Abstract:
An electrooptical apparatus for controlling cell growth in microbiological culture comprising:an electrooptical cell filled up with a cell suspension and having electrodes and two orthogonal optical channels for passing through two light beams;a light source for irradiating light beams onto said electrooptical cell in two orthogonal directions;electrical generating means for supplying an alternating electrical current on said electrodes for inducing an alternating electrical field with predetermined frequency and strength in said electrooptical cell to provide orientation of bacterial cells of the microbiological culture;optical system focusing two perpendicular light beams passed through said electrooptical cell to a light detector and for generating signals in response to the optical density changes in said perpendicular light beams by turning on and turning off said alternating electrical field;temperature controlling means for controlling the temperature of said electrooptical cell;cell suspension delivery means connected to said electrooptical cell for delivering said and cell suspension to said electrooptical cell;an electronic unit receiving said signals from said optical system, controlling said electrical generating means and said cell suspension delivery means, determining and displaying growth parameters of said bacterial cells.
