Peptides of Yeast Saccharomyces cerevisiae Activated by the Aquatic Extract of Atriplex sibirica L.

“…Yeast is capable of both direct assimilation of amino acids in the presence of a complete mixture of amino acids in the culture medium and synthesis of the missing amino acids from the available ones . A complex mixture of amino acids, in comparison with a limited number of them, provides faster yeast growth.…”

“…The presence of significant content of proline in A. sibirica L. is not relevant because this amino acid is absorbed very little if at all by the yeast cells …”

“…It may be assumed that the decrease in the amount of aspartic and, in particular, glutamine acids in yeasts after treatment with the A. sibirica L. extract is associated with their participation in the biosynthesis of other nitrogenic compounds. , Aspartic acid can enter a transamination reaction with α-ketoglutaric acid, resulting in oxaloacetate and glutamine acid. In addition, aspartic acid is a precursor of aspartine and the nucleotides of pyrimidines (uracil, thymine, and cytosine).…”

“…sibirica L. (Figure ), especially group B, along with amino acids have a favorable effect on the physiological and biochemical characteristics of the yeast culture. For the growth and reproduction of brewer yeast of grassroots fermentation, the presence of biotin, inositol, and pantothenate in the medium is necessary, and some types of yeast of upper fermentation require the presence of thiamine and/or pyridoxine along with the aforementioned substances. , …”

A novel layered zirconium molybdate as a precursor to a ceramic zirconomolybdate host for lanthanide bearing radioactive waste

“…1,2 In this context, immobilization technologies involving inorganic sorbents are considered to be the most promising solutions of radioactive waste minimization and solidification in durable waste form. [3][4][5] The ceramization process by in situ heat treatment of a radionuclide-loaded inorganic sorbent to produce a crystalline or glass-crystalline ceramic waste form is being studied for a number of selective ion exchangers (tungsten bronze, 4 silicotitanates, [6][7][8] zeolites, [9][10][11] ammonium molybdophosphate/microsphere composite 12,13 ) and non-selective sorbents with an open-cell macroporosity loaded with waste solution by impregnation (cenosphere-derived aluminosilicate porous material called Gubka, 14,15 silica gel, 16 etc.) as a cost and energy saving technology that minimizes the risk of environmental contamination compared to sorbent vitrification or synthesis of ceramic hosts by another way.…”
