With the development of the petroleum industry, oil pollution has become widespread. It is harmful to the digestive, immune, reproductive, and nervous systems of fishes, wild animals, and humans, causing severe threats to ecological safety and human health. Gordonia has increasingly attracted attention in the treatment of alkane pollution for its outstanding performance against hydrophobic refractory substances. However, the lack of knowledge about alkane uptake and degradation restricts the application of gordonia . In this paper, we studied the strain lys1-3 of Gordonia sihwaniensis isolated from coal chemical wastewater, which showed good alkane degradation performance by lys1-3. It is found that stimulated by an alkane, lys1-3 secreted biosurfactants, which emulsified large alkane particles to smaller particles. By active transport, unmodified alkane was transferred into cells and produced a large amount of acid, which was secreted out of the cells.

“…To increase their polyolefin-degrading activity, they were mixed with a fuel oil-degrading bacterium, Gordonia amicalis JC11 (previously Gordonia sp. JC11), which had been studied for oil spill remediation in the presence of biosurfactants ( Laorrattanasak et al, 2016 ). Marine bacteria were initially selected to avoid the salt stress due to the high conductivity of drill cuttings ( Table 4 ).…”

Drill cuttings from petroleum exploration and production sites can cause diverse environmental problems. Total petroleum hydrocarbons (TPHs) are a major pollutant from the use of polyolefin-based mud. As an alternative to incineration, this study investigated the application of surfactant-enhanced washing technology prior to bioremediation. The washing step was necessary because the initial TPH concentrations were quite high at approximately 15% (w/w). Washing agents were formulated by varying the concentration of lipopeptide biosurfactant (in foamate or cell-free broth), Dehydol LS7TH (fatty alcohol ethoxylate 7EO, oleochemical surfactant) and butanol (as a lipophilic linker) at different salinities. The most efficient formula produced a Winsor Type I microemulsion (oil-in-water microemulsion) with polyolefin and contained only 20% (v/v) foamate and 2% (v/v) Dehydol LS7TH in water. Due to the synergistic behavior between the anionic lipopeptides and non-ionic Dehydol LS7TH, the formula efficiently removed 92% of the TPHs from the drill cuttings when applied in a jar test. To reduce the cost, the concentrations of each surfactant should be reduced; thus, the formula was optimized by the simplex lattice mixture design. In addition, cell-free broth, at a pH of 10, containing 3.0 g/L lipopeptides was applied instead of foamate because it was easy to prepare. The optimized formula removed 81.2% of the TPHs and contained 72.0% cell-free broth and 1.4% Dehydol LS7TH in water. A 20-kg soil washing system was later tested where the petroleum removal efficiency decreased to 70.7% due to polyolefin redeposition during separation of the washing solution. The remaining TPHs (4.5%) in the washed drilled cuttings were further degraded by a mixture of Marinobacter

Objective: The aim of study is to obtain a strain which can effectively degrade oil. Methods: By enrichment, domestication and separation of culture from the sample which comes from Qianjiang Guanghua Oilfield, the pure culture (G-40) was selected from the medium supplemented with oil as the sole source of carbon. The G-40 was preliminarily identified and classified by morphological observation, physiological and biochemical determination and sequence analyses of 16S rDNA. Effects of temperature, pH, oil concentration, salt concentration, inoculation amount, N and P source on the degradation of the oil were studied by single factor test. Meanwhile, the effects of temperature, pH, oil concentration and salt concentration were optimized by orthogonal design. Result: G-40 was isolated and identified as Brevibacillus laterosporus. The orthogonal design showed that the degradation rate of oil could reach 20.81%, 24.34% and 31.15% at 10 d, 20 d and 40 d under the optimal conditions which was 35˚C, initial pH 7.3, oil concentration 0.6%, salt concentration 0.5%, inoculum amount 8%, the optimal N and P was (NH 4 ) 2 SO 4 and K 2 HPO 4 . Conclusion: This study provides microbial resources for bioremediation of petroleum contaminated soil.
