  • Title: Isolation and characterization of Acinetobacter sp. ES-1 excreting a lipase with high enantioselectivity for (S)-ketoprofen ethyl ester.
    Author: Lee KW, Shin GS, Bae HA, Shin HD, Lee YH.
    Journal: Biotechnol Lett; 2004 Nov; 26(21):1639-42. PubMed ID: 15604812.
    Abstract:
    A new Acinetobacter sp. ES-1, grown on triolein, tryptone and Triton X-100, excreted a lipase that hydrolyzed 10 mM (R,S)-ketoprofen ethyl ester into (S)-ketoprofen. The crude lipase had an activity of 10 U ml(-1) and, at 30 degrees C and pH 7 over 48 h, gave a conversion yield of 35% with an enantiomeric excess for the product 96%.
