“…In the aspect of practicability for clean-up processes, degradation of a wide range of hydrocarbons is significant for bioremediation of oil contamination (Atlas and Atlas, 1991). For example, in a field-scale study, 13e23% total hydrocarbon content was degraded by oil degradation microorganisms in the oily sludge and soil after 56 days (Ouyang et al, 2005). In another study, the bacterial strains obtained from oil reservoirs were evaluated for petroleum degradation ability.…”

a b s t r a c tA bacterial strain, CN-3, was isolated from petroleum-contaminated sediment in Bohai Bay, China. Morphological, physiological and phylogenetic analyses indicated that the strain belonged to the genus Dietzia. It was capable of utilizing a wide range of alkanes (C 14 eC 31 ), aromatic compounds and crude oil as the sole carbon and energy sources. The bacterium showed high degradation rate (>80%) of the saturated hydrocarbons of crude oil in the pH range of 6e9. The degradation rate was hardly affected at a NaCl concentration up to 85 g L À1 , indicating that the strain can tolerate high salinities. The real-time quantitative Polymerase Chain Reaction (PCR) results showed that the CYP153 genes could be significantly induced by C 14 , C 15 , C 16 , C 26 and pristane, whereas the transcription level of alkB gene was increased moderately with C 14 , C 15 , C 16 , C 26 and pristane induction condition. A high degradation extent, wide substrate range and facile conditions enhanced the potential for this bacterial strain to be used in the bioremediation of crude oil pollution.

“…Crude oil is a complex mixture of compounds that can be classified into four main groups: saturated hydrocarbons, aromatic hydrocarbons, resins and asphaltenes (Alonso-Gutierrez et al, 2011). The search for methods to reduce petroleum pollution is becoming increasingly significant and necessary (Ouyang et al, 2005;Mbadinga et al, 2011).…”

“…Landfill has been widely used for sludge disposal in China (Ouyang et al, 2005) and sludge-composting technology has also been applied sometimes (Wang et al, 2010). It is estimated that approximately 65% of mechanical dewatered sewage sludge in China is disposed in landfill (Zhan et al, 2014).…”

“…The effectiveness of this method has been previously demonstrated in the biodegradation of oil sludge from different origins (Bengtsson et al 1998;Ward et al 2003), in which removal of 80-99 % of sludge over 60-120 days was achieved with total petroleum hydrocarbon (TPH) concentrations of 26,000-50,000 mg kg -1 . Other studies report the use of composting biopiles in removal of hydrocarbon from drilling mud and refinery oil sludge with TPH concentrations of 100,000-371,000 mg kg -1 and removal efficiencies of 31-53 % (Al-Daher et al 2001;Ouyang et al 2005;Marín et al 2006). The difficulty associated with the treatment of oily sludge containing hydrocarbons is that they comprise a mixture of compounds, which may be saturated, aromatic and heteroatom compounds containing sulphur, oxygen or nitrogen (Balba et al 1998).…”

“…The application of biological alternatives for the treatment oily sludge has been aimed at the removal of hydrocarbons (Ouyang et al 2005;Marín et al 2006). In most of these studies, no account has been taken of the effect of the presence of other pollutants on degradation, such as sulphur and compounds derived from secondary biological processes that can occur in parallel.…”

Oily sludge from gas processing facilities contains components that are major environmental pollutants. Biodegradation is an alternative treatment, but can be affected by other components of the sludge, such as sulphur compounds, so it is important to evaluate the effect of these on oil biodegradation in order to prevent negative impacts. This work studied the transformation of sulphur compounds in oily sludge biodegradation systems at the microcosm level. The predominant sulphur compounds in the original sludge were elemental sulphur and pyrite (9,776 and 28,705.4 mg kg -1 , respectively). In the biodegradability assays, hydrocarbon concentrations decreased from 312,705.6 to 186, 760.3 mg kg -1 after 15 days of treatment. After this time, hydrocarbon degrading activity stopped, corresponding with a decrease in hydrocarbon degrading bacteria. These changes were related to a reduction in pH that inhibits biodegradation. During the assay, sulphur compounds were gradually oxidized and transformed. The concentration of sulphate increased from 5,096 to 64,868.3 mg kg -1 after 30 days in the assay, although controls were unchanged. Therefore, it is important to determine changes to the main compounds of the waste in order to assess their impact.
