This paper presents heuristics for the integration of fermentation with the appropriate crystallization based in-situ product recovery (ISPR) technique. Here techniques, such as co-crystallization (CC), evaporative crystallization (EC), template induced crystallization (TIC), cooling crystallization (ClC) and electrochem. induced crystallization (EIC), that were recently developed or applied to fermentations were evaluated. For this purpose, the operating windows of fermentation and crystallization of the top-twelve platform chems. as identified by the US Department of Energy were extracted from literature and processed. The results show that in principle all mols. can be crystallized and confirm that different classes of platform chems. require different crystallization techniques. Finally, the results show that intensified crystallization, by means of utilizing external fields (EIC) or tunable solid state properties (CC), seems to be a very feasible ISPR technique.

Quality Control of (R)-4-Hydroxydihydrofuran-2(3H)-one. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (R)-4-Hydroxydihydrofuran-2(3H)-one, is researched, Molecular C4H6O3, CAS is 58081-05-3, about Synthesis and Nonenzymic Template-Directed Polymerization of 2′-Amino-2′-deoxythreose Nucleotides. Author is Blain, J. Craig; Ricardo, Alonso; Szostak, Jack W..

Threose nucleic acid (TNA) is a potential alternative genetic material that may have played a role in the early evolution of life. We have developed a novel synthesis of 2′-amino modified TNA nucleosides (2′-NH2-TNA) based on a cycloaddition reaction between a glycal and an azodicarboxylate, followed by direct nucleosidation of the cycloadduct. Using this route, we synthesized the thymine and guanine 2′-NH2-TNA nucleosides in seven steps with 24% and 12% overall yield, resp. We then phosphorylated the guanine nucleoside on the 3′-hydroxyl, activated the phosphate as the 2-methylimidazolide, and tested the ability of the activated nucleotide to copy C4 RNA, DNA, and TNA templates by nonenzymic primer extension. We measured pseudo-first-order rate constants for the first nucleotide addition step of 1.5, 0.97, and 0.57 h-1 on RNA, DNA, and TNA templates, resp., at pH 7.5 and 4 °C with 150 mM NaCl, 100 mM N-(hydroxylethyl)-imidazole catalyst, and 5 mM activated nucleotide. The activated nucleotide hydrolyzed with a rate constant of 0.39 h-1, causing the polymerization reaction to stall before complete template copying could be achieved. These extension rates are more than 1 order of magnitude slower than those for amino-sugar ribonucleotides under the same conditions, and copying of the TNA template, which best represented a true self-copying reaction, was the slowest of all. The poor kinetics of 2′-NH2-TNA template copying could give insight into why TNA was ultimately not used as a genetic material by biol. systems.
