In situ bioremediation of oily sludge-contaminated soil by biostimulation of indigenous microbes through adding manure was conducted at the Shengli oilfield in northern China. After bioremediation for 360 days, total petroleum hydrocarbon (TPH) content was reduced by 58.2% in the treated plots compared with only 15.6% in the control plot. Moreover, bioremediation significantly improved the phys...

In situ bioremediation is a groundwater and soil remediation technology that makes use of indigenous or introduced microorganisms to degrade contaminants in the subsurface. One factor affecting the feasibility of in situ bioremediation is the availability of the contaminant to the microorganisms. It is typically assumed that the contaminant is only available for biodegradation in the aqueous ph...

The advantages in using catalytic hydrophobic membranes in bioreactors operating under non-isothermal conditions, process of thermodialysis, for remediation of aqueous systems polluted by Endocrine Disruptors are discussed and illustrated. In presence of a transmembrane temperature gradient the enzyme activity increases along the yield of the bioremediation process. The theoretical bases accoun...

Nitrate enhanced bioremediation solubility of oxygen. Nitrate is more soluble than oxygen and is less expensive. The significance of the nitrate bioremediation at Traverse City is that the concentration of nitrate used in the bioremediation was below Federal drinking water standards. that when nitrate and nutrients were added, they could be evenly distributed In order to determine the effects o...

Wastewater is the remainder of an activity released in liquid form. product feared to have negative influence on environmental balance; therefore, it necessary measure quality standards wastewater as a reference disposal and treatment. Bioremediation environmentally friendly technology utilizing microorganisms agents process cleaning or restoring conditions. The use microorganism services can r...

Nitrobenzene is highly toxic liquid aromatic compound which is readily absorbed through the skin. Although nitrobenzene is not currently known to be a carcinogen, prolonged exposure may cause serious damage to the central nervous system, impair vision, cause liver or kidney damage, anaemia and lung irritation. Natural attenuation, biostimulation and bioaugmentation of nitrobenzene contaminated ...

Rapid detection and enumeration of target microorganisms is considered as a powerful tool for monitoring bioremediation process that typically involves cleaning up polluted environments with functional microbes. A novel colorimetric assay is presented based on immunomagnetic capture and bacterial intrinsic peroxidase activity for rapidly detecting Shewanella oneidensis, an important model organ...

Polycyclic aromatic hydrocarbons (PAHs) are major pollutants globally and due to their carcinogenic and mutagenic properties their clean-up is paramount. Bioremediation or using PAH degrading microorganisms (mainly bacteria) to degrade the pollutants represents cheap, effective methods. These PAH degraders harbor functional genes which help microorganisms use PAHs as source of food and energy. ...
