Abstract
The synthesis of captopril as an important chiral drug in commerce needs expensive resolution process of racemic mixture. Microorganisms, producing a thermostable esterase that catalyzes the stereo-selective hydrolysis of methyl DL-${\beta}$-acetylthioisobutyrate (DL-ester) to D-${\beta}$-acetylthioisobutyric acid (DAT) were screened from soils. Among the strains tested, strain No CJ-317 and strain No CJ-187 with highest activity were selected as the best DAT producer. The newly isolated microorganisms were identified respectively, as Klebsiella pneumoniae and Pseudomonas putida. The cell activity of esterase from K. pneumoniae CJ-317 and P. putida CJ-187 were showed an optimal reaction activity at $75^{\circ}C$ and $60^{\circ}C$, respectively. Also the cell activity of K. pneumoniae CJ-317 was stable up to $80^{\circ}C$ for 1 h, while that of P. putida CJ-187 was not over $60^{\circ}C$. By varying the concentration of DAT in the reaction mixture, the cell activity of P. putida CJ-187 showed about 55% and 80% of product inhibition in the presence of 2.5% (w/v) and 5.0% of DAT respectively. K. pneumoniae CJ-317 had less product inhibition than P. putida CJ-187 by about 35% and 44% at the same concentrations respectively. The esterase of newly isolated K. pneumoniae CJ-317 could be useful for the stereo-selective hydrolysis of DL-ester to DAT.
