PURPOSE:To measure the biological activity simply and quickly, by contacting both the devices in which one set of the device is coated with biological constituent opaque membrane for the cathode among two sets of constant potential devices and giving a specified potential. CONSTITUTION:The electrodes 2, 3 of the constant potential devices provided in a tank 1 have two electrodes 4, 5, and one electrode of one constant potential device is covered with a membrane 6 of microbe, biological or botanical constituent opaque nature. Leads are connected to a device 7 which gives a given potential (electrolyte) from the respective electrode, and to a recorder 8. The electrode active substance in microbe (bacterium) and fermentation liquid (formic acid, hydrogen and coferment) is in contact with the cathode of the electrode 2 to produce currents and voltages. On the other hand, only the electrode active substance is also in contact with the electrode 3 of the constant potential devices to produce currents and voltages. The difference of currents and voltages of the two constant potential devices is an electric signal relating to the microbe activity, which is used for the measurement of activity of animal/botanical cells. |
