“…However, high degradation of the latter would have been obtained in some conditions. In the bioremediation of an aged PAH-contaminated soil by a microbial consortium, Li et al (2009) observed that the biodegradation of 5e6 rings PAHs was significantly higher than that of 2e4 rings PAHs. In our study the degradation of 3-ring PAHs was less than that of 4-or 5-ring PAHs, perhaps due to the bacterial consortium being enriched from a soil containing more than 90% of HMW-PAHs, and it had a greater capability to degrade HMW-PAHs.…”

“…Alisi et al (2009), successfully obtained complete degradation of diesel oil and phenanthrene; a reduction of 60% of isoprenoids; and an overall reduction of about 75% of the total hydrocarbons in 42 days, using a microbial formula made with selected native strains (Alisi et al 2009). Similarly, Li et al (2009) affirmed that indigenous microbes could degrade PAH in aged contaminated soil. Albeit, adding microbial consortia (five fungi: Phanerochaete chrysosporium, Cuuninghamella sp., Alternaria alternate (Fr.)…”

Bioaugmentation and biostimulation strategies to improve the effectiveness of bioremediation processes

Bioremediation, involving bioaugmentation and/or biostimulation, being an economical and eco-friendly approach, has emerged as the most advantageous soil and water clean-up technique for contaminated sites containing heavy metals and/or organic pollutants. Addition of pre-grown microbial cultures to enhance the degradation of unwanted compounds (bioaugmentation) and/or injection of nutrients and other supplementary components to the native microbial population to induce propagation at a hastened rate (biostimulation), are the most common approaches for in situ bioremediation of accidental spills and chronically contaminated sites worldwide. However, many factors like strain selection, microbial ecology, type of contaminant, environmental constraints, as well as procedures of culture introduction, may lead to their failure. These drawbacks, along with fragmented literature, have opened a gap between laboratory trials and on-field application. The present review discusses the effectiveness as well as the limitations of bioaugmentation and biostimulation processes. A summary of experimental studies both in confined systems under controlled conditions and of real case studies in the field is presented. A comparative account between the two techniques and also the current scenario worldwide for in situ biotreatment using bioaugmentation and biostimulation, are addressed.

“…The ability of the native soil microbes to degrade PAHs in a long-term polluted soil was reported by Li et al ( 2009b ). They also found that after supplementing a microbial consortium comprising three bacteria belonging to the genera Zoogloea , Flavobacterium and Bacillus , and fi ve different fungi, Aspergillus niger , Penicillium chrysogenum , Alternaria alternata , Phanerochaete chrysosporium and Cuuninghamella sp., the degradation rate of PAHs signifi cantly increased to 41.3 %.…”

Though several in-situ treatment methods exist to remediate polluted sites, selecting an appropriate site-specific remediation technology is challenging and is critical for successful clean up of polluted sites. Hence, a comprehensive overview of all the available remediation technologies to date is necessary to choose the right technology for an anticipated pollutant. This review has critically evaluated the (i) technological profile of existing in-situ remediation approaches for priority and emerging pollutants, (ii) recent innovative technologies for on-site pollutant remediation, and (iii) current challenges as well as future prospects for developing innovative approaches to enhance the efficacy of remediation at contaminated sites.
