“…This time‐difference likely occurred because contamination in the restinga sediments occurred in the subsurface, with a smaller influence of oxygen. Additionally, the nutrients released by Osmocote® could reach the deeply buried oil layer and promote bioremediation. However, in P2 columns it took longer to reach the contaminated layer because the fertilizer was added to the tops of the columns.…”

“…Therefore, bioremediation was effective in enhancing heterotrophic bacteria in the sediment‐contaminated layers of P1 and P2 compared with the control. In this way, the biostimulation of indigenous microorganisms and providing sufficient nutrients, and air may represent the best approach to cleaning‐up hydrocarbon‐contaminated soil . Thus, it is important to consider that the excessive nutrients over metabolic requirements result in higher bioremediation costs, and potential marine eutrophication impacts and the optimal dosage of the fertilizer used should be determined, as proposed by Xu et al .…”

Bioremediation in petroleum-contaminated sediments was investigated under laboratory conditions that simulated an oil pipeline coming from the most productive offshore oil basin in Brazil and crossing the restinga ecosystem. Two scenarios were tested in case of an oil leakage of the pipeline: a superficial contamination of the beach sediment from the pipeline´s submarine section (P1) and a subsurface contamination of the restinga sediment (P2) in the onshore buried pipeline section. The slow-release fertilizer (SRF) Osmocote® was used in both P1 and P2 to stimulate oil biodegradation by the indigenous microorganisms, and its effectiveness was tested. After a 92-day experiment, biostimulation with Osmocote® was efficient, but differences were observed in the biodegradation behavior of the hydrocarbon compounds analyzed. The n-alkanes were biodegraded to trace levels after 28 days in P1 and P2, whereas pristane and phytane were totally degraded between days 28 and 42 in P1 and four weeks later in P2. Natural attenuation also played an important role in removing the n-alkanes and the isoalkanes (pristane and phytane). This research is innovative in using a SRF to develop a clean-up solution for the sensitive restinga ecosystem after an oil contamination event, especially when considering a leakage of the buried pipeline.

“…Bioremediation is an environment-friendly and effective approach for cleaning and restoring both superficial (Gallego et al, 2007) and buried oil-contaminated beaches (Pontes et al, 2013). This technique uses hydrocarbon-degrading microorganisms such as fungi and bacteria to degrade oil contaminants into non-toxic and simpler inorganic compounds, mostly carbon dioxide and water, via oxidation under aerobic conditions (Kostka et al, 2011).…”

“…Biostimulation is the addition of nutrients or biosurfactants (Whang et al, 2008) to enhance microorganism growth, whereas bioaugmentation involves inoculating sediments with a pre-grown microbial culture to enhance bioremediation in a given environment (D'Annibale et al, 2006;Thompson et al, 2005). Compared with biostimulation, bioaugmentation favours faster oil degradation (Pontes et al, 2013). Both laboratory and field studies have shown that bioaugmentation can enhance the biodegradation rate of contaminant oil and hence reduce the adaptation time (Mishra et al, 2001;Mukherjee and Bordoloi, 2011;Szulc et al, 2014).…”

Monoaromatic pollutants such as benzene, toluene, ethylbenzene and mixture of xylenes are now considered as widespread contaminants of groundwater. In situ bioremediation under natural attenuation or enhanced remediation has been successfully used for removal of organic pollutants, including monoaromatic compounds, from groundwater. Results published indicate that in some sites, intrinsic bioremediation can reduce the monoaromatic compounds content of contaminated water to reach standard levels of potable water. However, engineering bioremediation is faster and more efficient. Also, studies have shown that enhanced anaerobic bioremediation can be applied for many BTEX contaminated groundwaters, as it is simple, applicable and economical. This paper reviews microbiology and metabolism of monoaromatic biodegradation and in situ bioremediation for BTEX removal from groundwater under aerobic and anaerobic conditions. It also discusses the factors affecting and limiting bioremediation processes and interactions between monoaromatic pollutants and other compounds during the remediation processes.
