Polyacrylamide degradation and its implications
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21

The combined EGSB-ABR biosystem consisted of an EGSB reactor followed by an ABR ().The EGSB reactor was applied as the pretreatment of ABR. The EGSB reactor was made of plexiglass with 20 cm internal diameter and 210 cm height providing a working volume of 65 L, and a gas-liquid-solids separator was installed at the top of the column to separate the solids and biogas from the liquid phase.
Abstract In present study the biodegradation of partially hydrolyzed polyacrylamide (HPAM) by bacterial strains isolated from Omani oil fields was analyzed. HPAMs are extensively used in oil fields for enhanced oil recovery operations. The produced
Biodegradation of Polyacrylamide and Its Derivatives
Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation.
Polyacrylamide (PAM) used in sludge dewatering widely exists in high-solid anaerobic digestion. Degradation of polyacrylamide accompanied with accumulation of its toxic monomer is important to disposition of biogas residues. The potential of anaerobic digestion activity in microbial utilization of PAM was investigated in this study.
PubAg Search Results
The present study was designed to study the chemical constituents of the leaf essential oil of Curcuma caesia and its anti-oxidant, anti-inflammatory, antimicrobial and genotoxic efficacies. Chemical constituents of the oil were determined using Gas Chromatography/Mass Spectroscopy, showed 32 components; the major components were eucalyptol (16
Research Research interests. Endocrine Disruption: A major focus of my research interest is endocrine disruption, the study of chemicals that alter hormone function which can lead to adverse impacts on health. Our work with colleagues at Brunel University was some of the very first research to show that effluents from wastewater treatment works causes feminisation of male fish.

The Crude materials of basal discs and attachment integuments were estimated using standard measurement protocols. Total protein in the tissue was estimated by the Folin-Ciocalteu Phenol method of 65 Lowry et al. [].During spring, the adhesive basal discs or attachment integuments of the five species studied consisted contain 71 ± 0.61-72 ± 0.45% moisture, 22 ± 3.50-24 ± 0.21% protein, 1

Supramolecular Complexation of Carbohydrates for the
In this review, a comprehensive overview of advances in the supramolecular complexes of carbohydrates and poorly soluble drugs is presented. Through the complexation process, poorly soluble drugs could be efficiently delivered to their desired destinations. Carbohydrates, the most abundant biomolecules, have diverse physicochemical properties owing to their inherent three-dimensional
Fuel oxygenates such as methyl and ethyl tert- butyl ether (MTBE and ETBE, respectively) are degraded only by a limited number of bacterial strains. The aerobic pathway is generally thought to run via tert- butyl alcohol (TBA) and 2-hydroxyisobutyrate (2-HIBA), whereas further steps are unclear. We have now demonstrated for the newly isolated β-proteobacterial strains L108 and L10, as well as
- What is a water treatment system for home haemodialysis?
- Water treatment systems for home haemodialysis (Guidelines 7.1 – 7.5) Water of the appropriate quality used in the preparation of dialysis fluid is an essential requirement of haemodialysis and related therapies.
- Is hemodialysis a water-hungry treatment?
- Dialysis, particularly hemodialysis, is a water-hungry treatment that impacts the environment. The global annual water use of hemodialysis is approximately 265 million m 3 /yr. In this reference estimate, two-thirds of this water is represented by reverse osmosis reject water discharged into the drain.
- Is dialysis water suitable for modern haemodialysis therapies?
- There has been need for guidance on the detailed specification of water treatment systems as well as the building of haemodialysis units so that the dialysis water is fit for purpose for modern haemodialysis therapies (haemodiafiltration and high flux haemodialysis).
- Should a home haemodialysis patient use heat sanitization?
- The use of heat sanitization is preferable to eliminate the use of disinfecting chemicals by the home haemodialysis patient, reducing the associated exposure risk. Installation of an endotoxin retentive ultrafilter in either the dialysis water or dialysis fluid path to remove endotoxin and other microbial contaminants is desirable.
