Enantioselective hydrolysis of racemic methyl mandelate by cell surface-displayed lipase

Time (h)	Enantiomeric excess (%)a		Conversion (%)b	Enantiomeric ratioc
	Remaining ester	Product
12	0	NDd	0
24	23.2 ± 1.6	99.0	19.0 ± 1.0	250
36	39.1 ± 2.5	99.0	28.3 ± 1.3	292

^aEnantiomeric excess (ee) = 100 × (A − B)/(A + B), where A and B are enantiomers and A is greater than B.

^bPercentage of conversion (c) = ee_s/(ee_s + ee_p), where subscripts s and p represent remaining ester and product, respectively.

^cEnantiomeric ratio (E) = ln[1 − c(1 + ee_p)]/ln[1 − c(1 − ee_p)].

^dND, not detected.
