“…Increases in SOM, Fe, Zn, and Mn in the disturbed sites suggest that soil redox conditions improved towards the end of the study. Overall, increased organic compounds in soil substrates from Cells and CSTUs may alleviate the amount of soil contamination due to hydrocarbons, as was found by Helmy et al (2015), who added glucose in such contaminated soils and recorded increased activity in oil-degrading bacteria. An increase of 0.3 to 0.9 pH units in all disturbed sites two years after planting could be considered another indicator of the beneficial effect of planted trees on these soils.…”

“…The variation of the microbial populations often indicates the change of the soil environment. Environmental pollution may cause a transformation in microbial community composition and activity [ 1 , 2 ]. Moreover, there is a dependent relation between microbial diversity and soil contamination [ 1 , 3 ].…”

Microorganisms are sensitive indicators of edaphic environmental variation. The Illumina MiSeq sequencing technology was used to analyze soil bacterial community diversity around an aging oil sludge in the Yellow River Delta. The alpha diversity index of soil bacterial community results (Ace, Chao, Shannon, and Simpson) determined that bacterial community diversity sampling within the scope of a 20 cm radius from the center of an aging oil sludge spot showed the most abundant diversity. The level of diversity distributed symmetrically with radial direction from the center of the aging oil sludge spot. Over the distance of 100 m from the center, bacterial community diversity tends to be monotonous, with small differences especially in the horizontal direction underground. The alpha-diversity indicators also showed that the bacterial diversity of samples were close under the aging oil sludge. In addition, the aging oil sludge inhibited the growth of bacteria compared with the referenced unpolluted soil sample and also increased the diversities of soil bacteria. At the phylum level, the Proteobacteria, Chloroflexi, and Actinobacteria existing in the aging oil sludge-contaminated wetland soil constituted a larger proportion of the community, while the proportion of Firmicute was relatively less. On the contrary, Firmicute showed the highest content of 63.8% in the referenced soil. Under the genus level and family level, the corresponding strains that resisted the aging oil sludge were selected. According to the bacterial diversity analysis, the basic structure of the bacterial community which could be used for remediation of aging oil sludge-contaminated soil was also developed.

“…The decrease of TPH was caused by two factors: bacteria in bioremediation process and the biosurfactant role. The role of Unidentified Mixed Culture bacteria or Petrofilic bacteria strongly biodegraded the hydrocarbon oil in slurry [12]. Moreover, the percentages of organic compound contained in solid (see Fig.…”

Abstract-Biosurfactant is potentially used to enhance oil recovery from oil sludge. The exopolysaccharide-formed biosurfactant is produced from Azotobacter sp. using 2 w/v% glucose sources. The oil sludge taken from company X and biosurfactant is agitated under the speed of 150 rpm and temperature of 20-25°C. The ratios of oil sludge and biosurfactant were varied by 1:1, 2:1 and 3:1. After 7 h agitation, the mixture was stood alone for 12 hours to obtain the 3 separated phases among oil (top), water (middle) and solid (bottom). The role of biosurfactant as surface tension reducer successfully separated among oil, water, solid from the oil sludge. The amounts of oil recovered from oil sludge are 55.95%, 51.76% and 25.57% for ratio 3:1, ratio 2:1, and ratio 1:1, respectively. Further, the slurry phase bioremediation method under 120 rpm of impeller velocity was applied to treat the bottom formation (slurry) from previous process. Both 5 w/v% Petrofilic bacteria (Unidentified Mix Culture) as a degrader agent and 5 w/v% fertilizer as nutrient were added in the first day of bioremediation process. Under controlled 10-40% solid concentration, 5.5-9.5 pH, 20-40°C (mesofilic condition), the total petroleum hydrocarbon (TPH) was successfully decreased until 6.83%, 3.48%, and 2.11% for slurry of ratio 1:1, ratio 2:1, and ratio 3:1 in 35 days.Index Terms-Azotobacter sp., biosurfactant, oil recovery, slurry Phase bioremediation.
