D-Pantonohydrolase has attracted increasing attention as a biocatalyst for stereospecific production of D-pantoic acid. The Fusarium moniliforme D-pantonohydrolase was selected for directed evolution through error-prone Polymerase Chain Reaction (PCR) combined with DNA shuffling for improved activity and pH stability using

Dilute solutions of (R)-(-)-pantolactone in CCl4 were studied by polarimetry in conjunction with theoretical calculations of [alpha]D. Our data demonstrate that the self-association of a chiral solute results in a change in [alpha]D that can be accounted for by the

Addition of beta-cyclodextrin improves enantioselectivity dramatically in the reduction of ketopantolactone mediated by baker's yeast. It has been found that the selectivity increases with the decrease in concentration of ketopantolactone in bulk solvent, and beta-cyclodextrin controls its effective concentration. The
