title: Development of cellular absorptive tracers for quantitative characterization of microbial mass in flow systems.
abstract: We report a new cellular absorptive tracer (CAT) method for simple, nondestructive characterization of bacterial mass in flow systems. Results show that adsorption of a CAT molecule into the cellular mass results in its slowdown during flow, which is an accurate quantitative measurement of biomass quantity and distribution. No such methods are currently available for quantitative characterization of cell mass.
