翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Reuterin ： ウィキペディア英語版 Reuterin Reuterin is a potent antimicrobial multi-compound produced by ''Lactobacillus reuteri'', during the metabolism of glycerol to 1,3-propanediol catalysed by the coenzyme B12-dependent diol dehydrase. Reuterin consists of 3-hydroxypropionaldehyde, its hydrate, and its dimer in dynamic equilibrium. At concentrations above 1.4M, the HPA dimer is predominant; at concentrations relevant for biological systems, however, HPA hydrate is the most abundant, followed by the aldehyde form. Reuterin inhibits the growth of some harmful Gram-negative and Gram-positive bacteria, along with yeasts, molds, and protozoa. ''L. reuteri'' can secrete sufficient amounts of reuterin to inhibit the growth of harmful gut organisms, without killing beneficial gut bacteria, allowing ''L. reuteri'' to remove gut invaders while keeping normal gut flora intact. Reuterin is water-soluble, effective in a wide range of pH, resistant to proteolytic and lipolytic enzymes, and has been studied as a food preservative or auxiliary therapeutic agent.〔Vollenweider S, Lacroix C: 3-hydroxypropionaldehyde: applications and perspectives of biotechnological production.

J Food Prot 1999, 62(3):257-261.〕 ==Efficacy== Reuterin as an extracted compound has been shown capable of killing Escherichia coli O157:H7 and Listeria monocytogenes, with the addition of lactic acid increasing its efficacy. It has also been demonstrated to kill Escherichia coli O157:H7 when produced by L. reuteri. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Reuterin」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
