SYNERGIC EXTRACTION OF PANTOTHENIC ACID WITH TWO DIFFERENT EXTRACTANTS

Microbic Decomposition of Pantothenic Acid.

The metabolism of pantothenic acid.

The formulation of this pathway was based on: (a) the finding that cysteine supplies the sulfur-containing moiety of CoA (3,4); (b) the activities of pantetheine and pantothenylcysteine as growth factors for Acetobacter suboxydans (4-6) and Lactobacillus helveticus (7); (c) the presence of enzymes in these two organisms and also in Lactobacillus bulgur&s which decarboxylate pantothenylcysteine ...

Physicochemical study of extractants for extraction of rare earth element

Background: In nuclear technology, the solvent extraction is an important step for recovery of rare earth materials, purification, radionuclide production, and preparation of nuclear reactor materials. Tributyl phosphate (TBP) and toluene are taken as extractant and diluent, respectively, for study of extraction efficiency for rare earth element like CeO2. Methods: In the present paper, idea of...

Extraction of Molybdenum (VI) and Vanadium (V) from Nitrate Solutions Using Coupling of Acid and Solvating Extractants (RESEARCH NOTE)

In this study, solvent extraction method has been utilized for separation of molybdenum and vanadium from nitrate solution by utilizing coupling of acid and solvating extractants (D2EHPA and TBP extractants). The outcomes demonstrated that synergistic solvent extraction improves stability of formatted complexes for transfer to the organic phase. The main parameters such as pH value, concentrati...

Comparative Study on Pantothenic Acid Separation by Reactive Extraction with Tri-n-octylamine and Di-(2-ethylhexyl) Phosphoric Acid

Vitamin B5 was isolated from yeast in 1933, and a few years later from liver, by R.J. Williams. The main role of pantothenic acid in cells is the synthesis of coenzyme A, as well as the synthesis and metabolism of proteins, carbohydrates and fats. Regarding the human body, this compound is involved in the health of the digestive, nervous, circulatory, and skeletal systems, skin and hair, as wel...
