Volume 72, no. 2, p. 1639–1644, 2006. There was a minor error in the calculation of volumetric productivity. Page 1641, column 2, line 35: “10 mM h 1 or 25.9 g liter 1 day ” should read “8.1 mM h 1 or 21 g liter 1 day 1 (based on the packed bed void volume).” The derived value for specific productivity should change from 8.11 g (g biomass) 1 day 1 to 6.6 g (g biomass) 1 day 1 (page 1639, line 16; page 1641, column 2, line 37; page 1643, column 2, line 3). Accordingly on page 1643, column 1, line 19, the statement “were more than twofold higher” should change to “were higher.” Page 1643, Table 1: the value for (S)-styrene oxide specific productivity should be 5.5. These changes do not alter the overall results or any conclusion of the study.
