Toward net-zero sustainable aviation fuel with wet waste–derived volatile fatty acids

The Absorption of Soluble, Volatile Fatty Acids*

Experimental investigations show clearly that the absorption and metabolism of the short chain, water-soluble fatty acids differ in some way from those of the long chain fatty acids insoluble in water. Experiments by Lebedeff (1883), Leube (1895), Zunts (1901), and Eckstein (1929) show no evidence of the butyryl radical in the deposited fat when fed either as a fat or in the form of tributyrin....

Volatile Fatty Acids and Fatty Acid Composition of Silage Species

In this study, total fatty acid composition and volatile fatty acid of silage species in Turkey was determined by using Gas Chromatography (Shimadzu 15-A). Total lipids were extracted from the corn silage, alfalfa silage and figüre silage samples by the method of Folch et al. Silage species were a total of 15 different fatty acids. These fatty acids between C12 to C24 have changed. Unsaturated ...

Intrajejunal volatile fatty acids in the stagnant loop syndrome.

In the stagnant loop syndrome an abnormal anaerobic flora colonizes the small bowel. Anaerobic organisms are characterized by fermentation reactions leading to the production of volatile fatty acids. This paper describes the measurement of intrajejunal volatile fatty acid concentrations in 11 patients with the stagnant loop syndrome. Nine normal persons and 18 patients with gastrointestinal dis...

Blood cultures evaluation by gas chromatography of volatile fatty acids.

The volatile fatty acid profiles were determined by a simple gas chromatographic method in 375 microbiologically positive and negative blood cultures. Aerobic bacteria yielded profiles with low content of acids, some of which were chromatographically negative. Anaerobic bacteria produced more acids and more distinctive profiles. The method makes it possible to confirm the microbiological findin...
