“…While the uric acid-fed communities showed rapid growth, with cell numbers of up to 10 8 cells/mL and degradation of 70 % of total oil hydrocarbons, the cell numbers in the NPK-fertilised experiment remained 2 orders of magnitude lower and oil degradation was negligible. The data presented in our study is in concordance with a number of previous publications [27,42,43] which report enhanced microbial growth similar to what could be observed for the uric acid treatments. Microbial communities grew more rapidly and developed cell numbers 3 orders of magnitude higher than comparable treatments with soluble nitrogen sources [43].…”

“…It is therefore highly probable that marine oil degradation with uric acid as main nitrogen source requires a consortium of currently unknown uric acid-degrading microbes and highly adapted HCBs. This knowledge gap is very surprising as uric acid-based bioremediation approaches have been investigated in trials at different scales [28,27,42,43].…”

“…In bioaugmentation, the addition of oil-degrading bacteria boosts biodegradation rate, whereas in biostimulation, the growth of indigenous hydrocarbon degraders is stimulated by the addition of nutrients (mainly N and P) or other growth limiting nutrients (Nikolopoulou and Kalogerakis, 2010). Nikolopoulou et al, (2013) also mentioned that the success of oil spill bioremediation depends on the establishment and maintenance of physical, chemical and biological conditions that favor enhanced oil biodegradation rates in the marine environment. This result was incoherent with previous work (Nikolopolou et al, 2013;Ueno et al, 2007;Stallwood , 2005).…”

To investigate a suitable biological remediation approaches for anticipating oil spills in Cilacap sandy beach (Indonesia), some alternative strategies using biostimulation and a combination of biostimulation-bioaugmentation have been evaluated in inter tidal near shore Cilacap, Indonesia. The purpose of the study was to compare the efficacy of biostimulation using slow release fertilizer (SRF) only, combination of biostimulation-single strain bioaugmentation, and combination of biostimulation-consortium bioaugmentation, to enhance oil degradation. The experiment was conducted using sediment polluted 100,000 ppm Arabian Light Crude Oil in a mesocosm system for 90 days. The parameters measured were oil depletion, bacterial growth and changes in environmental conditions. The results showed that the affectivity on oil depletion of biostimulation-bioaugmentation combination was observed faster and higher than biostimulation only. At the 16 th day application, the biostimulation with the added consortium and single strain treatment, increased oil depletion percentage by 2.2 and 1.6 times that of the control, respectively. For a longer period of treatment, both of combination treatments showed similar efficacy in degrading oil contamination in sandy beach. It is proposed that combination of biostimulation-bioaugmentation with the consortium is relatively better alternative for combating oil-pollution for a short period.

“…Leaks and accidental spills during the manipulation, transportation, and storage of petroleum products are frequent, therefore, petroleum hydrocarbon contamination is a global concern [2,3]. Petroleum hydrocarbons are highly persistent in the environment and represent a significant risk for human health, impacting the biodiversity and the ecosystems around the world [4,5].…”

Petroleum hydrocarbons are highly persistent in the environment and represent a significant risk for humans, biodiversity, and the ecosystems. Frequently, hydrocarbon-contaminated sites remain polluted for decades due to a lack of proper decontamination treatments. Although bioremediation techniques have gained attention for being environmentally friendly, cost-effective and applicable in situ, their application is still limited. Each polluted soil has particularities, therefore, the bioremediation approach for a contaminated site is unique. Bioremediation cost studies are usually based on hypothetical assumptions rather than technical or experimental data. The research aims of this study were to clean-up chronically hydrocarbon-polluted soils using aerobic and anaerobic bioremediation techniques and to carry out an economic evaluation of the most promising bioremediation treatments. The results showed that aerobic biostimulation with vermicompost and aerobic bioaugmentation plus air venting were the most effective treatments, degrading 78% and 73% of total petroleum hydrocarbons (TPH) in chronically hydrocarbonpolluted soils after six weeks, respectively. In contrast, no significant degradation of hydrocarbon was observed by anaerobic biostimulation treatments with lactate and acetate. An economic evaluation of the aerobic treatments were carried out. This analysis revealed that the cost of treating one cubic meter of soil by biostimulation is US$ 59, while bioaugmentation costs US$77. This study provides a clear structure of costs for both aerobic bioremediation approaches based on projections made from these lab-scale incubations. These values represent the first step towards a better understanding of the feasibility of such treatments at larger scales, which is crucial to move on industrial bioremediation of soils chronically polluted with petroleum hydrocarbons.
