title: Isolation and properties of alpha-amylase from perienteric fluid of Ascaris suum.
abstract: The properties of alpha-amylase from perienteric fluid of Ascaris suum were studied. The enzyme is strongly activated by chlorides at a simultaneous shift of pH optimum. It is fully activated already at 10(-3) M concentration of chlorides. A method of alpha-amylase isolation was modified with respect to these properties to give the purification degree 278 and yield of 11%.
