“…In addition, some species of Fungus including Aspergillus, Mucor, Fusarium, and Penicilium are also petroleum degradation microorganism. Gordonia is widely distributed in land, coastal, and ocean environments, and could degrade various environmental pollutants, including benzothiophene, dibenzothiophene, alkanes, polycyclic aromatic hydrocarbons, and so on [54,67]. Different types of oil-degrading microorganisms are shown in Table 1.…”

Due to the toxicity of petroleum compounds, the increasing accidents of marine oil spills/leakages have had a significant impact on our environment. Recently, different remedial techniques for the treatment of marine petroleum pollution have been proposed, such as bioremediation, controlled burning, skimming, and solidifying. (Hedlund and Staley in Int J Syst Evol Microbiol 51: [61][62][63][64][65][66] 2001). This review introduces an important remedial method for marine oil pollution treatment-bioremediation technique-which is considered as a reliable, efficient, cost-effective, and eco-friendly method. First, the necessity of bioremediation for marine oil pollution was discussed. Second, this paper discussed the species of oil-degrading microorganisms, degradation pathways and mechanisms, the degradation rate and reaction model, and the factors affecting the degradation. Last, several suggestions for the further research in the field of marine oil spill bioremediation were proposed.

“…Water content in crude oil was measured as described by Hammer et al [15]. Wax, resins, and asphaltenes contents in crude oil were determined according to literature [5]. Solidifying point was determined by a kryoscope (SYP 1022-I, Shanghai, China) and viscosity was determined at 30 ℃ by a rotational viscometer (DNJ-5S, Shanghai, China).…”

“…Afterwards, the organic phase was condensed at 40℃ until the dichloromethane was completely evaporated. The dried crude oil sediment was dissolved in 20 mL dichloromethane and dehydrated with 2 g anhydrous sodium sulfate [5]. 0.5 μL oil sample was injected in an Agilent GC-MS (7890A/5975C, USA) with a split ratio of 5:1.…”

“…MEOR makes use of microbial activities and metabolic byproducts to reduce the viscosity and increase the fluidity of crude oil [4]. On the one hand, microorganisms can reduce the oil viscosity by degrading the long-chain saturated hydrocarbons and some of the other heavy oil fractions [5]; On the other hand, microorganisms can produce non-toxic products such as biosurfactants to increase the oil sweep efficiency through changing the reservoirs' physicochemical characteristics [6].…”

“…So applying biotechnology to recover the heavy crude oil might be urgently needed in the future. Thereinto, genus Pseudomonas is known as a high-efficiency crude oil degrader [5,9]. Meanwhile, genus Pseudomonas is able to produce rhamnolipid, which may be useful in the MEOR process [10].…”

Enhanced transport of microbes in subsurface is a focus in bioaugmentation applications for remediation of groundwater. In this study, the effect of low‐concentration monorhamnolipid biosurfactant on transport of Pseudomonas aeruginosa ATCC 9027 in natural porous media (silica sand and a sandy soil) with or without hexadecane as the nonaqueous phase liquids (NAPLs) was studied with miscible‐displacement experiments using artificial groundwater as the background solution. Transport of two types of cells was investigated, glucose‐grown and hexadecane‐grown cells with lower and higher cell surface hydrophobicity (CSH), respectively. A clean‐bed colloid deposition model was used to calculate deposition rate coefficients (k) for quantitative assessment on the effect of the rhamnolipid on the transport. In the absence of NAPLs, significant cell retention was observed in the sand (81% and 82% for glucose‐grown and hexadecane‐grown cells, respectively). Addition of low‐concentration rhamnolipid enhanced cell transport, with 40 mg/L of rhamnolipid reducing retention to 50% and 60% for glucose‐grown and hexadecane‐grown cells, respectively. The k values for both glucose‐grown and hexadecane‐grown cells correlated linearly with rhamnolipid‐dependent CSH quantitatively measured using a bacterial‐adhesion‐to‐hydrocarbon method. Retention of cells by the soil was nearly complete (>99%). Forty milligrams per liter of rhamnolipid reduced the retention to 95%. The presence of NAPLs in the sand enhanced the retention of hexadecane‐grown cells with higher CSH. Transport of cells in the presence of NAPLs was enhanced by rhamnolipid at all concentrations tested, and the relative enhancement was greater than in the absence of NAPLs. This study shows the importance of hydrophobic interaction on bacterial transport in natural porous media and the potential of using low‐concentration rhamnolipid for facilitating cell transport in subsurface for bioaugmentation efforts.
