Inhibition of the fermentation of propionate to methane and carbon dioxide by hydrogen, acetate, and propionate was analyzed with a mesophilic propionate-acclimatized sludge that consisted of numerous flocs (size, 150 to 300 {mu}). The acclimatized sludge could convert propionate to methane and ...

A unique spin coat process was developed which improves the coating uniformity and extends the range of applicable resist thicknesses typically encountered for a one viscosity photoresist. This spin coat process involves a high speed, short term initial coat followed by a low speed dry cycle. Advantages are seen in ...

anaerobic digestion are acetic, propionic, and butyric acids with lesser. 13] amounts of formic and valeric acids 3 . Propionic and valeric acids ...

Acetate, propionate, and butyrate are intermediate products in the anaerobic bioconversion of organic matter to methane and carbon dioxide. This study examines the effects of acetate, propionate, and butyrate on the thermophilic oxidation of propionate in continuous-flow methanogenic sludge bed ...

Vapor-liquid equilibrium (VLE) data have been measured for mixtures of ethyl acetate with acetic acid at 338 and 346 K and for mixtures of ethyl propionate with propionic acid at 358 and 368 K. The measurements were carried out in a recirculation still similar to that of Dvorak and Boublik. The data have been ...

The effects of acetate, propionate, and butyrate on the anaerobic thermophilic conversion of propionate by methanogenic sludge and by enriched propionate-oxidizing bacteria in syntrophy with Methanobacterium thermoautotrophicum delta H were studied. The methanogenic sludge was cultivated in an upflow anaerobic ...

Four cows with exteriorized carotid arteries were in an intensive study of concentrations in plasma and mammary extraction of propionate. A restricted-roughage, high-grain diet produced higher arterial propionate concentrations and larger carotid-subcutaneous abdominal vein (arteriovenous) differences that the control diet. Concomitant changes in ...

There is increasing evidence that gut microflora and fermentation processes in the large intestine are important for health, and that health-promoting effects are mediated by fermentation products. Usually analytical methods for these compounds are tedious. A simple and rapid procedure of aqueous extraction from the stools has been optimized. After extraction, an aliquot of the aqueous layer was ...
