Reports from Kyung Hee University Highlight Recent Findings in Hydrolases

February 19, 2014

By a News Reporter-Staff News Editor at Biotech Week -- A new study on Enzymes and Coenzymes is now available. According to news reporting from Gyeonggi Do, South Korea, by NewsRx journalists, research stated, "(S)-Styrene oxide, (S)-2-chlorostyrene oxide (CSO), (S)-3-CSO and (S)-4-CSO with 99.9 %ee were obtained with a yield of 20.6, 39.3, 28.7 and 26.8 % from 4 mM corresponding racemic substrates using 10 mg cells of a newly-isolated Sphingopyxis sp. at pH 8.0 and 25 A degrees C in 1 ml 100 mM Tris/HCl buffer after 420, 100, 120 and 55 min, respectively."

The news correspondents obtained a quote from the research from Kyung Hee University, "For racemic 2CSO, well-known for one of the racemates that is difficult to obtained in enantiomerically pure form, (S)-2-CSO with 99.9 %ee, 39.3 % yield (theoretical yield 50 %) and enantiomeric ratio of 42.1 was obtained."

According to the news reporters, the research concluded: "The newly-isolated strain can thus be used as whole-cell biocatalyst in the production of various (S)-CSO with a chlorine group at different positions."
