A gram-negative nonmotile rod which was capable of using 1,2-(14)C-ethylene glycol as a sole carbon source for growth was isolated from a brine pond, Great Salt Lake, Utah. The bacterium (ATCC 27042) required at least 0.85% NaCl for growth and, although the chloride ion was replaceable by sulfate ion, the sodium ion was not replaceable by potassium ion. The maximal concentration of salt tolerat...

Is the recently found seepage groundwater on Mars pure H2O, or mixed with salts and other antifreeze compounds? Given the surface conditions of Mars, it is unlikely that pure water could either exist in its liquid state or have shaped Mars’ fluid erosional landforms (gullies, channels, and valley networks). More likely is that Mars’ seepage groundwater contains antifreeze and salt compounds tha...

The main goal of this study was to describe the method of the synthesis of the dodecyl-, tetradecyl-, hexadecyl- and octadecyl-propylene glycol emulsifiers in the presence of selected anionic and nonionic surfactants. Acyl propylene glycol emulsifiers were produced by esterification of propane-1,2-diol (propylene glycol, PG) with C12:0-C18:0 fatty acids in the presence of anionic sodium dodecyl...

The early literature indicates much confusion as to the origin of acetylmethylcarbinol and butylene glycol in microbiological fermentations. Happold and Spencer (1) have reviewed much of this early work and have studied in detail the conditions for the formation of acetylmethylcarbinol and butylene glycol from glucose and pyruvate by Aerobacter aerogenes. Juni (2) has demonstrated that acetoin ...

The cryopreservation of mammalian embryos has become an integral part of methods to control animal reproduction. Numerous vitrification solutions have been formulated with ethylene glycol in combination with macromolecules, sugars and other cryoprotective agents. These indicate that a study of ethylene glycol as a cryoprotectant of choice in vitrification studies would be promising. To understa...

OBJECTIVE In this study, anti-inflammatory effects of Royal Jelly were investigated by inducing renal inflammation in rats with the use of ethylene glycol. For this purpose, the calcium oxalate urolithiasis model was obtained by feeding rats with ethylene glycol in drinking water. MATERIALS AND METHODS The rats were divided in five study groups. The 1st group was determined as the control gro...

Background: We describe a case of acute ethylene glycol poisoning following ingestion of antifreeze agent in which serum ethylene glycol and anion gap were serially measured. Patients: A 66-year old man was hospitalized after intentional ingestion of automotive antifreeze. Upon admission, vital signs, mental status, and neurological functions were normal. Initial laboratory tests revealed no se...

The water relations of pepper plants (Capsicum frutescens L.) under conditions conducive to guttation were studied to evaluate the control of plant water stress with polyethylene glycols. The addition of polyethylene glycol 6000 to the nutrient solution resulted in water relations similar to those expected in soil at the same water potentials. Specifically, xylem pressure potential in the root ...

Ethylene glycol is most commonly found as the primary ingredient of automobile antifreeze and hydraulic brake fluids. The major use of ethylene glycol as an antifreeze is namely in automobiles, in air conditioning systems and in as de-icing fluid for windshields. It is a widely used chemical that is capable of causing significant injury if ingested. It is not intrinsically toxic but requires me...

BACKGROUND Ethylene glycol is highly toxic and represents an important cause of poisonings worldwide. Toxicity can result in central nervous system dysfunction, cardiovascular compromise, elevated anion gap metabolic acidosis and acute kidney injury. Many states have passed laws requiring addition of the bittering agent, denatonium benzoate, to ethylene glycol solutions to reduce severity of ex...
