Biodegradation of phenol in refinery wastewater by pure cultures of Pseudomonas aeruginosa NCIB 950 and Pseudomonas fluorescence NCIB 3756
The potential of microorganisms to catabolise and metabolise xenobiotic compounds has been recognised as a potentially effective means of toxic and hazardous wastes disposal. Phenol and its derivatives have long been recognised as some of the most persistent chemicals in petroleum refinery wastewaters, with high toxicity even at low concentrations. Biodegradation of these compounds has been ...

In-Situ Petroleum Bioremediation Rates With Petrox
Recent data from field applications of Petrox bioremediation show degradation rates of 100 to 500 micrograms per liter (ug/ml) per day. These degradation rates are for total petroleum hydrocarbons or total BTEX, depending on the site monitoring requirements. Achieving high degradation rates requires high initial concentrations. Initial concentrations of 1,000 to 10,000 ug/l were used to develop ...

Choosing the Right Product for Ex Situ Petroleum Bioremediation
Selecting the right product for ex situ petroleum bioremediation comes down to usability factors. Both Petrox and Custom Blend products quickly degrade petreleum in soil. The average petrolem removal rate for Petrox bioremediation is 68 mg/kg/day. The average removal rate for Custom Blend is 1,315 mg/kg/day. The actual field results can vary depending of the effective distribution if microbes in ...

Bioremediation of petroleum hydrocarbons through landfarming: Are simplicity and cost-effectiveness the only advantages?
The biological removal of petroleum products using landfarming has been applied commercially in large scale with relative success. The technology has been widely used due to its simplicity and cost-effectiveness. However, together with these advantages, there are physical, chemical and biological aspects of the technology that can hamper the remediation process. The dominant pollutant removal ...

Integrated 3D physical-numerical modelling for simulating bioremediation of petroleum contamination in heterogeneous subsurface environment
This study presents physical-numerical modelling of petroleum contaminant transport and enhanced in situ bioremediation in heterogeneous subsurface environment. The approach is based on development of a three-dimensional multi-layered physical model coupled with a three-dimensional multiphase multi-component numerical model. An experimental scheme was designed to conduct 40-day benzene transport, ...

Bioremediation of petroleum contaminated Soils in Brazil Using AgroRemed
At Atuba at the corporate site of COPEL, a state owned utility company, soil was heavily contaminated with transformer oil due to a long history of contamination since 1964 probably due to unsafe practices of storage and cleanup. The level of contamination measures as TPH in soil was as high as 766,695 ppm and much of the contamination was at a depth of 1 meter. The site is located on a hill and ...

Biodegradation of total petroleum hydrocarbon (TPH) in Jordanian petroleum sludge
Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environment-friendly treatment for oil-contaminated sites. In this study, the results are presented concerning a laboratory screening of several natural bacterial consortia and laboratory tests to establish the performance in degradation of hydrocarbons contained in oily ...

In Situ TPH Bioremediation with Petrox
With Petrox microbes, in situ TPH bioremediation reduced the concentration of petroleum in soil at a former gas station from 9,500 mg/kg to 52 mg/kg. The impacted soil was at more than 20 feet deep. Injection of calcium peroxide provided the oxygen needed for metabolism of the petroleum by Petrox microbes. The post treatment sampling was 90 days after the bioaugmentation, so that even though ...
