Abstract
An enzymatic catalyst in the granular form which is non-dispersible in water comprising an inner core provided with a coating which coating comprises an enzymatic material characterised in that the coating has a thickness of from 30 to 400 microns and the ratio of the size of the core to the thickness of the coating is from 2 to 20. A method for the preparation of the catalyst and the use of the catalyst in the conversion of 2-hydroxy-4-methylthio butyronitrile to ammonium 2-hydroxy-4-methylthio butanoate is also claimed.
