An ion chromatographic method was developed which is able to separate five unsubstituted and hydroxy C4 dicarboxylic acids, succinic, malic, tartaric, maleic and fumaric acid, besides the other unsubstituted C2-C5 dicarboxylic acids, oxalic, malonic and glutaric acids, as well as inorganic ions in samples extracted from atmospheric particulate matter. By the application of this method it was fo...

Introduction: Succinic acid, containing two equivalent carboxylic acid carbons, is a prime molecule for use in hyperpolarization studies. Hyperpolarized succinate has many potential uses as it has been implicated as a paracrine signal for liver damage [1] and succinate dehydrogenase (SDH) has been shown to be a tumor suppressor [2]. Mutations in the SDH enzyme lead to accumulation of intracellu...

A multi-criteria strategy to identify sustainable bio-succinic acid production processes on a commercial scale.

The title compound, C(11)H(16)O(4), crystallizes with three molecules in the asymmetric unit. The cyclo-hexane ring adopts a chair conformation. Inter-molecular O-H⋯O hydrogen bonds are observed and these help to establish the crystal packing.

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...

In fermented products containing Bifidobacteria, factors such as organic acid concentration and b-galactosidase activity are important in the development of flavor and texture of final products. Both the process conditions and medium components have significant effects on fluctuation of such factors. The effects of whey permeate powder and yeast extract concentrations, as nitrogen sources was i...

In this study, a novel succinic acid producing bacterium was isolated from cow bovine rumen. Two bacteria’s are found to give better results for the production of succinic acid from the isolated colonies. Different synthetic carbon sources such as glucose, sucrose, fructose, dextrose, starch and cellulose and different crude carbon sources such as rice straw, sorghum stalk, baggase and sugar mi...

Succinic dehydrogenase is considered to be one of the most important enzymes that demonstrate the functional state of the parietal cell of gastric mucosa. Succinic dehydrogenase of the gastric mucosa was first done histochemically by Padykula with the parietal cell in rat. Thereafter many authors have described on the study of succinic dehydrogenase of the gastric mucosa and the relationship be...

Surface tension of ternary solution of sodium chloride, succinic acid and water was measured as a function of both composition and temperature by using the capillary rise technique. Both sodium chloride and succinic acid are found in atmospheric aerosols, the former being main constituent of marine aerosol. Succinic acid was found to de-5 crease the surface tension of water already at very low ...

Actinobacillus succinogenes, a typical succinic acid producing microorganism, was inhibited seriously by ammonium ion, which hampered industrialization of A. succinogenes with ammonium ion based material as the pH controller. In this study, we have isolated an ammonium ion-tolerant mutant of A. succinogenes by continuous-culture technique in which all environmental factors beside the stress (am...
