“…Bioaugmentation is a promising and low-cost bioremediation method in which an effective bacterial isolate (s) or microbial consortium capable of degrading xenobiotics is administered to contaminated sites (Gentry et al 2004). The number of petroleum-degrading microbial isolates available for bioaugmentation is increasing (Van Hamme et al 2003;Singer et al 2005).…”

“…However, the soil environment is very complicated and the degrading ability of exogenously added microorganisms tends to be affected by the physicochemical and biological features of the soil environment. Sometimes, the administration of petroleum-degrading microorganisms leads to a failure of bioaugmentation (Vogel 1996;Gentry et al 2004). The two bioremediation treatments can be performed ex situ and in situ.…”

SummaryTwo bacterial species (isolates N and O) were isolated from a paddy soil microcosm that had been artificially contaminated with diesel oil to which extrinsic Pseudomonas aeruginosa, strain WatG, had been added exogenously. One bacterial species (isolate J) was isolated from a similar soil microcosm that had been biostimulated with Luria-Bertani (LB) medium. Isolates N and O, which were tentatively identified as Stenotrophomonas sp. and Ochromonas sp., respectively, by sequencing of their 16 S rRNA genes had no ability to degrade diesel oil on their own in any liquid medium. When each strain was cocultivated with P. aeruginosa strain WatG in liquid mineral salts medium containing 1% diesel oil, isolate N enhanced the degradation of diesel oil by P. aeruginosa strain WatG, but isolate O inhibited it. In contrast, isolate J, which was tentatively identified as a Rhodococcus sp., degraded diesel oil contained not only in liquid LB and mineral salts media, but also in paddy soil microcosms supplemented with LB medium. The bioaugmentation capacity of isolate J in soil microcosms contaminated with diesel oil was much higher than that of P. aeruginosa strain WatG. The possibility of using isolate J for autochthonous bioaugmentation is discussed.

“…This technology can be defined as the biologically catalyzed treatment of organic contaminants and can be used in different methodologies such as bioaugmentation (BA) and biostimulation (BS) (Moliterni et al 2012). BA uses an inoculated microbiota that has special affinity for the target contaminant (Gentry et al 2004); BS, the most usual, aims the enhancement of the activity of the autochthonous microorganisms by adjustment of the operating conditions that affect the bioremediation process the most, namely pH and moisture content (Moliterni et al 2012). There are several works proving the success of these two methodologies, such as in the treatment using BS of a mazut-contaminated soil (Beskoski et al 2011) or a hydrocarbon-contaminated subsoil of a metalworking plant (Menendez-Vega et al 2007), and the degradation of chlorpyrifos in soil through plasmid-mediated bioaugmentation .…”

Soil vapor extraction (SVE) and bioremedia-tion (BR) are two of the most common soil remediation technologies. Their application is widespread; however, both present limitations, namely related to the efficien-cies of SVE on organic soils and to the remediation times of some BR processes. This work aimed to study the combination of these two technologies in order to verify the achievement of the legal clean-up goals in soil remediation projects involving seven different simulated soils separately contaminated with toluene and xylene. The remediations consisted of the application of SVE followed by biostimulation. The results show that the combination of these two technologies is effective and manages to achieve the clean-up goals imposed by the Spanish Legislation. Under the experimental conditions used in this work, SVE is sufficient for the remediation of soils, contaminated separately with toluene and xylene, with organic matter contents (OMC) below 4 %. In soils with higher OMC, the use of BR, as a complementary technology, and when the concentration of contaminant in the gas phase of the soil reaches values near 1 mg/L, allows the achievement of the clean-up goals. The OMC was a key parameter because it hindered SVE due to adsorption phenomena but en-hanced the BR process because it acted as a microor-ganism and nutrient source.

“…This may sometimes involved addition of genetically engineered microorganisms suited for biodegradation of the hydrocarbon contaminants into the contaminated soil. Bioaugmentation is a promising and low-cost bioremediation strategy in which an effective bacterial isolate(s) or microbial consortium capable of degrading xenobiotics is administered to contaminated sites (Gentry et al, 2004). Successful bioremediation of soil contaminated with hydrocarbon sources through bioaugmentation has been reported by various authors.…”

Sometimes, the administration of petroleum degrading microorganisms leads to a failure of bioaugmentation (Vogel 1996;Gentry et al, 2004). Bioaugmentation is not always an effective solution for remediation of contaminated soil because in some cases laboratory strains of microorganisms rarely grow and biodegrade xenobiotics compared to the indigenous microbes (Thieman and Palladino 2009).…”
