Abstract
In a process for extracting glucose isomerase from microorganism cells containing glucose isomerase by the so called high pressure release and impact method in which the suspension of the microorganism cells is homogenized for the extraction by releasing the pressure applied on said suspension instantaneously and giving the suspension an impact at very high velocity, the concentration of the suspension containing microorganism cells and the pressure applied on the said suspension are selected within specific ranges, namely from 0.5 to 10 wt. % (on a dry substance base) and from 400 to 700 Kg/cm.sup.2, respectively.
