Determination of bacterial cell volume with the Coulter Counter.

摘要

Two methods were used to determine mean volumes of cells of Escherichia coli B/rA in both stationary- and exponential-phase cultures, i.e., electronic measurement with a Coulter Counter-Analyzer system and biophysical measurement of the total volume and number of cells in sedimented cell pellets. Within experimental errors, the methods gave the same mean cell volumes.
