Abstract
An automatic colony counter was tested extensively with colonies of two bacterial species,
Serratia marcescens
and
Bacillus subtilis
var.
niger
, grown on agar media. A stable relationship was established between machine counts and counts done visually by technicians. The calibration curve and estimates of the efficiency of the machine are presented and discussed. It is estimated that a 40% reduction in colony counting time is feasible through use of the machine.
