The Use of a Modified Differential Conductivity Particle Counter to Determine Differences in the Size-Distribution Profiles of Proliferating Microorganisms

摘要

Up to the present time, microbiological experiments have been conducted using assessment techniques which require long time periods for completion. The present program was carried out to demonstrate a new instrumental method which allows near-real-time readout of microorganisms concentrations and sizes, permitting effective replacement of the classical methods used to date. This instrumental method shows promise as a tool for discrimination between various particle shapes in the one to 100 micron particle size range. Preliminary experiments demonstrating the possibility of particle shape discrimination are described. (Author)
