vapour extraction (SVE) maximizes volatile organic compound volatilization via vapour extraction (Magalhes et al. The use of agar, agarose, alginate, gelatin, gellan gum and polyurethane as carrier materials will help solve some of the challenges associated with bioagumentation (Tyagi et al. In addition, bioreactor being an enclosed system, genetically modified microorganism (GEM) can be used for bioaugmentation after which the organism (GEM) can be destroyed before treated soils are returned to field for landfilling. (2008) reported that biosparging of benzene, toluene, ethylbenzene and xylene (BTEX)-contaminated aquifer plume resulted in a shift from anaerobic to aerobic conditions; this was evidenced by increased dissolved oxygen, redox potentials, nitrate, sulphate and total culturable heterotrophs with a corresponding decrease in dissolved ferrous iron, sulphide, methane and total anaerobes and methanogens. A review on phytoremediation of crude oil spills. Furthermore, given the nature of activities leading to crude oil pollution, it is likely that pollution of the environment with pollutants excluding hydrocarbons can easily be prevented and controlled. Thus far, several good definitions have been given to bioremediation, with particular emphasis on one of the processes (degradation).

Removal of ammonium-nitrogen from groundwater using a fully passive permeable reactive barrier with oxygen-releasing compound and clinoptilolite. Therefore, choosing appropriate bioremediation technique, which will effectively reduce pollutant concentrations to an innocuous state, is crucial for a successful bioremediation project. The components of this technique are: aeration, irrigation, nutrient and leachate collection systems, and a treatment bed. Decrease in long-term performance due to reduction in reactivity of the barrier, zero-valent iron (ZVI), loss of porosity and inability to apply the technique to site contaminated with some chlorinated hydrocarbons and recalcitrant compounds are amongst the major operational challenges associated with PRB technique. Investigations into the application of a combination of bioventing and biotrickling filter technologies for soil decontamination processesa transition regime between bioventing and soil vapour extraction. Nonetheless, low air injection rate resulted in a significant increase in biodegradation. Although bioaugmentation has proven effective, competition between endogenous and exogenous microbial populations, the risk of introducing pathogenic organisms into an environment, and the possibility that the inoculated microorganisms may not survive in the new environment make bioaugmentation a very skeptical approach. The over all decrease in BTEX reduction (>70%) further indicates that biosparging can be used to remediate BTEX contaminated ground water. This suggests that removal of HMWPAHs, which are of public health concern in polluted environment, could be more efficient if microbes with special degradative capabilities are incorporated while stimulating resident microbes with nutrients, rather than relying on a single approach alone.

Bioremediation is an attractive and successful cleaning technique to remove toxic waste from polluted environment. Notwithstanding, bacterial containment systems, in which any GEM escaping an environment will be killed by induction of controlled suicide systems will help gain public acceptance of using GEM to restore polluted environment. The Journal of Bioremediation & Biodegradation is an academic journal hosted by OMICS International a pioneer in open access publishingand is listed among the top 10 journals in bioremediation.

Meagher RB. Bioremediation can either be Some pollutants removed by bioreactor-based bioremediation. In addition, the plant should be resistant to diseases and pests (Lee 2013). When excavated polluted soil is treated on-site, it can be regarded as in situ; otherwise, it is ex situ as it has more in common with other ex situ bioremediation techniques. Altmetric Review Article. As polluted water flows through the barrier under its natural gradient, pollutants become trapped and undergo series of reactions resulting in clean water in the flow through (Thiruvenkatachari et al. Recently, Thijs et al. 2015). Further, engineering microorganisms with degradative pathway of a target compound using synthetic biology approach could improve bioremediation efficiency. It was observed that at two different air injection rates (81.504 and 407.52m3/d), no significant difference in contaminant (toluene) removal was observed at the end of the study period (200days).

On the other hand, organic pollutants (hydrocarbons and chlorinated compounds) are predominantly removed by degradation, rhizoremediation, stabilization and volatilization, with mineralization being possible when some plants such as willow and alfalfa are used (Meagher 2000; Kuiper et al. Further, it can be used to treat soil or water polluted with volatile organic compounds (VOCs) including benzene, toluene, ethylbenzene and xylenes (BTEX). (2008) reported >80% contaminant (diesel) removal by aeration using rototilling approach at remote Canadian Arctic location over a 3-year study period; this further demonstrates that in land farming technique, aeration plays crucial role in pollutant removal especially at cold regions. 2012a, b). Yang Y, Wang Y, Hristovski K, Westerhoff P. Simultaneous removal of nanosilver and fullerene in sequencing batch reactors for biological wastewater treatment. Firstly, due to bioreactor being ex situ technique, the volume of polluted soil or other substances to be treated may be too large, requiring more manpower, capital and safety measures for transporting pollutant to treatment site, therefore, making this particular technique cost ineffective (Philp and Atlas 2005). Bioremediation of Diesel Contaminated Marine Water by Bacteria: A Review and Bibliometric Analysis by Farah Eryssa Khalid 1, Zheng Syuen Lim 1, Suriana Sabri 2, Claudio Gomez-Fuentes 3,4, Azham Zulkharnain 5 and Siti Aqlima Ahmad 1,4,6,* 1 Fingerprinting hydrocarbons in a contaminated soil from an Italian natural reserve and assessment of the performance of a low-impact bioremediation approach. Incorporation of agro-industrial wastes as nutrient sources for putative biosurfactant producers during fermentation may increase biosurfactant yield. It thus follows that prior to application of intrinsic bioremediation, risk assessment needs to be carried out to ensure that remediation time is less than the time stipulated for pollutant to reach exposure point relative to the closest human and animal populations. Windrow treatment when compared to biopile treatment, showed higher rate of hydrocarbon removal; however, the higher efficiency of the windrow towards hydrocarbon removal was as a result of the soil type, which was reported to be more friable (Coulon et al. Land farming is amongst the simplest bioremediation techniques owing to its low cost and less equipment requirement for operation. Moreover, it was reported that intrinsic bioremediation does not result in adequate polyaromatic hydrocarbon (PAH) removal and corresponding reduction in polluted soil eco-toxicity (Garca-Delgado et al. Besaltatpour A, Hajabbasi M, Khoshgoftarmanesh A, Dorostkar V. Landfarming process effects on biochemical properties of petroleum-contaminated soils. However, high production cost and low scalability make large-scale application of biosurfactants to polluted site uneconomical. Phytoremediation of toxic elemental organic pollutants. Biostimulation involves the addition of nutrients or substrates to a polluted sample in order to stimulate the activities of autochthonous microbes. 2010). Developments in odour control and waste gas treatment biotechnology: a review. 2002). 2015). Biopile setup can easily be scaled up to a pilot system to achieve similar performance obtained during laboratory studies (Chemlal et al. This is due to possibility of engineering a designer biocatalyst (GEM, which can effectively degrade a target pollutant including recalcitrant compounds) by incorporating a novel and efficient metabolic pathways, widening the substrate range of existing pathways and increasing stability of catabolic activity (Paul et al. Nevertheless, horizontal gene transfer and uncontrolled multiplication of GEM in an environment limit the application of such a promising approach. A process called bioremediation can be used to turn abandoned mining sites into useful agricultural land. Lee JH. Mumford KA, Rayner JL, Snape I, Stevens GW.

Remediation of petroleum contaminated soils through composting and rhizosphere degradation. As one of ex situ bioremediation techniques, windrows rely on periodic turning of piled polluted soil to enhance bioremediation by increasing degradation activities of indigenous and/or transient hydrocarbonoclastic bacteria present in polluted soil. Ideally, these techniques ought to be less expensive compared to ex situ bioremediation techniques, due to no extra cost required for excavation processes; nonetheless, cost of design and on-site installation of some sophisticated equipment to improve microbial activities during bioremediation is of major concern. More so, Sun et al. Different plant species have been reported to have innate ability to remove organic and elemental pollutants from polluted sites (Table2). As with bioventing and soil vapour extraction (SVE), biosparing is similar in operation with a closely related technique known as in situ air sparging (IAS), which relies on high airflow rates to achieve pollutant volatilization, whereas biosparging promotes biodegradation. Obiri-Nyarko F, Grajales-Mesa SJ, Malina G. An overview of permeable reactive barriers for in situ sustainable groundwater remediation. The construction of a suitable land farming design with an impermeable liner minimizes leaching of pollutant into neighbouring areas during bioremediation operation (da Silva et al. Over all, land farming bioremediation technique is very simple to design and implement, requires low capital input and can be used to treat large volume of polluted soil with minimal environmental impact and energy requirement (Maila and Colete 2004). 2015). Folch A, Vilaplana M, Amado L, Vicent R, Caminal G. Fungal permeable reactive barrier to remediate groundwater in an artificial aquifer. 4.1. In addition, it was reported that biopile could be used to treat large volume of polluted soil in a limited space. ISSN: 2155-6199. Dreov Z, uovsk A, Hornk M, Pipka M, Gubiov M, Gubi J, Hostin S. Rhizofiltration potential of for cadmium and zinc removal from contaminated wastewater. Apparently, these combined techniques allowed polluted soil to maintain appropriate environmental conditions (pH, temperature, nutrients) needed for microbial growth, and resulted in surfactant biomass distribution across such polluted soil. World Journal of Microbiology & Biotechnology. Nevertheless, it was reported that tillage and irrigation without nutrient addition in a soil with appropriate biological activity increased heterotrophic and diesel-degrading bacterial counts thus enhancing the rate of bioremediation; dehydrogenase activity was also observed to be a good indicator of biostimulation treatment and could be used as a biological parameter in land farming technology (Silva-Castro et al. Yuan Journal of Elemental pollutants (toxic heavy metals and radionuclides) are mostly removed by extraction, transformation and sequesteration. In this review, bioremediation is defined as a process, which relies on biological mechanisms to reduce (degrade, detoxify, mineralize or transform) concentration of pollutants to an innocuous state. Nowadays, the world is facing the problem of different environmental pollution. A process called bioremediation can be used to turn abandoned mining sites into useful agricultural land.

Comparison of biopiled and windrowed soils contaminated with bunker-fuel in a full-scale trial. Yadav BK, Siebel MA, van Bruggen JJA. The absence of external force implies that the technique is less expensive compared to other in situ techniques. On the other hand, the excavation features of ex situ bioremediation tend to disrupt soil structure; as a result, polluted and surrounding sites alike experience more disturbances. However, longer remediation time, pollutant concentration, toxicity and bioavailability to plant, depth of plant roots and plant slow growth rate are likely to limit the application of phytoremediation (Kuiper et al. 2014); as a result, biodegradation and volatilization (weathering) are the two remediation mechanisms involved in pollutant removal. Fate and transport of petroleum hydrocarbons in engineered biopiles in polar regions. WebGenomics Approach to Bioremediation Provides insights into the various aspects of microbial genomics and biotechnology for environmental cleanup In recent years, the application of genomics to biodegradation and bioremediation research has led to a better understanding of the metabolic capabilities of microorganisms, their interactions with hazardous and toxic (2009) reported that humidified biopile had a very low final TPH concentration compared to heated and passive biopiles as a result of optimal moisture content, reduced leaching, minimal volatilization of less degradable contaminants. In: Atlas RM, Philp JC, editors. 2008; Volpe et al. However, unlike bioventing, air is injected at the saturated zone, which can cause upward movement of volatile organic compounds to the unsaturated zone to promote biodegradation. Sun G-D, Xu Y, Jin J-H, Zhong Z-P, Liu Y, Luo M, Liu Z-P. In most cases, it is regarded as ex situ bioremediation, while in some cases, it is regarded as in situ bioremediation technique. A clay permeable reactive barrier to remove Cs-137 from groundwater: column experiments.
