“…Such products will require a high level of robustness to be exposed to diverse environments. However, enriched cultures of selected indigenous microbes could produce a more appropriate and cost-effective product for local conditions than commercial bioremediation products (Mohammed et al 2007). Some examples of commercial bioremediation agents/products and their formulations are shown in Table 2.…”

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.

“…During in situ biodegradation a conflict between the applied consortia members and the autochthonic microflora might occur. Therefore, apart from environmental factors (Allard and Neilson 1997), the possible interactions between the microorganisms should also be considered (Miralles et al 2007, Mohammed et al 2007. Cell leaching from the remediation site is another major problem.…”

Recent biodegradation researches are focused on improving the deterioration efficiency and maintaining the stability of microbial activity during the process. Immobilizing bacterial cells by using the adhesive method is a simple way to achieve both objectives. The purpose of this study was to evaluate how the immobilization of bacterial cells by the biofilm forming method influences the biodegradation efficiency of two different bacterial consortia-low diesel oil degraders (base deterioration efficiency \ 40%) and high phenol degraders (base deterioration efficiency [ 90%). The degradation tests were carried out on four different carriers (expanded clay pellets, polypropylene, polyvinyl chloride rings and paperboard). The obtained results show that biofilms may considerably increase the efficiency of low degraders. The best diesel oil deterioration (80%) was achieved when paperboard was used as a carrier. However, the immobilization of high degraders did not significantly influence their base biodegradation potential. A 6% increase was noted only for the expanded clay pellets.

“…There have been several studies published describing the biodegradation of petroleum-derived hydrocarbons [3][4][5][6][7][8]. According to Chapelle [7], microbiological populations are generally able to degrade hydrocarbons under both aerobic and anaerobic conditions in contaminated underground aquifers.…”
