Rapid Automated Bacterial Identification by Simultaneously Measuring Electrical Conductance and Transmitted Light Intensity
細菌の電気的・光学的同時測定による自動検査法
About This Article
Descriptions
The growth curve of bacterial culture of E. coli. was studied by simultaneously measuring the changes of electrical conductance and of transmitted light intensity of culture broth. From the observed curves, we estimated the numerical values of parameters (lag phase period, growing speed and metabolic period) expressing the growth curve of bacterial culture and concentration of bacteria E. coli. These values were in a reasonable range comparing with the published data about E. coli. The present result suggests a possibility that by our method we can rapidly and automatically identify the species of bacteria and estimate its concentration in the culture broth.
