A gas chromatographic procedure is described for quantitative estimation of alpha-hydroxy-beta 1 beta-dimethyl-gamma-butyrolactone (pantolactone). The chromatography was carried out using "LHM-8MD" apparatus equipped with a flame ionization detector. Columns with chromaton N-AW modified by 5% silicone XE-60 were used, helium

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
