Xanthan gum modified fish gelatin and binary culture modulates the metabolism of probiotics in fermented milk mainly via amino acid metabolism pathways was written by Le, Yi;Yang, Hongshun. And the article was included in Food Research International in 2022.Recommanded Product: 1,2-Propanediol This article mentions the following:
1H NMR combined with multivariate data anal. were applied to investigate the effects of fish gelatin (FG) addition and co-culture of Lactobacillus acidophilus LA-5 (La-5) and Bifidobacterium lactis BB-12 (Bb-12) on the growth and metabolic pathways of the probiotics themselves. The results showed that the addition of FG had no significant effects on the growth of probiotics, but co-culture did promote the growth of probiotics, especially for Bb-12 (up to 2 log CFU/mL). FG addition inhibited amino acids synthesis and TCA cycling in Lacticaseibacillus paracasei subsp. paracasei CASEI 431 (L431) to some extent. However, for the single La-5 strain, these pathways were promoted. As for mixed bacterial cultures, Bb-12 promoted amino acids metabolism, sugar transport and energy metabolism in La-5. These findings suggested that the metabolic profile of probiotic bacteria can be adequately explained by metabolic pathway anal., which also provides theor. guidance for the industrialization of functional fermented milk. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Recommanded Product: 1,2-Propanediol).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. The oxygen atom of the strongly polarized O鈥旽 bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Recommanded Product: 1,2-Propanediol
