ABSTRACT:
An enzyme composition comprising a D-2-haloalkanoic acid halidohydrolase, bacteria containing said enzyme, a process for the preparation of said enzyme as a cell-free composition and a process in which the enzyme is used to increase the concentration of the L-enantiomer in a mixture of the D- and L-enantiomers of a 2-haloalkanoic acid. Preferably the 2-haloalkanoic acid is 2-bromo- or 2-chloro-propionic acid and the process for increasing the concentration is carried out under anaerobic conditions.
