More Information
Summary:One or more strains of luminous microorganisms are used as biological indicators in the detection of toxic substances or conditions in liquids. When exposed to toxic substances or conditions, the change in light output is sensed by light sensing apparatus. The amount of change in light output of the microorganisms is related to the concentration of toxic substance to which the organisms have been exposed. The cells are grown in a variety of ways and lyophilized cells, which have a long storage life, can be reconstituted and used in detection of toxic substances in accordance with the invention without further propagation.
