Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 527-07-1, formula is C6H11NaO7, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Category: alcohols-buliding-blocks
Rogalski, Esther;Ehrmann, Matthias A.;Vogel, Rudi F. research published 《 Intraspecies diversity and genome-phenotype-associations in Fructilactobacillus sanfranciscensis》, the research content is summarized as follows. In this study the intraspecies diversity of Fructilactobacillus (F.) sanfranciscensis (formerly Lactobacillus sanfranciscensis) was characterized by comparative genomics supported by physiol. data. Twenty-four strains of F. sanfranciscensis were analyzed and sorted into six different genomic clusters. The core genome comprised only 43,14% of the pan genome, i.e. 0.87 Mbp of 2.04 Mbp. The main annotated genomic differences reside in maltose, fructose and sucrose as well as nucleotide metabolism, use of electron acceptors, and exopolysacchride formation. Furthermore, all strains are well equipped to cope with oxidative stress via NADH oxidase and a distinct thiol metabolism Only ten of 24 genomes contain two maltose phosphorylase genes (mapA and mapB). In F. sanfranciscensis TMW 1.897 only mapA was found. All strains except those from genomic cluster 2 contained the mannitol dehydrogenase and should therefore be able to use fructose as external electron acceptor. Moreover, six strains were able to grow on fructose as sole carbon source, as they contained a functional fructokinase gene. No growth was observed on pentoses, i.e. xylose, arabinose or ribose, as sole carbon source. This can be referred to the absence of ribose pyranase rbsD in all genomes, and absence of or mutations in numerous other genes, which are essential for arabinose and xylose metabolism Seven strains were able to produce exopolysaccharides (EPS) from sucrose. In addition, the strains containing levS were able to grow on sucrose as sole carbon source. Strains of one cluster exhibit auxotrophies for purine nucleotides. The physiol. and genomic analyses suggest that the biodiversity of F. sanfranciscensis is larger than anticipated. Consequently, “original” habitats and lifestyles of F. sanfranciscensis may vary but can generally be referred to an adaptation to sugary (maltose/sucrose/fructose-rich) and aerobic environments as found in plants and insects. It can dominate sourdoughs as a result of reductive evolution and cooperation with fructose-delivering, acetate-tolerant yeasts.
527-07-1, Sodium Gluconate is the sodium salt of gluconic acid with chelating property. Sodium gluconate chelates and forms stable complexes with various ions, preventing them from engaging in chemical reactions.
Sodium gluconate is an organic sodium salt having D-gluconate as the counterion. It has a role as a chelator. It contains a D-gluconate.
D-Gluconic acid sodium salt is a glycol ether that is used as an injection solution. It has been shown to have antibacterial efficacy against wild-type strains of bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The in vitro antimicrobial action of D-gluconic acid sodium salt was found to be due to its ability to inhibit bacterial growth by interfering with the synthesis of DNA. D-gluconic acid sodium salt also has been shown to have antihypertensive effects in rats through the inhibition of angiotensin II type 1 receptor (AT1) signaling pathway and erythrocyte proliferation. This drug also has been shown to bind benzalkonium chloride and x-ray diffraction data show that it is crystalline in nature. The analytical method for determining the concentration of D-gluconic acid sodium salt is by electrochemical impedance, Category: alcohols-buliding-blocks
