Use of the “Ferment-1” apparatus for identification of microorganisms by their proteolytic activity

Dissolving ammonia in an investigated solution causes a change in the e lect r ical conductivity of the lat ter . Elect rophysical methods of investigation, high-frequency conductometry in par t icular , a re used to record gas l iberation from solutions associated with changes of their e lect r ical conductivity. The principle of the method and a diagram of the " F e r m e n t l " apparatus were discussed in detail previously [1-2].
