... growth and MIC. In this work, a commercial cellulose-based polymer (carboxymethyl cellulose sodium) at 3,000 ppm (w/w) was tested in 125 ml anaerobic vials to see whether it could be utilized by an oilfield biofilm consortium containing SRB and biodegradation microbes during a 30-day incubation period...

...Abstract Continuous biodegradation of air pollutants i.e., volatile organic compounds (VOC), which are released to the atmosphere during many industrial operations, is one of the fastest-growing areas of bio-technology. Substantive bacterial growth, immobilization and VOC-degradation reaction...

Biodegradation Bioremediation hydrocarbon soil metal working concrete cleaning corrosion protection INTRODUCTION Petroleum oil contamination is becoming increasingly common as our use of hydrocarbons...

... and the ecotoxicity profiles for aquatic invertebrates, fish, and algae are presented. Environmental toxicity may be reduced or eliminated following degradation of the biocide active ingredients under environment conditions. Key elements of the environmental fate profile include biodegradability, bioaccumulation, end...

... criteria may be adhered to while developing an inhibitor for Indian oil and gas industry: Laboratory tests may not be adequate always. The process of biodegradation itself can cause some damage if the products of biodegradation are toxic than the original product itself. It may also lead to oxygen...

... inhibitors biodegradation bioaccumulation toxicity risk analysis risk-management INTRODUCTION Corrosion inhibitors continue to play a key role in controlling internal corrosion associated with oil and gas production and transportation. Future oil and gas production will occur in more remote areas...

.... We initiated an investigation on biodegradability of phthalic acid and DMPE’s. Enrichment cultures of bacteria obtained from activated sludge and mangrove can fully mineralize this group of compounds within a short period of time. However, it was also found that single species of bacteria were...

... toxicity results determined for the discharge locations and applied to CBR modeling, reviewed here, are based on acute toxicity tests (ASTM Designation: E 1192-88) applied to mysid shrimp, Mysidopsis bahia and the silverside, Menidi beryllina using samples of fresh and the biodegraded...

... mass spectrometry (GC-MS). Although a significant microbial growth was confirmed, no reduction in the corrosion inhibition efficacy was found. Pseudomonas fluorescens sulfate-reducing bacteria film-forming corrosion inhibitors biodegradation gas chromatography mass spectrometry (GC-MS...

... extensive testing. Isothiazolone biocides are broad spectrum antimicrobials which are used in a variety of industrial water treatment applications. In aquatic environments, these compounds rapidly biodegrade with half-lives significantly less than 24 hours. Metabolism involves cleavage of the isothiazolone...
