Short-chain fatty acids can be produced under anaerobic conditions by fermentative soil microbes and have nematicidal properties. We evaluated the effects of butyric and propionic acids on death and recovery of stunt nematodes (Tylenchorhynchus spp.), a common parasite of turfgrass. Nematodes in a sand-soil mix (80:20) were treated with butyric or propionic acid and incubated under air or N for...

In connection with attempts in this laboratory to increase the yields of threonine in isolations from various prtiteins, it recently became essential to determine its isoelectric point. During the time since the isolation and identification of threonine by Rose and coworkers (1) and its subsequent synthesis by West and Carter (2), the isoelectric point of the pure compound has not been reported...

The aim of the present study was to measure organic acid, especially lactic acid, concentrations in contents of the stomach and intestine of wildcaught and cultured ayu (Plecoglossus altivelis) and wild-caught seema (Oncorhynchus masou), and of the stomach as well as anatomically defined three intestinal segments of wild ayu. The concentration of total SCFA in the present study was approximatel...

Nodal explants of Phyla nodiflora (L.) Greene, were cultured on Murashige and Skoog (MS) medium supplemented with different combination and concentration of cytokinins and auxins for multiple shoots regeneration. The maximum numbers of shoots were found in MS medium supplemented with2.5 mgl-16-benzylaminopurine (BA) and 0.5 mgl-1 kinetin (KN). Elongated shoots were transferred to rooting ...

The convenient, high yielding and diastereoselective synthesis of α-amino-β-substituted-γ,γ-disubstituted butyric acid derivatives was carried out by a three-component tandem reaction of a chiral equivalent of nucleophilic glycine. The reaction was performed smoothly under mild conditions and enabled the construction of two or three adjacent chiral centers in one step, thus affording a novel an...

Diabetes mellitus type 2 (DMT2) affects hundreds of millions of people globally and costs billions of dollars each year. The importance of research toward prevention and treatment of this disease cannot be overestimated. Butyric acid is a short chain fatty acid that has been shown in mice and in intestinal cell culture studies to increase insulin sensitivity at the level of gene expression. How...

Carbohydrat,es are fermented by Clostridium acetobutylicum and related microorganisms with the formation of acetic acid, n-butyric acid, acetone, ethanol, and n-butanol. It has been conclusively proved that the butanol arises by the reduction of the butyric acid (1, 2). As yet, however, there is no exact information as to the sequence of reactions by which butyric acid is formed from glucose by...

Early workers in the field of ruminant physiology were aware of the presence of formic, acetic, propionic and butyric acids (Tappeiner, 1884), and of smaller amounts of higher members of the saturated fatty acid series (Mangold, 1934), in the rumen fluid. Accurate data were not reported, however, until recently, when partition chromatography became available as an analytical procedure for the a...

BACKGROUND Recent progress in production of various biofuel precursors and molecules, such as fatty acids, alcohols and alka(e)nes, is a significant step forward for replacing the fossil fuels with renewable fuels. A two-step process, where fatty acids from sugars are produced in the first step and then converted to corresponding biofuel molecules in the second step, seems more viable and attra...

Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. Strong consumer sentiment against the consumption of petro-chemical derived products yi...
