摘要：
A process for the preparation of D-pantolactone, comprising employing specific microorganisms to convert D,L-pantolactone as the starting material into D-pantoic acid by selective asymmetric hydrolysis of the D-form only in the D,L-pantolactone, and then separating D-pantoic acid and converting it into D-pantolactone.
