“…Biological techniques may also be environmentally friendlier by simulating natural processes [3]. A number of studies have been carried out on bioremediation of petroleum-contaminated soils [4,5] but there have been few studies on bioremediation of oily sludge [6], especially at the field scale.…”

a b s t r a c tField-scale bioremediation of oily sludge in prepared beds was studied at Shengli oilfield in northern China. The influence of manure, coarse sand, sawdust, a specialized microbial preparation and greenhouse conditions on the efficiency of removal of oil and grease was evaluated. After bioremediation for 230 d, oil and grease content fell by 32-42 g kg −1 dry sludge in treated plots, indicating removal of 27-46% compared with only 15% in the control plot. Addition of manure, coarse sand, sawdust and greenhouse conditions significantly (p < 0.05) increased the amount removed. Moreover, the physico-chemical properties of the sludge in all treated plots improved significantly after bioremediation. Microbial biomass in sludge and community-level physiological profiling examined using BIOLOG microplates was also studied. Total petroleum hydrocarbon degraders and polycyclic aromatic hydrocarbon degraders increased in all treated oily sludge. The activity of sludge microbial communities increased markedly in the treated plots compared with the control. Canonical correspondence analysis showed that differences in substrate utilization patterns were highly correlated (p < 0.05) with sludge hydrolyzable N and oil and grease content. The biological toxicity of the oily sludge was lower following bioremediation in most of the treated plots as evaluated using Photobacterium phosphoreum T3.

“…As far as soil microbial population is concerned, representative values for crude oil biodegradation could be verified when compared to the results from Jorgensen et al (2000). Total heterotrophic and hydrocarbon-degrading bacteria 8.2x10 7 CFU/g and 5.4x10 4 MPN/g, respectively, which could degrade n-alkanes from 50 to 90% of n-alkanes after 5 months.…”

“…Soil samples were contaminated with three rates of phenanthrene, e.g., 100, 500 and 1000 mg kg −1 and mixed with distilled water in solids concentration of 30% by weight (30% soil and 70% water). The consortium was revived in culture medium which consisted of Mineral Salt Medium (MSM) based on phenanthrene concentrations and ratio of C/N/P in the range of 100/10/2 in the soil samples [17,18] . Beside of samples, blanks were prepared as a control of abiotic remediation.…”
