“…The influence of microbial cultures and inorganic and organic amendments on the degradation of various soil contaminants has been examined in both surface and sub-surface soil environments (Smindoll et al 1988;Cho et al 1997;Juhasz 2005;Singh et al 2006). Abiotic factors such as soil texture, pH, temperature, moisture content, organic matter content and substrate availability should be carefully considered as part of the nutrient or microbial augmentation strategy in bioremediation processes (Thompson et al 2005).…”

“…In particular, nitrogen and/or phosphate sources are commonly added to stimulate biodegradation (Atagana 2006;Bogan et al 2001;Guerin 1999;Hwang and Cutright 2002;Negri et al 2004;Sabate et al 2006;Williams et al 1999). Other substrates, such as easily degraded carbon sources (van Herwijnen et al 2006), compost (Namkoong et al 2002;Scelza et al 2007), wood chips (Negri et al 2004), manure (Cho et al 1997), poultry litter (Williams et al 1999), and sewage (Namkoong et al 2002) have also been tested as biostimulants. Salicylate, an intermediate in the metabolism of some PAH, has been shown to induce PAH degradation in some bacteria (Chen and Aitken 1999;Kamath et al 2004;Tian et al 2003) and has also been used as a biostimulant to increase the abundance of naphthalene-degrading bacteria in soils (Colbert et al 1993;Ogunseitan et al 1991;Ogunseitan and Olson 1993;Powell 2006;van Herwijnen et al 2006).…”

Effects of enrichment with phthalate on polycyclic aromatic hydrocarbon biodegradation in contaminated soil

2007

The effect of enrichment with phthalate on the biodegradation of polycyclic aromatic hydrocarbons (PAH) was tested with bioreactor-treated and untreated contaminated soil from a former manufactured gas plant (MGP) site. Soil samples that had been treated in a bioreactor and enriched with phthalate mineralized (14)C-labeled phenanthrene and pyrene to a greater extent than unenriched samples over a 22.5-h incubation, but did not stimulate benzo[a]pyrene mineralization. In contrast to the positive effects on (14)C-labeled phenanthrene and pyrene, no significant differences were found in the extent of biodegradation of native PAH when untreated contaminated soil was incubated with and without phthalate amendment. Denaturing-gradient gel electrophoresis (DGGE) profiles of bacterial 16S rRNA genes from unenriched and phthalate-enriched soil samples were substantially different, and clonal sequences matched to prominent DGGE bands revealed that beta-Proteobacteria related to Ralstonia were most highly enriched by phthalate addition. Quantitative real-time PCR analyses confirmed that, of previously determined PAH-degraders in the bioreactor, only Ralstonia-type organisms increased in response to enrichment, accounting for 89% of the additional bacterial 16S rRNA genes resulting from phthalate enrichment. These findings indicate that phthalate amendment of this particular PAH-contaminated soil did not significantly enrich for organisms associated with high molecular weight PAH degradation or have any significant effect on overall degradation of native PAH in the soil.

“…The selected indigenous bacterial consortium has been shown to assist in bioremediation and has the advantage of being resistant to variations in natural environment (12,21). To effectively transfer the microorganisms to the contaminated site, a number of carrier materials, mostly agricultural by-products, are being used (8,23,34). The carrier materials transfer the microorganisms without affecting their population or capacity to degrade oily sludge.…”

A full-scale study evaluating an inoculum addition to stimulate in situ bioremediation of oily-sludgecontaminated soil was conducted at an oil refinery where the indigenous population of hydrocarbon-degrading bacteria in the soil was very low (10 3 to 10 4 CFU/g of soil). A feasibility study was conducted prior to the full-scale bioremediation study. In this feasibility study, out of six treatments, the application of a bacterial consortium and nutrients resulted in maximum biodegradation of total petroleum hydrocarbon (TPH) in 120 days. Therefore, this treatment was selected for the full-scale study. In the full-scale study, plots A and B were treated with a bacterial consortium and nutrients, which resulted in 92.0 and 89.7% removal of TPH, respectively, in 1 year, compared to 14.0% removal of TPH in the control plot C. In plot A, the alkane fraction of TPH was reduced by 94.2%, the aromatic fraction of TPH was reduced by 91.9%, and NSO (nitrogen-, sulfur-, and oxygen-containing compound) and asphaltene fractions of TPH were reduced by 85.2% in 1 year. Similarly, in plot B the degradation of alkane, aromatic, and NSO plus asphaltene fractions of TPH was 95.1, 94.8, and 63.5%, respectively, in 345 days. However, in plot C, removal of alkane (17.3%), aromatic (12.9%), and NSO plus asphaltene (5.8%) fractions was much less. The population of introduced Acinetobacter baumannii strains in plots A and B was stable even after 1 year. Physical and chemical properties of the soil at the bioremediation site improved significantly in 1 year.
