Ethylene glycol and polyethylene glycol catabolism by a sewage bacterium.
Bioconsequences Section, Unilever Research Port Sunlight Laboratory, Port Sunlight, Wirral, Merseyside L62 4XN, U.K. Polyethylene glycols are an important group of polymers used in the manufacture of explosives, cosmetics and pharmaceuticals. In addition, the polyoxyethylene group is the hydrophilic head group of non-ionic surfactants such as the alcohol ethoxylates used in detergent formulatio...
متن کاملMonodisperse polyethylene glycol diacrylate hydrogel microsphere formation by oxygen-controlled photopolymerization in a microfluidic device.
PEG-based hydrogels have become widely used as drug delivery and tissue scaffolding materials. Common among PEG hydrogel-forming polymers are photopolymerizable acrylates such as polyethylene glycol diacrylate (PEGDA). Microfluidics and microfabrication technologies have recently enabled the miniaturization of PEGDA structures, thus enabling many possible applications for nano- and micro- struc...
متن کاملPurification and characterization of polyethylene glycol dehydrogenase involved in the bacterial metabolism of polyethylene glycol.
Polyethylene glycol (PEG) dehydrogenase in crude extracts of a PEG 20,000-utilizing mixed culture was purified 24 times by precipitation with ammonium sulfate, solubilization with laurylbetaine, and chromatography with diethylamino-ethyl-cellulose, hydroxylapatite, and Sephadex G-200. The purified enzyme was confirmed to be homogeneous by sodium dodecyl sulfate-polyacrylamide gel electrophoresi...
متن کاملOptimization and Evaluation of Polyethylene Glycol Diacrylate as a Nonadsorptive Polymeric Material for Microfluidics
Polydimethylsiloxane (PDMS), commonly used in microfluidics, is susceptible to nonspecific adsorption of molecules and biological analytes, such as proteins. PDMS requires coating or chemical modification to overcome this problem. We optimized a single-monomer formulation of polyethylene glycol diacrylate (PEGDA), which upon polymerization to form polyPEGDA, provides reduced susceptibility to n...
متن کاملPolyethylene Glycol 3350 With Electrolytes Versus Polyethylene Glycol 4000 for Constipation: A Randomized, Controlled Trial
OBJECTIVE The long-term efficacy and safety of polyethylene glycol (PEG) in constipated children are unknown, and a head-to-head comparison of the different PEG formulations is lacking. We aimed to investigate noninferiority of PEG3350 with electrolytes (PEG3350 + E) compared to PEG4000 without electrolytes (PEG4000). METHODS In this double-blind trial, children aged 0.5 to 16 years with cons...
