Akihiro Sakimae,Hosoi Akihiko,Kobayashi Etsuko,Naoto Ohsuga,Ryozo Numazawa,Ichiro Watanabe,Hisao Ohnishi +6 more
TL;DR: D-β-acetylthioisobutyric acid-producing ability was found in 15 strains belonging to the genera Pseudomonas, Agrobacterium, Enterobacter, Cellulomona, Rhodococcus, Brevibacteriaium, and Torulopsis.
Patent
Production of optically active carboxylic acid and its antipode ester
TL;DR: In this paper, a carboxylate ester of formula I (R1 is alkyl, aryl, etc.; R2, R3 are alkyls; (n) is 1, 2) is treated with an immobilized vital catalyst to provide the objective compound of formula II, the catalyst being produced by treating bacterial cells with a multifunctional crosslinking agent, and the bacterial cells having an ability to asymmetrically hydrolyze the ester bond.
Patent
Recombinant plasmid having gene of enzyme asymmetrically hydrolyzing carboxylic acid ester, microorganism transformed therewith and production of optically active carboxylic acid ester with said microorganism
TL;DR: In this paper, an esterase gene of Pseudomonas was inserted into plasmids pUC18 and pUC19 to produce an optically active carboxylic acid.
Patent
Production of optically active carboxylic acid and antipodal ester thereof
TL;DR: In this paper, an optically active carboxylic acid expressed by formula II (R1, R2 and n are same as those described above) and antipodal ester thereof produced in the reaction solution are subsequently subjected to extraction treatment, separated and purified by column chromatography, etc.
Patent
Production of optically active carboxylic and antipodal ester thereof
TL;DR: In this article, the authors describe an approach to improve production efficiency by reacting a specific ester with a culture solution, etc., of a microorganism, belonging to the genus Corynebacterium and having the ability to asymmetrically hydrolyze ester bonds.
