    摘要： The present invention provides a process for production of amide compounds, which includes converting a nitrile compound into its corresponding amide compound by hydrating the nitrile compound in the presence of a cultured broth of bacterial cells, intact bacterial cells, disrupted bacterial cells or enzymes contained therein, or immobilized preparations obtainable by immobilizing intact bacterial cells, disrupted bacterial cells or enzymes contained therein, the bacterial cells being those of a biologically pure culture of a thermophilic microorganism having hydration activity to convert a nitrile compound into its corresponding amide compound, such as Bacillus smithii SC-J05-1 (FERM BP-4935).

    摘要： There is provided a method for improving optical purity of an amine compound of the formula I: ##STR1## wherein R.sup.1 indicates a phenyl group which may be substituted or an aralkyl group having 7 to 10 carbon atoms which may be substituted, and R.sup.2 indicates an alkyl group having 1 to 6 carbon atoms, which is characterized by contacting a cutlture of a microorganism belonging to Arthrobacter having an ability to preferentially metabolize one optical isomer based on an asymmetric carbon atom to which an amino group bonds in the amine compound of the formula I or a treated product thereof with the amine compound of the formula I.
