ABSTRACT:
The present invention relates to a method for the preparation of a purified amylase recovered from a fermentation broth, by the addition of a precipitation agent which is a halide salt, most preferably sodium or potassium chloride. According to a preferred embodiment, a further precipitation agent is added which is an organic compound, most preferably an alkyl ester of 4-hydroxybenzoic acid.
The present invention also relates to the purified amylases so obtained and to the uses of these purified amylases.
