Abstract
A process for making L-aminoacylase includes a cultivation of microorganism selected from a specy of Alcaligenes, especially the Alcaligenes denitrificans DA 181, and a separation of a produced L-aminoacylase from the bacterial cells for obtaining the L-aminoacylase which may be further purified for the production of L-amino acid. The acylase made by such a process may have an increased stability, beneficial for its commercial and medical values.
