Experiments were conducted to determine the effect of fumaric acid supplementation and buffering capacity of the diet on ileal and fecal digestibilities of CP, GE, and amino acids in early-weaned pigs. In two experiments, 12 pigs each were weaned at 14 d of age and fitted with a simple T-cannula at the distal ileum between 15 and 17 d of age. In both experiments, the pigs were fed four diets, b...

Microbial production of C(4) dicarboxylic acids from renewable resources has gained renewed interest. The yeast Saccharomyces cerevisiae is known as a robust microorganism and is able to grow at low pH, which makes it a suitable candidate for biological production of organic acids. However, a successful metabolic engineering approach for overproduction of organic acids requires an incorporation...

Dr. Ulrich Schmid, 17, rue de l’Hôtel de Ville, CH-1800 Vevey (Suisse) We read with great interest the paper on the risk of sensitization upon topical application of fumaric acid derivatives by de Haan et al. [1]. Although in our wide personal experience oral dimefhylfumarates have proven effective in psoriasis in 70% of the cases, it cannot be emphasized enough that topical application should ...

1. It has been shown that Penicillium charlesii continues to synthesize galactocarolose when l-malic acid, malonic acid, succinic acid, fumaric acid, maleic acid or oxaloglycollic acid is substituted for dl-tartaric acid in the Raulin-Thom nutrient medium. 2. The quantity of galactocarolose synthesized per g. of mycelia was markedly decreased by substitution of l-malic acid, malonic acid, succi...

While localized variants of granuloma annulare are typically self-limited, disseminated granuloma annulare tends to be chronic and often therapy-resistant. Treatment with fumaric acid esters is effective for severe forms of psoriasis. Disseminated granuloma annulare has also been reported to respond to fumaric acid esters. We treated 8 patients (mean age 64.2 years; 4 men, 4 women) with low-dos...

UNLABELLED The naturally occurring compound, fumaric acid, was evaluated as a potential preservative for the long-term storage of cucumbers. Fumaric acid inhibited growth of lactic acid bacteria (LAB) in an acidified cucumber juice medium model system resembling conditions that could allow preservation of cucumbers in the presence of sodium benzoate. Forty millimolars of fumaric acid were requi...

The objective of this study was to determine whether supplementing organic acids can prevent incidences of subacute ruminal acidosis (SARA) in beef heifers fed a diet consisting of 8% barley silage and 92% barley grain-based concentrate (DM basis). Ten ruminally cannulated Hereford crossbred heifers (484 ± 25 kg BW) were used in a replicated 5 × 5 Latin square design with 14-d periods including...

The title complex, [Pr(2)(C(4)H(2)O(4))(3)(C(4)H(4)O(4))(H(2)O)(2)](n), was synthesized by reaction of praseodymium(III) nitrate hexa-hydrate with fumaric acid in a water-ethanol (4:1) solution. The asymmetric unit comprises a Pr(3+) cation, one and a half fumarate dianions (L(2-)), one half-mol-ecule of fumaric acid (H(2)L) and one coordinated water mol-ecule. The carboxyl-ate groups of the fu...

Low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. It was thought that the HPLC is the best method of the determination of organic acids in the apple juice. In this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for ...
